Creo 5.0 HSM Rough

[shaun1]

Having issues with HSM Rough, Parameters are set up for Rough Only, Constant Load, Step Over .03 , Max Step Depth .625   

Issue with this is it still wants to do a full retract when the tool path starts to work in corners. Instead of doing a small tool lift.

Any suggestions or solution's would be appreciated.

Also set

MIN_RETRACT_DISTANCE 8

8 inch  or some other large number

That seemed to solve my issue, Thank you!

I am using 5020 and cannot find this option in my parameters.

Where is it ?

I did have the same issue that you are having. No luck with the HSM Rough. I reverted back to using a Roughing tool path or a Volume Rough tool path using a constant load, Min_Retract_Distance will be in there and so far have had good success with this.
