96-8913A.book Page 9 Monday, May 18, 2015 7:55 AM

3.1.2 Lathe Setup - Workholding

A drawback collet is required for bar feed applications. The Bar Feeder holds the push rod in place while the lathe drawtube clamps. If the collet does not pull the bar stock against the push rod when the drawtube clamps, length variation can occur and accuracy cannot be guaranteed.

NOTE: Your collet should also have a chamfered lead-in for smooth bar

feeding.

F3.2: Drawback Collet Example. [A] Collet Unclamped; [B] Collet Clamped. [1] Chamfered

Collet Lead-In, [2] Collet Closer Body, [3] Collet, [4] Bar Stock

Operation

Bar Feeder Setup

3.1.3 Lathe Setup - Haas Spindle Liners

Spindle liners adapt the size of your spindle bore to fit the bar stock that you process. This lets the bar stock feed and run smoothly. Properly fit spindle liners also help to reduce vibration and bar whip.

NOTE: Spindle liners do not grip the bar stock. If you have problems with

vibration or poor surface finish in your application, check the clearance between the bar and the liner. Use a closer-fitting liner if possible.

Put the Bar Feeder in the Lathe Setup position to install spindle liners.

Haas manufactures (2) types of spindle liners; extruded spindle liners, which fit most Haas lathes, and a bar-guide-and-spacer spindle liner system for 4"-bar-capacity lathes. The installation instructions for both liner types are available in the online Haas Resource Center. To retrieve the instructions:

1. Go to www.HaasCNC.com

2. Select the “Search by AD Number” option.

3. Type the number of the document you want to see:

• For the extruded spindle liner kit, use AD0021.

• For the bar-guide-and-spacer kit, use AD0020.

4. Select “Apply”.

Lathe Setup - Other Spindle Liners

Haas extruded spindle liners are designed to fit a wide range of bar stock sizes, and their one-piece finned design helps keep the bar stock centered in the spindle. If you use the bar-guide-and-spacer system or another spindle liner, remember these points:

• The liner passage for the bar must fit the bar as closely as possible while still letting the bar move through smoothly. The larger your bar stock is in diameter, the closer the liner must fit.

• The liner must be centered in the spindle.

• Make custom liners or bar-guide disks with a generous lead-in chamfer. The Haas bar-guide disks use a 0.25" chamfer at 45 degrees.

3.1.4 Bar Setup - Load Bars

Make sure that the bars you use are appropriate for your setup:

Operation

• Test the fit of the bar stock in the spindle liner. The liner must fit close but be large enough to let the bar pass through freely. Use a different liner if necessary.

• To determine the minimum bar length: Measure the gap between the end of the transfer tray and the lathe spindle liner. Multiply this distance by 2.25. Each bar must be at least as long as the result. For example, if the distance between the end of the transfer tray and the lathe spindle is 6.75" (171 mm), each bar must be at least 15.2" (386 mm) long.

• Bar stock must be straight.

• Add a chamfer to the leading end of the bar for better initial feeding. The leading end of the bar should have no sharp edges.

• Bar stock must be cut square on the end that contacts the bar pusher, to prevent protrusions or length variation.

• The bar stock should not extend outside of the spindle liner.

• Large-diameter, heavy bar stock must be shorter than 36" (813 mm).

• It is good practice to wipe the bars clean before you load them. Dirt and debris increase liner wear and could also become jammed inside the liner.

Load bars, one at a time, into the charging tray in a single layer. Push shorter bars toward the lathe. Do not let the bars stack. If the bars roll over each other as you load them, adjust the charging tray to a shallower angle.

Bar Feeder Setup

F3.3: Bar Loading Example. [1] Align the Leading Ends of the Bars with the Edge of the Tray. [2]

Do Not Stack the Bars.

Hexagonal Bar Stock

If you use hexagonal bar stock:

• Hexagonal liners are highly recommended. They should maintain a consistent orientation inside the spindle.

• If you use the bar-guide-and-spacer style of spindle liners, the first (2) guide disks should have hexagonal holes, oriented with the collet.

• The V-shape of the transfer tray keeps hexagonal stock in a consistent orientation.

• The lead end of the bar should have a 30-degree chamfer.

• Use M19 commands to set the spindle orientation to align the collet flats with the bar flats. in the bar feeder tray. Note that the spindle orientation option is necessary to do this.

96-8913A.book Page 13 Monday, May 18, 2015 7:55 AM

3.1.5 Bar Setup - Transfer Tray Adjustment

The transfer tray provides the bar stock a path that leads into the lathe spindle. When your Bar Feeder was installed, the service technician adjusted the Bar Feeder height to align the lathe spindle with the adjustment range of the transfer tray. With this procedure, you raise or lower the transfer tray to adjust it for the bar diameter.

1. Press [EMERGENCY STOP] on the lathe.

2. Put the Bar Feeder in the Feed/Auto position.

3. Put a piece of bar stock in the transfer tray.

Operation

4. Use the wheel to adjust the transfer tray height. Turn it clockwise to raise the tray and counterclockwise to lower the tray. As you adjust the transfer tray height, move the bar into the spindle liner by hand. Continue to adjust the transfer tray height until the bar slides freely into the liner.

5. Make sure that the collet is set for the diameter of the loaded bar:

a. With the collet open and the spindle stopped, slide the bar into the spindle liner

and collet by hand, and check for misalignment, binding or interference.

b. Remove the bar and place it in the charging tray.

3.1.6 Bar Setup - Push Rod Installation / Removal

The Bar Feeder comes with push rods that are 3/4" and 3/8" in diameter. Use the 3/8" push rod for all round stock material that is smaller than 0.8" (20 mm) in diameter. Use the 3/4" push rod for material 0.8" (20 mm) in diameter and larger.

CAUTION: Do not use the 3/8" push rod to push bars larger than 0.8" in diameter.

The push rod can bend.

To change the push rod:

1. Press [EMERGENCY STOP] on the lathe. Open the set-up lid.

2. At the lathe end of the push rod, slide the bushing retainer away from the push rod.

3.1.7 Bar Feed Variable Setup

When you set up your bar feed application, you define the push lengths with variables.

F3.6: Bar Feed Variables Example. Dimensions are not to scale. [A] Reference Point, [B]

Finished Part Length, [C] Facing Allowance, [D] Cutoff Allowance

Operation

• #3100 (Part Length + Cutoff): This is the total length of the finished part, plus allowances for face clean-up and part-off cuts. This is the distance that the Bar Feeder pushes the bar on every push after the initial push.

• #3101 (Initial Push Length): The distance the Bar Feeder pushes the material past the reference point (refer to page 17). The examples given in this manual use a reference point at the collet face. This is the distance that the Bar Feeder pushes each new bar for the first time.

• #3102 (Minimum Clamping Length): The minimum length of bar necessary to safely clamp and machine the workpiece. This is also called the remnant length, but the actual remnant can be longer.

To set up the variable positions:

1. Press [CURRENT COMMANDS].

F3.7: Bar Feeder Current Commands Display

Min. 1/4"

(6.4mm)

96-8913A.book Page 16 Monday, May 18, 2015 7:55 AM

Bar Feeder Setup

2. Press [PAGE UP] or [PAGE DOWN] to find the BAR FEEDER page.

3. Highlight the variable that you want to edit.

4. Type the value and press [ENTER].

Example:

#3100=2.150 (2.0" long part + 0.125" cutoff tool width + 0.025" facing allowance)

#3101=2.5 (2.5" of stock pushed past face of the collet)

#3102=3.0 (3.0" of material to clamp. During subsequent bar feeds, the machine will not

push the bar farther than a safe clamp position.)

Push Rod Clearance for #3102

CAUTION: Make sure that the push rod maintains 1/4" (6.4 mm) of clearance

between it and the collet chamfer. This clearance is necessary to make sure that the push rod does not come in contact with collet clamping surfaces.

To set push rod clearance:

1. Set macro variable #3102 MIN CLAMPING LENGTH to 1/4" (6.4 mm) from the collet clamping surfaces.

F3.8: Minimum Clamping Length: [1] Push Rod, [2] Collet, [3] Workpiece

CAUTION: This diagram is for reference only. Workholding varies in form and

function. It is your responsibility to keep the push rod 1/4" away from workholding surfaces.

96-8913A.book Page 17 Monday, May 18, 2015 7:55 AM

3.1.8 Reference Position Setup

The reference position is the zero point that the Haas Bar Feeder uses for all push operations. You usually establish the reference point at the face of the collet or the chuck jaws.

NOTE: You must reset the reference position each time you change the

workholding or move the Bar Feeder. When you change jobs, you do not need to establish a new reference position unless the new job uses different workholding.

To set up the reference position:

1. If there is a workpiece in the lathe, remove it.

2. Make sure the lathe door and the set-up lid are closed.

Operation

3. Type G105 Q4 ; in MDI mode, and then press [CYCLE START].

The Bar Feeder loads a bar and pushes it toward the face of the collet.

4. After machine motion stops, press [RESET]. You can now use the jog handle to move the Bar Feeder.

5. Jog the material to the reference position that you want to use, usually flush with the collet face.

6. Clamp the workholding.

7. Make sure the lathe door and the set-up lid are closed.

8. Command G105 Q2 ; (Set Reference Position).

The machine records the position, then pushes the bar the distance specified in variable #3101 (Initial Push Length). In the variable setup described above, this is

2.5" past the reference point.

9. Measure the bar to make sure that the Bar Feeder pushed the stock the correct distance.

96-8913A.book Page 18 Monday, May 18, 2015 7:55 AM

Bar Length Reset Procedure

3.1.9 Bar Setup - Charging Tray Angle Adjustment

The charging tray holds the supply of bar stock for the load fingers to pick up and move onto the transfer tray. Use the adjustment handle under the tray to adjust the tray angle.

F3.9: [1] Charging Tray Angle-Adjustment Handle

1. Turn the adjustment handle under the charging tray to adjust the feed angle. For most round stock, the charging tray angle should be approximately 5 degrees above horizontal.

2. Type this test program into the lathe control and watch the Bar Feeder operation. Make sure that bars feed reliably from the tray into the feed mechanism. You do not need to include the comments in parentheses:

G105 Q9 (Load Bar Stock) ; G105 Q8 (Unload Bar Stock) ;

3. If necessary, adjust the tray angle. Increase the angle if the bars do not feed reliably. Decrease the angle if the bars stack.

3.2 Bar Length Reset Procedure

If a bar feed does not complete successfully because of an EMERGENCY STOP or an alarm, the Bar Feeder can lose the current bar length and you need to reset it.

1. Enter MDI mode.

2. Press [V], and then [HANDLE JOG].

3. Use the jog handle to control the V Axis until the bar is at the reference position.

4. Type G105 Q1 ; in MDI, and then press [CYCLE START].

This resets the bar length and pushes the bar to its initial push-out length.

Chapter 4: G-Code Reference

4.1 G105 Servo Bar Command

This is the G-code used to command a Bar Feeder.

G105 [In.nnnn] [Jn.nnnn] [Kn.nnnn] [Pnnnnn] [Rn.nnnn]

I - Optional Initial Push Length (macro variable #3101) Override (variable #3101 if I is not

commanded)

J - Optional Part Length + Cutoff (macro variable #3100) Override (variable #3100 if J is

not commanded)

K - Optional Min Clamping Length (macro variable #3102) Override (variable #3102 if K is

not commanded)

P - Optional cutoff subprogram Q - Bar Feeder setup mode R - Optional spindle orientation for new bar

I, J, K are overrides to macro variable values listed on the Current Commands Page. The control applies the override values only to the command line in which they are located. The values stored in Current Commands are not modified.

When you command G105, the Bar Feeder does one of these operations, based on the length of the current bar and the value of MINIMUM CLAMPING LENGTH (#3102 or K) added to PART LENGTH + CUTOFF (#3100 or J):

G-Code Reference

1. If the current bar is long enough to correctly clamp and machine a new part (the bar is longer than MINIMUM CLAMPING LENGTH plus PART LENGTH + CUTOFF):

a) If there is a P value in the G105 block, the control runs the cutoff subprogram. b) The spindle stops.

c) The workholding unclamps.

d) The Bar Feeder pushes the bar the distance specified in PART LENGTH +

CUTOFF (#3100) or, if the G105 block has a J value, the distance specified by J.

e) The workholding clamps and the program continues.

2. If the current bar is too short to correctly clamp and machine a new part (the bar is shorter than MINIMUM CLAMPING LENGTH plus PART LENGTH + CUTOFF):

a) If there is a P value in the G105 block, the control runs the cutoff subprogram. b) The spindle stops.

c) The workholding unclamps, and the pushrod moves to the unloaded position.

d) If the G105 block has an R value, the spindle orients.

e) The Bar Feeder loads a new bar and pushes it the distance specified by

INITIAL PUSH LENGTH (#3101) or, if the G105 block has an I distance specified by I. If #3101 and I have values of zero, the Bar Feeder pushes the bar the distance specified by REFERENCE POSITION (#3112).

f) The workholding clamps.

g) If there is a P value in the G105 block, the control runs the cutoff subprogram,

unclamps the workholding, then pushes the bar the distance specified by #3100 or J, then clamps the workholding.

h) The program continues.

If the Bar Feeder cannot complete a bar feed operation because of an alarm or

[EMERGENCY STOP], the system stops and displays the message Check Bar Position. If you are confident that the bar position is correct, press [CYCLE START] to

continue. If you are not confident that the bar position is correct, refer to the bar length reset procedure on page 18.

4.2 G105 Q Modes

Q modes are special Bar Feeder commands that you use with a G105 command in MDI mode. They are generally for setup and troubleshooting purposes. This section describes the available Q modes.

To use a Q mode, type G105 QX ; in MDI mode, where X is the Q mode number you want to command, and then press [CYCLE START].

G105 Q0 - Normal Bar Feed: Use this to command a normal bar feed in MDI mode. This

is the same as a G105 command with no Q mode.

G105 Q1 - Set the Bar Length: Use this command to reset the bar length stored in the

control. You can use this for bars that are too short to load, or for recovery after an error. Press [V] and then [HANDLE JOG], then use the jog handle to push the bar to the reference position. Clamp the workholding and run this command to recalculate the bar length.

NOTE: The push rod must be in contact with the bar when you set the bar

length. If the bar is pushed out too far, jog the push rod back, push the bar against it by hand and then jog the bar to the reference point.

G105 Q2 [I] - Set the Reference Position, then Initial Push: This command sets the

reference position, unclamps the workholding and then pushes the bar the distance specified in the Initial Push Length variable (#3101), or the I value if given, then clamps the workholding. It then runs the cutoff subprogram (PXXXXX) if specified. You must

command G105 Q4 before you can use this command.

NOTE: The push rod must be in contact with the bar when you set the

reference position. If the bar is pushed out too far, jog the push rod back, push the bar against it by hand and then jog the bar to the reference point.

96-8913A.book Page 24 Monday, May 18, 2015 7:55 AM

G105 Q Modes

G105 Q3 - Set the Reference Position from the Bar Face: This command subtracts the

Part Length + Cutoff variable (#3100) from the current bar face position to set the reference position. It then runs the cutoff subprogram (PXXXXX), if specified. Refer to the description of G105 Q2 for other considerations. You must command G105 Q4 before

you can use this command.

WARNING: This command does not cause the bar to move. If you execute this

command more than once, it moves the reference position farther away from the bar face, and possibly out of the clamping area. If the bar is not clamped when the spindle starts, severe damage will occur.

G105 Q4 [R] - Jog to the Reference Position: This command loads a bar, measures it,

and then pushes it through the spindle. It stops just before the chuck face. Press RESET to use the V-Axis handle jog mode to jog the bar to the reference position.

G105 Q5 - Set the End-of-Bar position: This command sets the switch position that the

control uses to determine bar lengths. This value is stored in variable #3111. The service technician establishes this value during installation. It is necessary to reset this variable only if its value is lost.

G105 Q6 - Unload the Push Rod: This command causes the bar feeder to remove the

push rod from the bar pusher. It then lifts the push rod into the storage position.

G105 Q7 - Load the Push Rod: This command causes the bar feeder to move the push

rod onto the bar pusher.

G105 Q8 - Unload the Bar: This command causes the Bar Feeder to remove a bar from

the transfer tray and put it in the charging tray. Make sure that the bar is within the space of the charging tray before you execute this command.

G105 Q9 - Load Bar: This command causes the Bar Feeder to load a bar from the charging

tray and put it in the transfer tray.

G105 Q10 - Load Bar and Measure: This command loads a bar from the charging tray to

the transfer tray, then measures it. You use this command to check the end-of-bar switch position. Put a bar of known length in the charging tray. Command G105 Q10, and compare the actual bar length to the value in variable #3110.

G105 Q11 - Bump Load Push Rod Direction: Used for assembly access only. Bumps

the bar transfer mechanism toward the charging tray.

G105 Q12 - Bump Load Bar Direction: Used for assembly access only. Bumps the bar

transfer mechanism away from the charging tray.

Chapter 5: Programming

5.1 Program Examples

This section has (3) program examples.

• Example 1 calls a subprogram in the G105 command to cut off the part. This programming style is most appropriate for solid stock where the cutoff program must cut to the centerline.

• Example 2 includes the cutoff in the part program. This programming style is most appropriate when the finished part has a hole through the center, and the cutoff program does not have to cut to the centerline.

• Example 3 describes a double push. This programming style is most appropriate to machine a length of bar shorter than the full part length, and then push to the full part length.

Programming

CAUTION: The sample programs in this manual have been tested for accuracy,

but they are for illustrative purposes only. The programs do not define tools, offsets, or materials. They do not describe workholding or other fixturing. If you choose to run a sample program on your machine, do so in Graphics mode. Always follow safe machining practices when you run an unfamiliar program.

96-8913A.book Page 28 Monday, May 18, 2015 7:55 AM

Program Examples

5.1.1 Example 1 - Cutoff Subprogram

This example shows the preferred programming method with solid stock material, where the cutoff operation must cut to the centerline. The material is 2" (51mm) diameter solid stock and the finished part is 1" (25mm) long. The cutoff tool is 0.125" wide. The spindle/tool clearance is 0.875". The amount of stock to remove from the face is 0.025".

The program uses these Bar Feeder variable values:

Variable Number Description Value

#3100 Part Length + Cutoff Allowance + Facing Allowance 1.150

#3101 Initial Push Length 1.025

#3102 Minimum Clamping Length 1.0

Command G105 in MDI mode to load a bar and push it to the initial push length. In this example, the initial push length includes the 0.875" spindle/tool clearance, the 0.125" width of the cutoff tool, and a 0.025" facing allowance.

This program starts with a call to the cutoff subprogram. The effect of this is different depending on whether this is a new bar or if it is the next program loop on a bar:

• If this is a new bar, the cutoff subprogram faces and cleans the bar end at the initial push length (#3101), and then the Bar Feeder pushes out the part length plus allowances (#3100).

• When the subprogram call repeats on a bar, the cutoff subprogram cuts off finished parts and leaves a clean bar end, and then the Bar Feeder pushes out the part length plus allowances (#3100).

NOTE: When you write a bar feed program with a cutoff routine and then a bar

feed command, or with a bar feed command that includes a Pxxxxx cutoff subprogram call, it is safest and most consistent to start the program with the bar feed command. This practice makes sure that a fresh piece of material, with a faced surface, in a consistent position, is always available for the rest of the operation.

Program Examples

5.1.2 Example 2 - Cutoff in Program

This example shows the preferred programming method when the cutoff operation does not have to cut to the centerline, as when the finished part has a hole through the center. Unlike the first program example, which uses the same subprogram to both face a new bar and cut off finished parts, this program includes a facing operation for a new bar, and a separate cutoff operation for finished parts. The facing operation cuts to the workpiece centerline. To save machining time, the cutoff operation cuts only as far as the finished part’s inner diameter.

The material is 2" (51 mm) diameter solid stock and the finished part is 1" (25 mm) long. The cutoff tool is 0.125" wide. The spindle/tool clearance is 0.875". The amount of stock to remove from the face is 0.025".

The program uses these Bar Feeder variable values:

Variable Number Description Value

#3100 Part Length + Cutoff Allowance + Facing Allowance 1.150

#3101 Initial Push Length 2.0

#3102 Minimum Clamping Length 1.0

Command G105 in MDI mode to load a bar and push it to the initial push length. In this example, the initial push length includes the 1" finished part length, 0.875" spindle/tool clearance, the 0.125" width of the cutoff tool, and a 0.025" facing allowance.

This program starts with the face and turn operation, then the cutoff operation, and the bar feed command at the end.

Note also that the program has a block-deleted M99 command in the second-to-last line. This lets you turn on block delete if you want the program to run only (1) time.

5.1.3 Example 3 - Double Push

This example demonstrates a double push on the workpiece. The program contains (2) G105 commands. The first G105 uses the variables values set on the Bar Feeder current commands page. The second G105 uses J and K values to override the variable values.

This is the preferred programming method when, for example, you need the rigidity of a short bar for part of your operation, and then to machine the rest of the longer finished part.

The material is 2" (51 mm) diameter solid stock and the finished part is 4" (100 mm) long. The cutoff tool is 0.125" wide. The spindle/tool clearance is 0.875". The amount of stock to remove from the face is 0.025".

The program uses these Bar Feeder variable values. These values apply to the first G105 command, given without address codes:

Programming

Variable Number Description Value

#3100 Part Length + Cutoff Allowance + Facing Allowance 1.150

#3101 Initial Push Length 2.025

#3102 Minimum Clamping Length 4.0

In the second G105 command, the program uses these address codes to override the values given in the bar feeder variables:

Address Code Description Value

J Part Length + Cutoff Allowance + Facing Allowance 3.0

K Minimum Clamping Length 1.0

96-8913A.book Page 32 Monday, May 18, 2015 7:55 AM

Program Examples

Note also that the program has a block-deleted M99 command in the second-to-last line. This lets you turn on block delete if you want the program to run only (1) time.

Command G105 in MDI mode to load a bar and push it to the initial push length. In this example, the initial push length includes the 2" length to machine first and a 0.025" facing allowance.

Before you run this program for the first time after you load a bar in MDI mode, move the cursor to the block after the first G105 command in the program to bypass the first push. Remember that after the initial push, the bar is already in position to start machining.

5.2 Counter

The Bar Feeder can count either the numbers of bars used, the number of parts made, or the length of material run. A non-zero value set in Max # Parts (#3103), Max # Bars (#3104), or Max Length to Run (#3105) determines the active counting modes. The first non-zero value stops the cycle if more than one is present.

To stop the machine after a chosen number of parts, set Current Number of Parts Run (#3106) to zero. Then, set Max # Parts (#3103) to the chosen quantity. The counter increments at each G105 command. If G105 is at the beginning of the program, the counter increments before each part starts machining. If G105 is at the end of the program, the counter increments after each part finishes machining.

To stop the machine after a certain number of bars, set Current Number of Bars Run (#3107) to zero. Then set Max # Bars (#3104) to the number of bars to run. The counter increments as each bar is loaded.

To stop the machine after a certain length of bar, set Current Length Run (#3108) to zero. Then set Max Length To Run (#3105) to the total bar length you want to machine.

Programming

NOTE: The counter increments by the push distance at each G105

command. This distance is either the initial push length (#3101) after a bar is loaded or the part length + cutoff (#3100) at each bar feed after the initial push.

Loading Short Bars

5.3 Loading Short Bars

F5.2: Short Bars Must Use At Least (2) Pick Arms

To machine short bars:

1. When you load short bars on the charging tray, make sure that at least (2) of the pick arms pick the bar up, or the bar may not load properly.

NOTE: The actual minimum bar length depends on your setup. Refer to

page 11 for a description of the process to determine your minimum bar length.

2. Push all of the bars against the side of the charging tray closest to the lathe.

3. Enter the length of the longest bar in the tray into macro variable #3109 on the BAR FEEDER Current Commands page.

The bar pusher rapids to the buffer position before it slows to measure the bar length.

Chapter 6: Maintenance

6.1 Maintenance

WARNING: Press [POWER OFF] on the lathe before you do maintenance tasks.

The Haas Bar Feeder requires little regular maintenance for optimal operation.

• Apply grease to the push rod and bushing. Manually move the push rod back and forth to spread the grease and check for binding. Do this approximately (1) time per month, or when the push rod is dry.

• Approximately (1) time per month, align the grease fitting in the linear guide truck with the hole in the enclosure and apply (2) strokes from a grease gun.

Maintenance

F6.1: [1] Linear Guide Lubrication Access

• Clean the transfer tray.

• If a feed problem occurs, look for obstructions in the bar path before you continue operation. Check for wear or debris in the spindle liner, and replace it if necessary.
