How can I get feeds and speeds for Macor and other exotic materials in G-Wizard Calculator?


If the material is just an alloy of an existing category, a new steel or aluminum for example, I can typically add that fairly quickly to G-Wizard and will do so on request from customers.

For more exotic materials, it can still be done, but is a bit more work.  

Macor is interesting stuff.  As a machinable ceramic, I’m sure it corresponds well to any existing material family.  I would just dial up something generic and hard code the Corning Machining Guide figures.  I found that guide by Googling for:

Something similar will usually get you what you need, which is figures similar to that guide.  Once you have them, just dial up something generic like Mild Steel, and use the surface speeds and chiploads in the Mfg’s inputs which are described here:
