Basic classification of CNC system
摘要：The control tool moves the precise coordinate position of the workpiece from one machining point to another, but does not control the track of the movement between the points, and does not make any machining during the movement. The equipment of this kind of system includes NC drilling machine, NC coordinate boring machine and NC punching machine, etc. .
(1)Point-to-point control CNC system
The control tool moves the precise coordinate position of the workpiece from one machining point to another, but does not control the track of the movement between the points, and does not make any machining during the movement. The equipment of this kind of system includes NC drilling machine, NC coordinate boring machine and NC punching machine, etc. .
(2)Linear control CNC system
Not only the precise position of the control point and the point, but also the tool path between the two points is a straight line, and the tool can be processed at a given feed speed during the movement, its auxiliary function requirements are also more than the point control CNC system, such as it may be required to have spindle rotation control, feed speed control and automatic tool exchange functions. This kind of control mode mainly has the simple numerical control lathe, the numerical control boring and milling machine and so on.
(3)Contour control CNC system
This kind of system can control two or more coordinate directions strictly, that is, not only the travel position of each coordinate, but also the velocity of each coordinate. The motion of each coordinate coordinates cooperate with each other in accordance with the prescribed proportion, coordinate precisely and continuously to form the required straight line, oblique line or curve, curved surface. The equipment which adopts this kind of control mode includes numerical control lathe, milling machine, machining center, Electric Machining Machine Tool and special machining machine tool, etc. .
