Need Help!- Makino Hyper5

[tazbaby]

We are using the Makino Hyper5 for cutting molds and dies, and have recently noticed a BIG problem when cutting with Ballnose cutters !

Ballnose cutters are cutting 0.035mm to deep ! It doesnt matter what the diameter of the cutter is its always 0.035mm to deep, we have checked the programs and all looks fine, we even ran a program for a ballnose using an endmill and it cut perfectly to depth.

Has anyone seen or heard of this problem ? Is it a problem with the Makino itself ? All endmill programs run and cut to tolerance perfectly. Cutters from 6mm to 0.4mm diametre with an R0.1 cut perfectly..

TIA

Well - Makino qustion shouldn't be asked in Industrial Hobbies thread.

It sounds to me like your tool setter probe position is out of whack.
Try manually zeroing your Z offset to verify.

Thankyou for your reply !

My apologise for posting in the wrong section.

If the Z setting probe was "out of whack" would this not cause endmills to over cut by 0.035mm too ?

I believe it has something to do with the probe !! but for it to work with all but one type of cutter is puzzling !!

If your XY position for the probe is out say 1/8" then it will be "riding up' the radius of the ball mill whereas it is still seeing the "flat" of the flatmill.
