So your Machining center can program the Z axis in Inches / Spindle Rev?
Can you program a X axis to do the same?... say... 0.500 / spindle rev ?
If so, when did that start?... when Rigid tapping was introduced??
I'm guessing that the reduced spindle speed for this tapping operation is helping you more than what ever else you did.
Gotta love it when people don't listen to good advice.
It't not that simple. Machine has scales. I do not have the procedure for testing backlash with scales, and to my knowledge you can't just turn them off.... I do have the documentation for turning off scales, and it is much more than a ten minute job, and involves re-establishing the axis home positions. Not exactly fun in the Z...
I don't know. At this point i am just more frustrated than anything. I like things to be working right, and have been pushing for us to stay on top of things, but I can only do so much and have so so so much on my plate. Last thing I need is to have to spend my day at the machine doing diagnostics, but if that is what I end up doing, than that is what I end up doing. All this does is push the dates out further for the next parts that need to be done on the machine, and push me deeper and deeper into the hole that is in the middle of the pile of work I have sitting around my desk in my office.
This tells me there is slop in the system. The issue here is the scales shouldn't let this happen from what I understand.
I never thought about trying it with the machine off, granted it wouldn't be as accurate due to potential minute screw back feeding, but it would definitely give us an idea of what we are looking at.
between two parts that we had the most trouble with. In fact these parts have the most risk potential from a material and heat treat standpoint, as we are tapping on the border of a friction stir weld.
