How to determine the feeding route of CNC machining?

CNC machining feed path refers to the path that the turning tool returns from the tool setting point (or the fixed origin of the machine tool) to this point and completes the machining program, including cutting paths such as cut-in and cut-out tools and non-cutting voids travel path. The feed lines for finishing are basically in the order of the contour of the part. Therefore, the key to the determination of the feed route lies in the determination of rough machining and idle travel.

CNC machining is the process of machining with CNC machining tools. NC refers to CNC machine tools programmed and controlled in NC machining language, usually g-code. CNC machining The g-code language tells the CNC machine the Cartesian position coordinates used to machine the tool, and controls the tool feed and spindle speed, as well as tool changers, coolants, and other functions. The CNC machining feed route must be able to ensure the machining accuracy and surface roughness of the workpiece. The feed route of CNC machining should be shortened as much as possible to reduce idle time and improve machining efficiency. The CNC machining feeding route should simplify the numerical calculation workload and processing technology as much as possible. Subroutines are used in some reusable programs.

CNC machining has incomparable advantages over manual machining. For example, CNC machining produces parts that are very precise and repeatable. CNC machining can produce parts with complex shapes that cannot be machined by hand. CNC machining technology has been widely promoted. Most factories have the processing capacity of CNC machine tools. CNC milling, CNC lathes, and CNC wire EDM (EDM wire cutting) are the CNC machining methods commonly used in typical job shops.

CNC machining can greatly reduce the number of tooling, so that complex shape parts can be processed without complex tooling. To change the shape and size of the part, it is only necessary to modify the machining program of the part, which can be developed and modified. The CNC machining quality is stable, the machining accuracy is high, and the repeatability is good, which can meet the requirements of aircraft machining. CNC machining has high production efficiency under the production conditions of multiple varieties and small batches, which can reduce the time required for production preparation, machine tool adjustment and process inspection, and can shorten the processing time due to the use of the optimal cutting amount. CNC machining is capable of machining complex contours that are difficult to machine with traditional methods, and even machining parts that cannot be seen.
