| Another benefit of the key
concepts approach is that it allows us to explain things at a broad level
This helps students get the big picture. With so many different CNC
machine and control manufacturers, it's impossible to relate every detail
of how each is handled. For this reason, students must have the ability to
adapt what they learn to their own machine tools once they complete the
course.
In each key concept, we first show the
broad and general reasoning behind how CNC functions, showing students why
they must do things as importantly as how to do them. The same reasoning
can be applied to any form of CNC machine tool. Indeed, the same key
concepts apply to both machining centers and turning centers!
Once they understand this reasoning, we
show them specific techniques needed to apply each key concept to the most
popular control in the industry. All specific examples given are for the
Fanuc control. We chose Fanuc as our example control since it is so
popular, and since many control manufacturers claim that their controls
are Fanuc- compatible (Mitsubishi-Meldas, Mazatrol, Yasnac, Haas,
Fadal, and others).
