GCode is Complicated
G-Wizard Makes it Easy

Pocket results seem aggressive

Hi. I’m working on a softjaw for workholding as shown here: http://a360.co/1Sr6WDd

GWizard suggests roughing out the pocket with a 1″ endmill and 12mm stepover. That seems like a lot for the Tormach PCNC1100 I’m using, but it’s a brand-new machine and I don’t know its capabilities yet.

Does this seem right? Here’s a screenshot of GWizard:

Rick, the pocket results are intended to be aggressive–that’s the purpose of CADCAM Wizards.  They will find a solution that is right up against the available limits.  If the Tormach is set up right, it’ll do the work. OTOH, if you want to take it easy when starting out, my recommendation is to derate the spindle horsepower.  Set it to half what the spindle is rated and CADCAM Wizards will give you recommendations within that limit.  That leaves you some margin for error.

When you’re pushing the Tormach to the limit, make sure you tool holder is set up right to avoid pullout.  Tormach has some information on this available.  I would think that’d be your biggest risk.

For others who see this, here’s a link to the Tormach guide to avoiding pullout.
