I am new to CNC and I have recently just switched from using SputCAM 8 to SolidCAM. In SolidCAM there is an entry for "Z Feed" that I have not heard of or come across until I started using SolidCAM.

I use GWizard to calculate my feeds and speeds. My question is, should I use the same feed rate for Z that I use for XY when simple milling? What about when I am cutting pockets with helical moves? Use the interpolation calculator for this in GWizard and put that value into Z?

Any advice on this subject will be greatly appreciated.
