Sounds like you're learning.
What ever you use, first make certain any long hair is tied back, no baggy clothing and safety glasses. Never machine alone.

Mastercam has been around since the early 1980s. Started in Conn. USA.

Having the SolidWorks - Mastercam experience is a good one.

Mastercam has a lot of teaching materials and a certification. I would check with them but a machining handbook is good for any team for mfg.

Before you machine, run your part through DFM Xpress inside of SolidWorks. You will get a series of messages if holes are too close to edges or too deep or tools just can't machine that square hole.

You can design features in SolidWorks that cannot be machined or too expensive or will add too much stress. DFM Xpress helps answer questions before manufacturing.

Try to review with a mentor if you can. Marie
