I am trying to write a program for a part that will be repeated in a grid pattern I am trying to use the multiple machining code g62. The manual says I can make a subroutine modal and can repeate it using G62 but I don't see where it says how to do that. here is what I have so far:


G00 Z3.00000
G00 X5.89375 Y16.32500
G01 Z-0.25 F200
G01 X6.89375 Y16.32500
G01 X5.89375 Y16.32500

G62 X35.2125 I12.2724 Y65.7 J16.425

G00 Z3.00000
G00 X2.70625 Y2.90625
G01 Z-0.75 F200
G01 X10.08125 Y2.90625
G01 X10.08125 Y14.96875
G01 X2.70625 Y14.96875
G01 X2.70625 Y2.90625

G62 X35.2125 I12.2724 Y65.7 J16.425

I've never used G62 but this may help.

1. Move the tool to start position.
2. Define the sub. eg(Sub(222))
3. Define the multiple operation.

G00 Z3.
G00 X5.8937 Y16.325
G01 Z-0.25 F200
G01 X6.8937 Y16.325
G01 X5.8937 Y16.325
(Sub(222))
G62 X35.2125 K3.? Y65.7 D4.
------------------------------------------------
Save as Program 222
(These figures increments?)
G91
G00 Z3.00000
G00 X2.70625 Y2.90625
G01 Z-0.75 F200
G01 X10.08125 Y2.90625
G01 X10.08125 Y14.96875
G01 X2.70625 Y14.96875
G01 X2.70625 Y2.90625
G90

The program should cut a key hole slot and an outside perimeter. It should cut 20 parts in a 4x5 grid pattern. After reading the manual a little more I think the following might be correct. I am not at my machine right now. If any one has suggestions to do this better I am open.

Hi My thoughts are that Block G62 X35.2125 I12.2724 Y65.7 J16.425 should be G62 X35.2125 I8.8031 Y65.7 J21.9 or G62 X35.2125 K5. Y65.7 D4.
Pic attached of how I think the grid pattern is?
Also I think the subs should be G91 ( incremental )
Just my 2 cents worth.

[Kiwi]

This may also be the layout??
All a bit of a guessing game with limited information.

[Kiwi]

...... If any one has suggestions to do this better I am open.......

Here is another possibility?
A little feed back may help.

[Kiwi]

Here is another possibility, surely one of these is correct.

Here is the pattern I am trying to do. This is the code for just the key hole slot up top. it will do the first cut move to the position of the second cut move back to the position of the first cut and then do the fist cut again. so it will move to the position of every cut but move back and repeat the first cut every time. I tried to make the sub incremental but it did some strange things also.

Your code G62 I11.7375 K4 J16.425 D5 doesn't appear to match the Y dimensions on your drawing.
