1. OUTLINE

SEICOS-∑ 10L, ∑ 16T, ∑ 18T and ∑ 21L are products that have integrated the latest device technology and realized down-sizing with high reliability.

The machine is designed by giving consideration to users standpoint in the operating system as the man-machine interface, thus offers a most easy-to-operate machine.

This manual contains explanation on the operating method of the following models. As for the subject of programming, refer to “SEIKI-SEICOS∑ 10L/16T/18T/21L program part” and for subjects on alarms and maintenance to “SEIKI-SEICOS∑ 10/16/18/21 maintenance part” respectively.

Model Name	Abbreviation
SEIKI-SEICOS ∑ 10L	S-∑ 10L
SEIKI-SEICOS ∑ 16T	S-∑ 16T
SEIKI-SEICOS ∑ 18T	S-∑ 18T
SEIKI-SEICOS ∑ 21L	S-∑ 21L

1-1 Items requiring attention when reading this manual.

(1)In this manual and the reference manual “program part”, explanations are made on all the functions that are applicable to these NC machines, including optional functions. The option function selected for adoption are different for each machine. Please confirm the specification of the machine beforehand, as there may be some functions referred to in the manual are not usable depending on the machine.

(2)In this manual, those functions not specifically remarked “able” should be understood as “unable”.

(3)The contents of this manual may be changed without notice to meet a future machine

improvement.

Note)	Programs, parameters, macro variables and tool compensation amounts, etc. are stored in
	the memory of NC unit. Generally, these data are not lost by switching the power ON/
	OFF.
	Nevertheless, data could be lost inadvertently or by erroneous operation. Also a case
	may occur when you are compelled to have valuable date in the memory cleared for
	restoring the system from a trouble.
	To cope with such an unexpected situation, we suggest that you take note of the important
	data and keep them separately. It facilitates quick restoration of working condition of the
	machine by re-entering the data.
Note)	When processing a work, do not start the operation suddenly. Make a trial warm-up run
	first for fully confirming that the machine acts correctly, then proceed with subsequent
	operating procedures.

Note 1) For the Type IS-A, nothing is changed even if you set the parameter for 10-time minimum setting unit.

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 scale.

Absolute encoder will be installed for adding the optional absolute position detection function.

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 ANGLE DESIGNATION LINEAR INTERPORATION (G01)

With G01, an angle from Z axis is specified where linear interpolation is commanded.

2-4 Circular Interpolation (G02, G03)

Circular interpolation can be performed arbitrarily at 0 to 360° 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) Not available with ∑ 21L.

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......Not available with ∑ 21L.

Another axis is linearly interpolated synchronously with circular interpolation.

2-8 Polar Coordinate Interpolation

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

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 circular interpolation can be performed in combination with other linear axis.

3.THREADING

3-1 THREADING (G32)

With F or E code, a thread lead is directly commanded. With E code, you can assign the number of thread ridges per inch can be assigned by a parameter.

3-2 MULTIPLE THREADIGN (G32)

Use this to perform multiple thread cutting which has two or more thread ridges in a lead. With Address Q, command a threading start shift angle. be performed.

3-3 VARIABLE LEAD THREADING

By commanding the increase or decrease amount in lead per one screw thread turning, you can perform variable lead threading. With Address K, command a lead changing amount.

4.FEED FUNCTION

4-1 RAPID TRAVERSE RATE AND RAPID OVERRIDE

The maximum speed available in the axial direction is 240,000mm/min (IS-B). Further, override can be applied to rapid traverse by rapid override.

4-2 CUTTING FEED RATE AND FEED OVERRIDE

The maximum feed rate range available for setting is 6~240,000mm/min (IS-B). Override can be applied, by feed rate override, within a range of 0~200% by every 10%.

Table 4-2 shows the ranges of feed rate command values:

			TYPE		F COMMAND RANGE

(1)Cutting cycle A (G90) → outside/inside diameter cutting

(2)Threading cycle (G92)

(3) Cutting cycle B (G94) → end face cutting

12-3 Maltipul Fixed Cycle

Several kinds of fixed cycles are prepared beforehand to facilitate a program. With information of the finished configuration alone being given, the tool passage for rough cutting to the end is automatically fixed. A fixed cycle for threading is also available.

2 - 10

13. TOOL OFFSET FUNCTIONS

13-1 Automatic Tip R Compensation and Cutter Compensation

(1)Automatic Nose R Compensation (G143)

It is normally held at G143 (Automatic Nose R Compensation Valid Mode). Therefore, without G code not being commanded, tip R compensation is automatically executed. Nose R is set to tool compensation R and virtual nose points (1~8) to T.

(2)Cutter Compensation (G145 : G40~G42)

With G145 command, Cutter Compensation mode is created.

With G40~G42 commands while in this mode, cutter compensation can be carried out. A tool diameter is set to tool compensation R and a virtual nose point (9) to T.

13-2 Groove Width Compensation (G150 to G152)

When a grooving tool is used, one virtual tool nose (for example, 3) is used to run the program to apply compensation. It is also necessary to compensate the other virtual tool nose (for example, 4) side. When this is done, this function compensates the groove width by specifying a G-code.

13-3 Addition of Tool Offsets

The number of tool offset pairs can be expanded up to 200.

Expansion of tool offset pairs: 64/99/200 (Up to 99 pairs for the ∑ 21L)

2 - 11

15. MEASURING FUNCTIONS

15-1 Skip Function

If a skip signal is input from an external device in the midst of an X-, Y-, or Z-command following G31, the next block will be executed, canceling the rest of this command. A skip signal input position can be read with a system macro variable.

15-2 Q SETTER

Through simple manual operation with the touch sensor, tool offset volume is automatically written.

15-3 Q-setter Repeat Function

By measuring the tool with the Q-setter once, automatic measurement with the Q-setter is activated by simple operation when changing tips.

16. CUSTOM MACRO

16-1 Custom Macro

A function peculiar to the user can be created. There are 100 common variables, but their number can be optionally extended up to 600.

17. AXIS CONTROL

17-1 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.

17-2 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.

2 - 12

18. MANUAL OPERATION

18-1 Manual Continuous Feed

With the axial feed switch being pressed in Jog mode, manual continuous feed is performed.

Feed rates are as follows:

1Jog feed

Jog feed rate can be changed over into 24 stages through use of the switch. Speed in 24 stages is set with parameters.

2Manual rapid

When jog feed is executed as the rapid traverse button being pushed, manual rapid traverse is available.

18-2 Manual Pulse Generator

The machine is capable of fine feed by means of the pulse generator on the machine operation panel. One rotation of the pulse generator generates 100 pulses. You can select a scale factor of x 1, x 10, or x M (M=1 to 100 set in a parameter) by a signal from the machine.

19. AUTOMATIC OPERATION

19-1 DNC Operation

With the optional board being added, DNC operation from the host CPU is made available.

19-2 Program Number Search

19-4 Restart of Program

To restart a program, there are three ways; program restart, block restart, and machining break point return.

1Program restart is a function to restart from the block of a specified sequence number.

2Machining break point return is a function to position a tool to a break point by jog feed.

19-5 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.

19-6 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.

2 - 13

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

Function	No. of pre-reading blocks
Automatic tip R compensation	4 blocks
Multi buffer	12 blocks
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,

G10, G20, G21,

M00, M01, M02, M30

T Command

Note 3) As the automatic tip R compensation is normally held valid (G143 mode), pre-reading of 4 blocks is carried out.

(2)When the SINGLE BLOCK switch is turned on

(State in which automatic tip R compensation is held invalid : G140, G145 mode) 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) Pre-reading is performed when any of the following applies:

(a)In Multi Buffer mode (G251)

(b)Tool radius compensation mode (G41, G42)

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

(d)Thread cutting (G32)

(e)Tapping mode (G63)

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

19-7 Feedhold

All axes can be stopped temporarily. Pressing the CYCLE START button restarts feeding the axes. Prior to restarting axis feed, you can allow intervention by manual operation in the manual mode.

2 - 14

19-8 External Reset and Reset Signal

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.

20-3 Single Block

Program commands can be executed block by block.

20-4 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. When, on start of pre-machining plotting, an interlock signal, etc. to stop interpolation has been made effective, pre-machining plotting is stopped with the corresponding command.
