On-line CNC Courses

Basic CNC programming courses (machining center and turning center)

The scope for these two courses is limited to G code level, manual programming. While there are other programming methods (primarily computer aided manufacturing [CAM] system programming), most experts in the field will agree that an understanding of manual programming is of paramount importance to any CNC programmer. Indeed, it is best to first learn about certain CNC features (like program zero, motion types, compensation, among many others) at G code level. Trying to learn the numerous CNC features while also attempting to learn a complex CAM system can be difficult and confusing - in some cases, an insurmountable task.

Prerequisites

We assume students enrolling in these classes currently possess certain basic machining practice skills, including the ability to read and interpret blueprints, the ability to interpret tolerances, the ability to use shop tools and measuring devices, and the ability to perform arithmetic calculations (at least addition and subtraction).
