The
FlashCut CNC control system is composed of four parts as
follows:
- The
FlashCut CNC Software running under Windows
is the operator control panel. It sends real time motion
commands to the Signal Generator over a high speed serial
link.
- The
Signal Generator uses it's own microprocessor
to generate precision timed step and direction signals
to drive up to four stepper or digital servo drivers with
full 3-D interpolation using "Continuous Contouring."
- The
Motor Drive Box, stepper or servo, provide
the power to directly control up to 4 motors. Servo Drive
Boxes use position feedback from encoders to maintain
a true position.
- The
Motors move the axes on the machine precisely
as commanded by the FlashCut CNC System.

Stepper
vs Servo
Stepper motor control is the most cost-effective way to
control a machine tool. The accuracy is exceptional, and
the price is very reasonable. The only limitation is that
the maximum speeds for rapid moves and cutting moves are
not as high as for servo control.
Servo
control uses feedback from an encoder to constantly monitor
the machine toolıs exact position. Using the feedback signals,
the control system can achieve very high speeds and perfect
accuracy, even under very strenuous conditions.
