Need Help!- Programming a series of holes!

[Robert_Downs]

Hi guys

I need help programming a plate am working on just now, i can upload a drawing of this plate and the sizes but its just i cant get anywhere with it because there is so many holes to input, can someone write a program out for me that i can just copy to my bridgeport?

Thasnks alot

[gus]

and the control would be........?

Looks like a meatmincer plate?
Complicated arrays just aren't simple.

You either need a CAM program, or learn how to program.

All the holes are in straight lines and are equally spaced,so one way is to write a subroutine that you specify the start point, and the number of holes in the row and the step to the next hole.
When all that is done you you write a higher level program that figures out the start points.

That's how I did it 15 years ago, with no CAM software.
Once the start point is specified, you the subroutine can use incremental amounts for the step, and a counter for the number of holes, or you you can absolute like used here.
The subroutine needs turns off incremental when done otherwise it becomes confusing.

Is it stainless steel? I imagine so, and you need to run the same program with a center drill first before you start drilling.
Once you read the manuals and learn how to program it just gets easier.

This program was for a larger plate than your program, very similar number of holes.!!!!!!!!!!! Geez, I thought I was done with that job.!!

With all those holes you probably need a method with lots of M1s so you can set optional stop when the drill sounds like it needs changing.
I used 2 drills, and while one was running, sharpened the spare.
Or you could use replaceable drill tips like Iscar have.
This was using a BOSCH CC120 controller, but if you print this out and read it you should be able to figure how I did it.

BSRPxx is subrountine call. The subroutines are after N142
BEQP32 is Branch if equal to $32
All the $XXs are labels for branching.
Vxx is a variable name.
TSTVx tests the variable before a conditional branch.

Where it says SWITCH OFF, the machine had a test to see oif an option switch was on or off. G23 Pxx is where the switch is tested.
This is how the operator interacted with the program.

This didn't use G83 drill cycle, but that would be the better way to do chip-breaking. N324 is where the hole is drilled.

As you see it is the deepest nested part of the program.

I can answer the odd question to clear this up but after not doing it for 15 years, nor having any emulation software, I can't write it for you.

At a guess this drill 564 holes using about 400 lines of code.
Center drilling, 6.8mm hole, then 8mm and 12mm, or there may have been all three different hole sizes.
Can't remember too much. It just worked, and the operator followed the prompts.

When posing questions like this it really does help if you give the forum the facts needed - after all you are asking strangers (NOT MATES !!!!) to help you and spend their time solving your problem.

There are .PDF to .DXF converters out there, then verify dimensions and adjust the numbers to match, load the circles in a cam system and go. two hours cad labor.

[christinandavid]

I'd program the top 60deg sector of 90 holes then rotate the program and repeat it. You could save initial programming time doing each row of holes as an incremental loop, but I would actually put each individual co-ordinate in to give more flexibility for restarts should the tools need touching-up or replacing mid-program.

[gus]

you have rotate, lbl call angular moves at your disposal. You have a very inconvenient pattern as I cannot pick up the repeats in it quickly

[awemawson]

There is a program called plantincnc intended for pcb making, that will take your source file and locate the holes and give you co-ordinates - it will also give you G code to drill them if you wish.

PlatinCnc home


I have used it (actually on a Bridgeport Interact as it happens) where I scanned the image of a complex gasket that I needed multiples of, and made a stack of them. Worked a treat.

[gus]

something like

X0 Y122.309
CYCLE CALL
CALL LBL 1
CALL LBL 1
L X-? Y115.514
CALL LBL 1
CALL LBL 1
....


LBL 1
IX 7.846
CYCLE CALL
LBL 0
STOP
STOP
STOP

you cna only call a label with a rep of more than zero once, there is a workaround, put the lbl at the end , because when you screw up lbl repeats, it blows through lbl 0 with unpredictable results. Create 6 labels that all say:

LBL 2[and 3 and 4 and 5]
CALL LBL 1
LBL 0
STOP
STOP

don't forget the stops in case it doesn't work


if ther is no reason for this particular pattern, redraw it with a series of concentric holes and you can write the whole plate with like 20 lines of code total

LBL 2
