CNC Machining The Principle Of The Route
CNC is also called computer gongs, CNCCH or CNC machine tools is actually a name in Hong Kong, then came to the mainland Pearl River Delta, in fact, is the CNC milling machine, in the wide, Jiangsu, Zhejiang and some people called "CNC machining center"
General CNC machining usually refers to precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc.
CNC machining Processing
Determination of CNC machining routes
CNC lathe feed processing means that the turning tool from the knife point (or machine fixed origin) began to move until the return to the point and the end of the process through the path, including the cutting path and cutting tools, cutting and other non-cutting Empty path.
CNC machining The feed route for finishing is basically carried out along the contours of its parts, so the focus of the feed path is to determine the feed route for roughing and empty travel.
In the processing of CNC lathes, the processing route to determine the general to follow the following principles.
① should be able to ensure the accuracy of the workpiece and surface roughness.
② the shortest processing route, reduce the empty travel time, improve processing efficiency.
③ as far as possible to simplify the calculation of the workload, simplify the processing procedures.
④ For some reusable procedures, subroutines should be used.
CNC machining Advantages and Disadvantages of CNC
CNC machining has the following advantages:
① greatly reduce the number of tooling, processing complex shape of the parts do not need complex tooling. If you want to change the shape and size of parts, only need to modify the parts processing procedures for new product development and modification.
② processing quality and stability, high precision, repeat the high precision, to meet the processing requirements of the aircraft.
③ more varieties, small batch production under the conditions of higher production efficiency, can reduce the preparation of production, machine adjustment and process inspection time, and because the use of the best cutting and reduce the cutting time.
④ can be processed conventional methods difficult to process the complex surface, and even processing some of the processing can not be observed parts.
The drawback of CNC machining is that machine equipment is expensive and requires a high level of maintenance personnel.
