1. OUTLINE

The SEIKI-SEICOS Σ 10M/16M/18M has realized a miniaturized high-reliability system by integrating up-to-date device technology. TheΣ 10M/16M can perform high-speed, highaccuracy machining, using 64-bit RISC (Reduced Instruction Set Computer).

The operation system as a human interface is designed very user-friendly from a perspective of the user. For example, a canned cycle editing function is provided as an option in order to facilitate editing of canned cycles.

This manual describes how to operate the following models.

See “SEIKI-SEICOS Σ 10M/16M/18M-PROGRAMMING” for programming, and “SEIKI-SEICOS

Σ 10/16/18/21” for alarms and maintenance.

Model	Designation
SEIKI-SEICOS Σ 10M	S-Σ	10M
SEIKI-SEICOS Σ 16M	S-Σ	16M
SEIKI-SEICOS Σ 18M	S-Σ	18M

1-1 Precautions for Reading This Manual

(1)This manual and SEIKI-SEICOS SΣ 10M/16M/18M-PROGRAMMING describe the entire functions of this NC unit, including the optional functions. The selected functions vary from one machine to another. As some of the functions described in the manual are not available, check the specifications of the machine beforehand.

(2)When there is any function not described “possible” in the manual, take it “impossible.”

(3)The information herein is subject to change without prior notice.

CAUTION

The programs, parameters, macro variables, and tool offset amounts have been stored in the internal memory of the NC unit. Generally, they are not lost by turning on/off the power. They may be erased by mistake or you are forced to erase the precious data saved in the memory in order to recover from a failure.

Make back-up copies of various data in advance so that you can quickly recover from such an unexpected incident.

CAUTION

Before starting machining, be sure to fully confirm proper operation of Machine by performing a trial run.

Before using work coordinate data and tool offset data, be sure to confirm that the data have been properly input.

1. CONTROLLED AXES

1-1 Controlled Axes

The 3 axes, X, Y and Z, are controllable. Furthermore, up to 8 axes can be controlled by adding the optional 5 axex; 4th through 8th axes.

1-2 Simultaneous Controllable Axes

The 3 axes, X, Y and Z, can be controlled simultaneously regardless of rapid traverse or cutting feed. Furthermore, up to 8 axes can be controlled simultaneously (option). Table 1.2 shows the configuration of the controlled axes.

Table 1-2

	No. of Axes	Axis Name	Remarks
Standard	3 axes	X, Y, Z
controlled axes
Additional axes	5 axes	Select of of U, V, W, A,
control		B and C
Simultaneous	Standard 3 axes +	All the axes specified by
controllable axes	additional axes	the system
		(up to 8 axes)

(Note 1) The number of controlled axes, and relations between the axis names and axes can be selected with prameters.

1-3 Increment System

There are two types of increment systems; IS-B and IS-C. You can select either of them by a parameter. (Is-A is not available for the moment.)

Millimeter/inch switching is set with a parameter. For detailed description of parameter, refer to “Parameters”.

1-4 Maximum Commandable Value

Table 1.4 shows the increment systems and commandable values.

1-6 Position Detector

The pulse encoder is provided as a standard position detector. Optionally, the pulse scale or the Inductosyn detecting function can be selected. When the Inductosyn detecting function is selected, however, you need a converter which serves as an interface equivalent to the pulse scaler.

When adding an option for detecting an absolute position, an absolute encoder will be attached.

2 - 3

2. INTERPOLATING FUNCTIONS

2-1 Positioning (G00)

Each axis can be fed at a rapid traverse rate independently by specifying G00.

2-2 Linear Interpolation (G01)

Linear interpolation is performed at the feed rate specified by an F-code in a G01 command.

2-3 Single Direction Positioning (G60)

Since this function allows precise positioning with backlash excluded, positioning can be performed from only one direction.

2-4 Circular Interpolation (G02, G03)

Circular interpolation can be performed arbitrarily at 0 to 3600 at the feed rate specified by an F-code in a G02 or G03 command.

2-5 Radius Designation on Arc (G02, G03)

R can be directly specified as a circular arc radius value, assuming I, J, and K to be a vector amount from a start point to the center in circular interpolation.

2-6 Sine Curvilinear Interpolation <Virtual Axis Interpolation> (G07)

By performing interpolation without moving one axis within a circular arc plane (hypothetical axis) in a helical cutting command, sine curvilinear interpolation is performed between the remaining two axes.

2-7 Helical Cutting (G02,G03)

Another axis is linearly interpolated synchronously with circular interpolation.

2-8 Polar Coordinate Interpolation (G120,G121)

A command programmed in the orthogonal coordinate system is converted into a linear axis move (tool) and rotary axis move (work rotation) to control a profile.

2-9 Cylindrical Interpolation (G271)

If a linear axis stroke and rotary axis angle are specified by a program command, the rotary axis stroke internally specified in terms of angle is converted into a distance on the circumference. As the distance on the circumference can be regarded a linear axis stroke on the circumference, linear interpolation and cirfular interpolation can be performed in combination with other linear axis.

3.THREAD CUTTING

4.FEED FUNCTIONS

4-1 Rapid traverse Rate and Rapid Traverse Override

The speed in the axial direction is allowed up to 240,000 mm/min (IS-B).

An override can be applied to a rapid traverse rate by rapid traverse override.

4-2 Cutting Feed Rate and Feed Rate Override

A feed rate is allowed from 6 to 240,000 mm/min (IS-B).

Feed rate override allows you to apply an override in an increment of 10% from 0% to 200%. Table 4-2 shows the feed rate command value range.

Table 4-2

		Type	F-command Range
Feed per	Metric input	F60	F1~F999999 mm/min
minute(G94)
		F61	F0.1~3F999999.9 mm/minmin
		F62	F0.01~F999999.99 mm/min/min
	Inch input	F51	F0.1~F99999.9 inch/minn
		F52	F0.01~F99999.99 inch/min
Feed per	Metric input	F32	F0.01~F999.99 mm/rev
revolution (G95)
		F33	F0.001~F999.999 mm/rev
	Inch input	F23	F0.001~F99.999 inch/rev
		F24	F0.0001~F99.9999 inch/rev
Threading (G33)	Metric input	F35	F0.00001~F999.99999 mm/rev
		F26	F0.000001~F99.999999 mm/rev
	Inch input	F26	F0.000001~F99.999999 inch/rev
		F17	F0.0000001~F9.9999999 inch/rev

(Note 1) The type can be selected with a parameter.

(Note 2) The cutting feed rate is a command given relative to the reference axis.

(Note 3) The maximum cutting feed rate is limited by the cutting feed clamp rate set with a parameter.

(Note 4) When an F1-digit feed option is added, F1-F9 have special meanings.

2 - 5

[Related Parameters]

No. 1003, #0 Sets the type IS-A, IS-B or IS-C. #1

#2 = 0 Disables the input increment 10. Enables the input increment 10.

No. 3401, #0 = 0 Specifies F23 for feed per revolution in inches. 1 Specifies F24 for feed per revolution in inches.

#1 = 0 Specifies F32 for feed per revolution in millimeters. 1 Specifies F33 for feed per revolution in millimeters.

#2 = 0 Specifies F51 for feed per minute in inches. 1 Specifies F52 for feed per minute in inches.

#3 = 0 Specifies F60 for feed per minute in millimeters. 1 Specifies F61 for feed per minute in millimeters.

#4 = 0 Specifies F26 for threading lead in inches. 1 Specifies F17 for threading lead in inches.

#5 = 0 Specifies F35 for threading lead in millimeters. 1 Specifies F26 for threading lead in millimeters.

#6 = 0 Feed per minute of 0mm abides by #3. 1 Feed per minute of 1mm for F62.

4-3 Override Cancel

A cutting feed override rate can be fixed at 100% by a signal from the machine.

4-4 Automatic Acceleration/Deceleration

Linear acceleration/deceleration is performed in case of rapid traverse, and exponential function type acceleration/deceleration is performed in case of cutting feed or jog feed.

4-5 Dwell (G04)

Migration to operation in the next program block can be delayed by a specified time by a G04 command. Use P, X, or U for an address.

4-6 Exact Stop Check (G09)

In the block where G09 is specified, an imposition check is made at the end of block execution.

4-7 Exact Stop Check Mode (G61)/Cutting Mode (G64)

Normally, the G64 mode is effected and the program proceeds to the next block immediately after interpolation is completed. If G61 is specified, the program will proceed to the next block after entering imposition at the end point of each block, in the subsequent move commands. The G61 mode is cancelled by specifying G64.

2 - 6

4-8 Automatic Corner Override (G62)

An override is applied automatically to a cutting feed rate at a corner during tool diameter compensation.

5. REFERENCE POINT

5-1 Reference Point Return A (G27 to G29)

Reference point return a includes the following:

(1)Manual reference point return

(2)Reference point return check (G27)

(3)Automatic reference point return (G28)

(4)Return from the reference point (G29)

5-2 Reference Point Return B (G30)

2 - 12

13. TOOL OFFSET FUNCTIONS

13-1 Tool diameter Compensation (G40 to G42)

A tool diameter can be compensated by specifying a G-code command, G40 through G42. An offset number can be set by a D-code, set by the lower 4 digits of a T-code, or selected, depending on parameter setting.

13-2 Tool Length Compensation (G43, G44, G49)

A tool position can be offset (tool length compensation) by a G43/G44 command. An offset number can be set by an H-code, set by the lower 4 digits of a T-code, or selected, depending on parameter setting.

13-3 Tool Offset (G45 to G48)

18. AXIS CONTROL

18-1 Follow-up Function

In case of emergency stop or servo alarm, a machine travel amount is reflected on an NC unit internal position. For this reason, automatic operation is enabled after resetting the emergency stop or servo alarm, even if you do not have to perform zero point return.

In case of speed feedback or position feedback alarm, however, an actual machine position and the NC unit internal position do not match, because the follow-up function does not work properly.

2 - 14

18-2 Mirror Image

This function can reverse the sign of the travel direction specified by a program command or MDI command for the X-, Y-, Z-axis, or an additional axis. Make this setting in the setting screen.

+ Machining break point return is a function to position a tool to a break point by jog feed.

2 - 15

20-5 Sequence Number Comparison and Stop

If you encounter the block of a preset sequence number during program execution, the machine stops after executing that block.

20-6 Preread Buffer

In order to avoid discontinuation of the program blocks at the time of cutting due to the processing time of the NC unit, the preread buffer generally prereads one program block in case of automatic operation.

(1)The preread buffer prereads the different number of program blocks, depending on the function.

Function	No. of Preread Blocks
Multibuffer	14 blocks
High-accuracy profile control	Up to G05 P0 block
Tool diameter compensation	2 to 4 blocks
Others	0 or 1 block

(Note 1) In the tool diameter compensation mode, the preread buffer prereads up to 4 blocks if they contain the blocks free from an axis move command.

(Note 2) The following commands suppress the preread buffer.

Example: G28, G30, G31, G53, G05, G10, G20, G21, G22, G23, M00, M01

(2)When the SINGLE BLOCK switch is turned on

When the SINGLE BLOCK switch is turned on and the program blocks are executed sequentially by pressing the CYCLE START switch, the preread buffer does not exist. Because, when the CYCLE START switch is pressed, one program block is taken into the

preread buffer and executed immediately. Therefore, the preread buffer does not exist during and after execution.

(Note 1) The preread buffer prereads the program blocks in the following modes.

(1)Tool diameter compensation mode (G41, G42)

(2)When optional angle chamfering corner R is specified (, C, R)

(3)Thread cutting (G33)

(4)Tapping mode (G63)

(5)High-accuracy profile control (G05 P10000)

(Note 2) When the SINGLE BLOCK switch is turned from OFF to ON during automatic operation to stop it, the preread buffer exists.

20-7 Feedhold

2 - 16

20-8 External Reset and Reset Signal

The NC unit can be reset from the outside. A reset cancels all the commands and decelerates the machine to a stop. A reset signal is output to the machine while the RESET button of the MDI & CRT panel is being pressed, the machine is being reset by an external reset signal, or the EMERGENCY STOP button is being pressed.

20-9 Override Memory and Automatic Override

When performing trial cutting, an overrides (feed override/spindle override) according to the machining conditions is memorized for each tool. At the time of machining, the abovementioned memorized override is reflected automatically, not the override rate selected at the operation panel.

20-10 Data Server

A large-capacity program can be processed at a high speed by means of the Ethernet controller and the hard disk of the auxiliary storage unit. (For details, see SEIKI-SEICOS Σ DATA SERVER INSTRUCTION MANUAL, FTP TYPE)

21. PROGRAM TEST FUNCTIONS

21-1 Machine Lock

In the machine lock mode, the machine does not move, but the position display is updated as if the machine were moving. Z-axis command cancel becomes equivalent to when a machine lock is applied only to the Z-axis.

This is effective when checking the contents of the machining data by pen-writing.

When the machine lock is turned ON→ OFF in auto operation, Machine is shifted by the amount moved by the machine lock.

21-2 Dry Run

If the DRY RUN switch is turned on, the machine operates at a jog feed rate instead of a programmed cutting feed rate. This function can be also enabled in case of rapid traverse by parameter setting.

21-3 Single Block

Program commands can be executed block by block.

21-4 Pre-Machining Plotting

In pre-machining plotting, as machine performs synchronous plotting while in auto running in machine lock and dry run state, format failures and erroneous coordinate commands, if any, in a program can be easily detected.

26-4 Stored Stroke Limit 1

Stored stroke limit 1 assumes the outside of the area set by a parameter to be a prohibited area.

26-5 Stored Stroke Limit 2 and 3 (G22, G23)

Use this function when you want to ensure that a tool will not enter a non-cutting area. Both stored stroke limit 2 and 3 assumes either inside or outside of the set area to be a prohibited area, based on parameter setting. This function is enabled or disabled by a G-code command.

G22 : Enabled

G23 : Disabled
