Breaking out of the stone age

[Bruce Caulley]

I can also vouch for the technigrip. I actually designed and had made some different shaped steel bodies to fit on a pillar in our 5-axis machines using the techni-grip clamps. We never lost a part, but did smash up a few tools. The vice only let go once and that was on a part that was only just wider than one of the clamps. We had to crash it to do it as well.

BTW, don't overtighten them. Let the dowels and the dovetail do their job.

"With dynamic comp the distance from machine home to centre of rotation is stored in the parameters allowing you to have the origin anywhere you want it. On a machine with this feature there is no real need to programme from centre of rotation."

 

On large Horizontals, where part accuracy is a must (camshafts, in-line bores, etc.), we always had to warm up the machine to get accuracy within .001 tir. This was in a air conditioned shop with both new and older Mazaks. This usually involved tweaking the X axis wpc a few tenths at a time through out the day. I don't know if changing the dynamic comp in the parameters several times a day would be any quicker, maybe even more of a hassle. Heh, I've seen more than a few Operators that couldn't comprehend how to adjust for CL of rot locations and just kept getting further away from it on each succession of parts. Mayby dynamic is the way to go, locking out the parameters so the noobs don't screw up too badly.

You can still have multiple offsets with dynamic comp, if you really want. All it really does is allows the machine to know where the part is relative to centre of rotation by only setting one offset instead of one for each face.

 

A good example would be a box held in a vice where you are going to machine 3 sides. Without dynamic comp you need to set say G54 on the front and take a cut to reference the other sides. Then rotate 90 and edgefind a corner for G55. Rotate to -90 and do the same for G56. (If you vice is in a known location this process can be shortened.)

 

If you have dynamic all you do is set one offset say G54.1 on the first face. As long as you have the toolplanes in MC and the post setup correctly this is all that you need to do. Best thing is you can set this part at any position on the tombstone and the machine knows where the part is in space and compensates accordingly.

As long as the calibration is maintained there should be no real need to move things around unless the temp of the machine keeps moving dramatically.

googled Technigrips no results, does anyone have a link?
