1)control medium
Control medium is the carrier of storage numerical machining prototype model information, it
can be perforated tape, tape and disk, etc. CNC numerical control processing information
including part process, position of tool to the workpiece and all motion control instruction when
machining parts,they are recorded in accordance with the relevant provisions of the format and
code in the information carrier, namely control medium.
2)numerical control device
Numerical control device is the core of the numerical control machine tools, modern numerical
control machine all use the computer CNC device .The numerical control device generally
consists of input, information processing and output three parts. Control medium through input
unit (such as punch tape reading machine, tape machine, disc machine, etc.) to input,convert to
the information that can be recognized.Through information processing units to process the
received information in accordance with the provisions of the program (such as the interpolation
calculation, the cutting tool compensation, etc.), the prototype model through the output unit issued
a position or speed directive to the servo system, so as to realize all kinds of control functions.
3)Servo system
Servo system is to put all kinds of instructions from the numerical control devices, prototype model
converted into machine tool drive actuator movement parts. It includes the spindle drive unit, feed
drive unit, spindle motor and feed motor, etc.
