G5 on Mazak 414 M32B

[BKBridges]

Hey,
Just installed a used Mazak 414 with Mitsu M32B. Is anyone familiar with the G5 high speed machining mode on this machine? Im used to G3 on the old Fanucs. Would like to go 70+IPM, do I need the G5?
Thank You,

No, you should be able to feed at 70ipm without any high speed software. For better accuracy, you can use G61.1 but that's also a software option for that control.

Psychomill, Thanks!
We noticed some G61.1 in the previous owners code (blessed with at least one option I guess!)
We noticed a wierd thing with the display. We test ran a program and the display showed the tool crashing the workpiece after the tool change.
code:
G91G30Y0Z0
T1T2M6
G0G80G90G40S1000M3
G54Y1.Z1.M8
etcetc
we added Z6. to the G54 line, and the crash on the ISO display went away. we ran the program and the Z axis craashed positive... Reset the alarm, removed the Z6. and the program runs great... wierd?
So far the only other learining issue weve hit is with G41 g42 cutter comps. Where are the comps specified? Do we need to make a new tool for each D?
We like the Mazak a lot and want to understand its differences (from our fanuc based stuff)

What do you mean Z crashed positive? Whether or not the Z crashes will depend on how you're setting your tool offsets (assuming positive), how/where the work offset zero is and the relationship of the two.

As for cutter comps... this depends on how the machine is set up parameter wise. You can run a few tests but if you have the machine's "old programs", this may give you a clue if you scan and find a G41 call line.
Back in the days of the "32" controls, most places used the Tool Offset page to control length and diameter comps unless they were using Mazatrol programs. The Tool Data page generally consisted of generic tools set up with useless data so that the magazine would run. On these controls, extended tool offsetting (WEAR comps) was an option so you may have to use higher value offsets to control cutter comps (for example.... D41 to control T1, etc).
It's possible that Tool Data is controlling the comps as well though if the parameters are set that way. In that case, the comps would be updated on the Data page of that tool.

You can run a few FANUC type comp programs to test this out...

Psychomill,
Im a fool. Found the tool offset lists right next to the work offset lists...adjusted a few drill cycle parameters and changed the start params and we're making chips with great results. Now we can look at some of the cool torque controls to speed things up. Its already cutting much better on this part than the MV junior or V4 could. The 1.5" drill never sounded so good. The display thing is still strange, but it looks like a parameter driven thing as well. We'll look into that after the first op is done next week...Your Mazak skills are much appreciated!

.... yeah but now, you're a smarter "fool"...

All fun and games.... Good Luck!

The display has some parameter sets for but not much on a 32 control. Basically just have to get used to the dashboard like you would in a new car.....
