Cutter comp problem

[tlarue]

When I use cutter comp in control I am having a problem with the program creating arcs in corners that are smaller than my tool. I keep getting CRC error. Can anyone help me with this.

Yup,

 

either a smaller cutter, bigger radius or regular cutter comp.

 

This is one of the pitfalls to control comp.

use optimise, that will remove the arcs in corners.

Where do I find optimize

Control Comp SUCKS!!! Wear Comp RULES!!!

wear is the way to go.

IMNSHO wear comp is for people too lazy to set their machines up correctly

You wont find optimize if you are using lathe. I have complained about this before...I use control comp all the time (because we can't maintain stock on inserts).

Bruce, are you burning the candle at both ends over there?

 

I remember an earlier post of yours talking about the problems your machines have with running toolpath (wear) instead of partpath (control).

 

I'm wondering if it depends on the machine controls.

 

When I started in this business (1981) the shop I worked at used partpath programming because it was easier to write programs by hand. The problem we had was that it took a lot more room to engage the toolcomp. If you were in a tight space or didn't give it enough room you would either get an alarm or an undercut in the part. We were using Fanuc and Fadal style controls.

 

When we switched over to toolpath programming this problem was eliminated.

I see there is a definite opinion for control comp or wear comp. But...

 

How is wear comp better?

 

I have always been a control comp guy, buy am willing to change if there is an advantage to wear comp.

There was a thread arguing the points of this not long ago... here.

Thanks for that thread. I will stick with control comp.

We have a mix of iso and hiedi machines. My personal opinion is that a tool table should contain all the relevent data that it is supposed to. Especially on a control such as a heidi TNC where there are a lot of conversational options for the operator to use.

 

As far as the leadin issue goes the math works out the same either way, your input in the leadin page just needs to be valid. On control comp if you use a perpindicular entry as long as the amount is greater than 50% you are good to go. We did use wear for a while, but like I said, wrong mix of controllers to make it happen.
