Hello and thanks in advance for any help.
I am new to CNC turning. I have been getting use to the control on the Haas TL-2 in particular the IPS quick programing layer.
I have been able to setup the tools and the offsets and use the canned operations. I have one problem that is driving me nuts.
When I setup an OD turning cycle (G71), the machine cuts air for several passes , for example:
start diameter: 2.000
Final diameter: 1.75
Depth of cut: .010
The cut always starts about .050 larger than the start diameter. So in the example above the canned cycle would start and progress like this:
X= 1.990 (finally removing stock)
The final diameter turns out fine.
I cannot figure out where the "boy now that was stupid" ah ah answer is. Does it have to do with the retraction clearance maybe?
Why not post the program so we can help. A few blocks before the G71 and a few blocks after the end of the shape definition.
