What principles should be followed for CNC machining of moulds?

2021/09/25



Before carrying out CNC machining of molds, we must understand and master some basic principles that should be followed for CNC machining of molds. Because only when we follow these principles can we make the mold CNC processing more professional, reasonable, safe and effective. It is also able to improve the quality of processed products.
 
Mold CNC machining should follow which principles
 
① should be able to ensure the accuracy and surface roughness of the machined workpiece.
 
②Make the shortest machining route, reduce the empty travel time and improve the machining efficiency.
 
③Simplify the workload of numerical calculation and simplify the machining procedure as much as possible.
 
④For some reused programs, subroutines should be used.
 
CNC advantages and disadvantages CNC CNC machining has the following advantages.
 
①Massively reduce the number of tooling, processing the shape of complex parts do not need complex tooling. If you want to change the shape and size of the parts, you only need to modify the parts processing program, suitable for new product development and reshaping.
 
②Stable machining quality, high machining accuracy, high repeatability, adapt to the processing requirements of the aircraft.
 
③Multi-species, small batch production under high productivity, can reduce production preparation, machine tool adjustment and process inspection time, and due to the use of the best cutting volume and reduce the cutting time.
 
④It can process the complex type surface which is difficult to process by conventional method, and even process some unobservable processing parts.
 
CNC lathe feed processing route refers to the turning tool from the point of tooling (or machine tool fixed origin) to start the movement, until the return to the point and end the processing program after the path, including the path of cutting processing and tool cutting, cutting out and other non-cutting empty stroke path.
