OKUMA 4th axis

[Manuel0822]

Just got a new Okuma Mill with 4th axis and we're trying to get the 4th axis going but it looks like this machine needs the M15/M16 on each line were a 4th axis pos is being output. Problem is the post would not compensate for the 4th going from CW to CCW.

Eg. If I program

 

M21 (UNLOCK)

M15

G00 G90 G15 H1 A0. X-1.5 Y.5 S1500 M03

A90.

A-90.

M20 (LOCK)

 

the Machine will go to A90., then to A270. on the same CW direction, unless I enter an M16 before my A-90. It ain't a big deal for indexing but it will suck if we try to engrave a part. Is there a setting on the Mill that we turn off so it will go either way? or we'll we need to get our post mod to do this??

 

If I need to get the post modified, where would I start? using the MpMaster.

most posts have switches that alows you to se desired formt. depends which type you have. that should not be a big problem to set.

You need to talk to Inhouse. The MPMaster Okuma post does what you need. I assume it is the MPMaster Okuma post you are using? Although from memory, I had a bit if trouble with it. (It is has been a while since I used/programmed the rotary axis on our MB56)

 

Check with Okuma as well. I have a feeling you can actually switch off the M15/M16 function, though don't quote me on that.
