2 Sequence of Operations	04/2005
2.1 Powering-up the control

2.1 Powering-up the control

Unless the machine manufacturer has set it up differently, the controller powers up automatically when the power supply is switched on. Internal test routines are performed during the power-up process. Once they have been successfully completed, the controller opens and displays the Reference Point screen form.

2.2 Reference point approach

Once the controller has powered up, the Reference Point screen form appears:

Fig. 2-1: Reference point approach

!Note

Before starting the reference point approach, be sure to move the machine slide to a position from which the reference point can be approached in a positive axis direction.

2.2.1Preparations for reference point approach

Before you can approach the reference points for the two axes, the following conditions must be met:

Prerequisite

•There must be no NC alarms pending!

→Clear any that are pending by pressing the "Reset" function key.

•All machine axes must be in a position from which the reference point can be reached in a positive traversing direction.

→In manual mode, use the handwheels to move the axes to the appropriate position ahead of the reference point.

2.2 Reference point approach

Caution

In this operating mode the axes can only be approached using the handwheel. Use of the 4-way switch or axis direction keys to move the axes is blocked. In addition, the spindle cannot be started in this mode.

•Press the “Refer. Axes” function key to switch back to “Reference point approach” mode.

2.2.3Reference point approach

Displays

Axis has not yet been referenced

Axis has already reached the reference point (is referenced)

Once all the conditions have been met (→ Preparations for reference point approach), reference point approach can be started for each axis as follows:

•Using the 4-way switch or axis direction key, start the X axis in the positive direction (X+). The reference point for the X axis is then approached automatically.

•At the end of this process the axis stops automatically and the symbol is displayed in front of the axis name.

•Once the X axis has reached its reference point, the same process can be repeated for the Z axis (Z+).

!Note

The axes must be referenced in this sequence, i.e. the X axis first, followed by the Z axis. Any other sequence will not be accepted by the controller.

Caution

If the machine manufacturer has not fitted an axis limit switch, there is a risk of a mechanical collision if the axis is on the wrong side of the reference point cam before the start of the reference point approach.

→ Preparations for reference point approach.

•Press the "End Refpkt." function key once both axes have been referenced to return to the main "Manual Machining" screen.

2.3 Manual Machining

The main Manual Machining screen looks like this:

Fig. 2-4: Main "Manual Machining" screen

Manual workpiece machining is carried out in this operating mode.

Here the cross-slide is controlled either

•By means of the handwheels for the X and Z axis (→ Machining with the handwheels) or

•By means of the 4-way switch or the axis direction keys (X+/X-/Z+/Z-) (→ Machining with the 4-way switch/axis direction keys)

The spindle is controlled by means of

•The spindle joystick or the individual spindle advance and spindle reverse keys (→ Spindle advance/reverse).

Machining technology data such as spindle speed, cutting speed and feedrate must be set via special screen forms.

→Machining technology data.

!Note

Generally speaking the relevant machining technology data must be entered before starting manual machining.

Caution

The maximum permissible spindle speed, which depends on the chucking device fitted, must be entered in the Machining Technology Data screen form!

Failure to pay sufficient attention to this point can lead to serious damage as a result of the chucking device speed being exceeded.

→ Machining technology data.

2 Sequence of Operations	04/2005
2.3 Manual Machining

2.3.3 Machining with the handwheels

The handwheels for the X and Z axis are not mechanically connected to the feed screws. Electronic pulse generators mounted on the handwheels generate the information needed by the controller to execute the required traversing movement.

The handwheels are only active when the 4-way switch is in the zero position and the individual axis control keys are disabled.

The distance traversed per handwheel pulse depends on the handwheel valuation setting.

→Handwheel valuation setting.

!Note

If the handwheel valuation is set to "0" or if the feedrate override switch is in the "0" position, the handwheels are disabled.

2.3.4Handwheel valuation setting

Press the “Toggle key for handwheel valuation” in the main “Manual Machining” screens to set the handwheel valuation.

The current setting will appear on the top-right of the screen (e.g., 100 INC).

If you are unable to adjust the handwheel valuation setting, it will be because the controller's internal mode is incompatible with this process. Press the “JOG” key once to resolve the problem.

Caution

An incorrect handwheel valuation setting can result in damage to the workpiece, tool and machine.

2.3.5 Machining with the 4-way switch/axis direction keys

The axis can be traversed in the desired direction by turning the 4-way switch or pressing the appropriate axis direction key. The feedrate at which the axis is traversed depends on the settings in the Machining Technology Data screen form.

The axis feedrate is also influenced by the feedrate override switch setting and, depending on the option selected in the Machining Technology Data screen form (Rev. feedrate/cutting speed), by the spindle override switch.

04/2005	2 Sequence of Operations
	2.3 Manual Machining

If rapid traverse overlay is also actuated, the axis is moved at the maximum possible speed unless a different value has been set at the feedrate override switch.

!Note

If the feedrate override switch is set to "0", any type of axis movement is blocked. With the "Rev. feedrate" and "cutting speed" settings, the feed is blocked until the spindle reaches the setpoint speed.

2.3.6Spindle advance/reverse

The spindle is started in the appropriate direction (spindle advance/reverse) by moving the spindle joystick or actuating the corresponding spindle direction key, provided that the chuck guard switch is enabled (chuck guard closed).

!Note

The spindle cannot be started unless the chuck guard switch is enabled. → Close the chuck guard.

Caution

Handling the chuck guard/chuck guard switch can lead to injury or mechanical damage and should be avoided.

When the spindle is switched off it brakes and comes to a halt. If a spindle brake is fitted, it is applied. If there is no spindle brake or it is switched off, the spindle can be rotated freely once it has stopped.

If "Spindle Positi." is selected in the "Spindle Positioning" screen form, the spindle is moved to the specified position after being switched off.

The spindle brake, if fitted, is then applied. → Spindle positioning.

The programmed spindle speed can be controlled by means of an appropriate spindle override switch setting (e.g. 50%).

2.3.7 Jog spindle

The jog spindle key (if provided by the machine manufacturer) can be used to rotate the spindle at low speed, for example to move a workpiece to a specific angular position.

2.3 Manual Machining

2.3.8 Tool change

In the case of conventional/cycle-controlled machines of this order of magnitude, with just a few exceptions, a manual tool change will generally be required. For this reason, the correct tool number (tool compensation) must be notified to the control by hand once the real tool change has taken place at the machine.

This is done as follows:

•Press function key "T" in the main Manual Machining screen form.

•The entry field for the T value is highlighted.

•Use the numeric keypad to enter the required tool number (tool offset) (permissible values 1-15).

•Press "Enter" to complete the process.

If no further messages appear, the controller has completed the tool change.

!Note

The tool number (tool offset) can only be changed, if all axes and the spindle are stationary.

Caution

The tool number (tool offset) entered in the T value field must correspond to the tool fitted in the machine. Otherwise, the tool will have to be re-calibrated (→ Tool calibration). An uncalibrated or incorrectly calibrated tool can lead to dimensional errors or to incorrect cutting values.

If machining technology data settings for the tool number (tool offset) to be activated are found in the “Tool Data” screen form (→ Entering tool technology data), the following message appears (relating to T4, in this example):

Fig. 2-6: Tool technology data acceptance message

The question can be answered by pressing one of these function keys:

"OK"	The tool offsets for the X and Z axis corresponding to the last tool
	calibration operation are applied. The actual-value display changes,
	if necessary.
	The previous machining technology data is also overwritten by the
	tool technology data (which has been saved for this tool) (feedrate,
	spindle speed, cutting speed)
	→ Entering tool technology data.
“Abort”	The tool offsets for the X and Z axis corresponding to the last tool
	calibration operation are applied. The actual-value display changes,
	if necessary.
	The previous machining technology data is retained.

2.3.9 Machining technology data

Machining technology data, such as spindle speed, cutting speed and feedrate, defines the settings that the controller needs for the machining of workpieces.

!Note

The machining technology data can only be changed, if all axes and the spindle are stationary.

There are two ways of changing the machining technology data:

•Simple changes to the spindle and feedrate values (S value/F value) can be made directly in the "Manual Machining" screen form.

→ Changing the spindle/feedrate value

2.3.10 Changing the spindle/feedrate value

This method of adapting technology data can be used to change values quickly during machining.

The values are changed using the appropriate function keys in the "Manual Machining" screen form.

However, it is not possible to switch between "m/min" and "rev/min" (spindle) or "mm/min" and "mm/rev" (axis) here (→ Entering machining technology data).

Changing	Press function key "S" to highlight the display field showing the
the S	current programmed spindle value. The programmed value can now
value:	be changed via the numeric keypad. Then press Enter to accept
	(activate) the change. The entry field is deselected and the process
	is complete.
	To abort the change, press function key "S" or the Alarm reset key
	instead of Enter. In this case the entry field is again deselected, the
	new value is cleared and the previously programmed spindle value
	is restored.
	You cannot switch between "m/min" and "rev/min" here.
Changing	Press function key "F" to highlight the display field showing the
the F	current programmed feedrate value. The programmed value can
value:	now be changed via the numeric keypad. Then press Enter to
	accept (activate) the change. The entry field is deselected and the
	process is complete.
	To abort the change, press function key "F" or the Alarm reset key
	instead of Enter. In this case the entry field is again deselected, the
	new value is cleared and the previously programmed feedrate value
	is restored.
	You cannot switch between "mm/min" and "mm/rev" here.

!Note

The S value or F value can only be changed if all axes and the spindle are stationary.

	2.3 Manual Machining

2.3.11 Entering machining technology data:

To open the screen form for machining technology data, press the "Spindle" function key in "Manual Machining".

The following screen form appears:

Fig. 2-7: Machining technology data input

When the screen form appears, the last entry field to have been edited is highlighted and a new value can be entered. To change a value in a different entry field, use the cursor keys to move to that field. Enter the value via the numeric keypad and then press Enter to accept (activate) the value. To abort the change and restore the previous entry value, use the cursor keys to move to a different entry field or exit the screen form (by pressing the "Back" function key), without pressing Enter.

The meanings of the individual entry fields are defined as follows:

Const. Spindle	This entry value defines the programmed spindle speed for
Speed	machining with "Spindle speed + Time feed" or "Spindle
	speed + Rev. feedrate". The value is only fully reached if no
	reduction is specified via the spindle override valuation or the
	spindle speed limit parameter ("Max. spindle speed").
Const. cutting	Cutting speed entry value for machining with "Cutting speed +
Speed	Rev. feedrate". The spindle speed is adjusted to the
	machining diameter of the workpiece so that uniform cutting
	conditions are achieved. Since the spindle would theoretically
	have to rotate at an "infinitely high" speed at the rotational
	center point in this mode, it has to be limited via the "Max.
	spindle speed" parameter. The constant cutting speed can
	also be influenced by means of the feedrate and spindle
	override valuation settings.

2.3 Manual Machining

Max. spindle	It is vital to enter the maximum permissible spindle speed
speed	here. The spindle speed is then limited to this value under all
	circumstances, so that the permissible chucking device
	speed, for example, cannot be exceeded.
Time feed	If Time feed is selected, the axes are moved at the speed
	entered here (mm/min) (unless rapid traverse override is
	activated). It can be influenced by the feedrate override
	switch setting.
Feedrate per	The value entered here determines the axis velocity in
rev.	“Spindle speed + Rev. feedrate” or “Const. cutting speed +
	Rev. feedrate” modes (if no rapid traverse override is set). It
	is influenced directly by the feedrate override valuation setting
	and indirectly by the spindle override valuation setting.

Caution

In the entry field for the maximum permissible spindle speed, you must enter the value specified by the manufacturer for the chucking device that is fitted! Failure to pay sufficient attention to this point can lead to serious damage as a result of the chucking device speed being exceeded.

•To select the desired machining mode, press the "Spindle Feed" function key one or more times:

"Spindle speed + Time feed" → "Spindle speed + Rev. feedrate" → "Cutting speed + Rev. feedrate"

The symbols displayed next to the text have the following meaning:

Display:	Machining mode deselected
	Machining mode active (selected)

2.3.12 Spindle positioning

The Spindle positioning function is intended purely for stopping the spindle in a specific position to facilitate fitting of the chuck guard. It is not intended for positionrelated machining.

If the Spindle positioning function is selected, the spindle is switched off and then moved to the position specified in the "Set spindle pos." entry field. If fitted, a spindle brake is then applied.

To open the “Spindle Positioning” screen form, press the "Spindle Positi." function key in the "Machining Technology Data" screen form.

The following screen form appears:

Fig. 2-8: Spindle positioning

When the screen form appears, there are two ways to enter the position:

•Use the numeric keypad to enter the position directly in the highlighted entry field for the "Set spindle pos.". Then press Enter to accept the value. Only values from 0 to 359.9 are permitted; otherwise, an error message appears and the value is not accepted.

•After switching off the spindle, rotate it manually into the required position and press Enter. The current spindle position is displayed in the "Set spindle pos." entry field and automatically accepted. If the spindle has not completed a full rotation since the controller was last powered up, the spindle is not yet synchronized and the position will therefore not be accepted. In this case, a corresponding message is displayed.

3.1 Tool list

3.1 Tool list

The controller is supplied with a tool list for 15 tools as standard. However, the individual tools must be calibrated prior to initial use.

→ Tool calibration.

Caution

An uncalibrated or incorrectly calibrated tool can lead to dimensional errors or to incorrect cutting values! If the values entered are very different from the actual tool values, there is a risk that the tool may break or the mechanism or workpiece may be damaged.

To open the "Tool Data Overview", press the "Tool" function key in the main "Manual Machining" screen form.

The following screen form appears:

Fig. 3-1: Tool data overview

The active offsets for each tool, known as the tool offsets for the X and Z axis, are displayed in this screen form. Experienced lathe operators can use this screen form to enter the tool offsets, as on CNC controllers. Other operators should simply refer to this screen form for information about the current offsets. The actual tool measuring process takes place in the "Tool Measuring" screen form.

→ Tool calibration.

Data can be entered in the "Tool Data Overview" as follows:

•Use the cursor keys to select the required field (field is highlighted)

•Select the required tool type (turning tool or drilling tool) by pressing the "Turn-/Boretool" function key

•Enter the values and press Enter to accept. The actual value display on the machine (in "Manual Machining") is now updated to reflect the change. If you do not wish to accept the value entered, either use the cursor key to leave the entry field or switch to another screen form without pressing Enter.
