I have worked for CNC Software the creator of Mastercam over 20 years. My role was instrumental in the creation of Mastercam University the online training resource. At the time, all examples in Mastercam U were designed around customer support or training issues. Instructors from around the country requested work holding and fixturing to be covered in all the example files in Mastercam U. I am open to doing contract programming, teaching, and helping with your training program.
