Hello

Few months ago the company I work for purchased a Okuma multis 400. We have ran many diff parts with full bolt holes using a fixed cycle. Now we have a few jobs comming up with partial bhc.

Was wondering if there is a fixed cycle to do partial bhc on Okuma? What we have done in the past is move tool to postion then just change the C axis for each new hole postion. What we r looking for is a one line command that we could just dump in the bhc size, number of holes, hole depth, and start angle?

Any help would be great. An example of what we would be doing is something like this. bhc=11 inches
number of holes= 8
starting angle = 10 deg
hole depth= .750

Thanks in advance

There should be a way to define which holes to skip on a BHC.

Or the other option is to place holes on an arc.

These options are in the MC4VAE Mill I run - but it does have User Task II and IMAP (IMAP just gives you graphical programming assistance for each cycle.)

I don't have a manual handy or I'd look it up for you.

What model is the control? Do you have User task I/II? I think there is a cycle for the P100 and P200 controls, but until I know, I can't look.

Okay, I am not sure for the lathe controls, but on the mills from E100-P200 the command for skipping holes is "OMIT". It must be specified before the callout of the BHC command. So if you want to skip hole #3 and #7, it would look something like this;
G81 G56 H04 R1. Z-1. F10.
OMIT R3 R7
BHC X0 Y0 I5. J45. K8.
Again, this will work on the mill controls, since you are on a lathe, I make no promises!

Hello thanks for the replies

We have user task 2 on the machine,

Barks,
If I remember correctly, the Multus had a M-code for running mill code, correct? So you should be able to fill in your values and go!
