What is CNC computer machining used for?

CNC, also known as Computer Palace, CNCCH or CNC machine tools, is actually a name of Hong Kong. Later, it was introduced to the Pearl River Delta in Chinese mainland, which is actually a CNC milling machine. In Guangzhou, Jiangsu, Zhejiang and Shanghai, some people call it "CNC machining center". General CNC machining refers to precision machining, CNC lathe, CNC milling machine, CNC boring and milling machine, etc. Determination of NC machining route

NC lathe feed machining path refers to the path that the lathe tool passes through the tool alignment point (or the fixed origin of the machine tool) until it returns to this point and ends the machining program, including cutting machining path and non-cutting idle travel path such as tool cutting and cutting. The feed route of finishing is basically along the outline of its parts in turn. Therefore, the key to determine the feed route is to determine the feed route of rough machining and idle stroke.

In CNC lathe machining, the determination of machining route should generally follow the following principles.

(1) shall ensure the accuracy and surface roughness of the machined workpiece.

② Shorten machining route, reduce idle travel time and improve machining efficiency.

(3) Try to simplify the workload of numerical calculation and simplify the processing procedures.

(4) For some repetitive programs, use subroutines.

NC machining has the following advantages:

(1) The number of tooling is greatly reduced, and complicated tooling is not needed to process parts with complicated shapes. If you want to change the shape and size of parts, you only need to modify the processing program of parts, which is suitable for new product development and modification.

(2) The machining quality is stable, the machining accuracy is high, and the repeatability is high, which meets the machining requirements of aircraft.

(3) In the case of multi-variety and small batch production, the production efficiency is higher, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time because of the use of the best cutting parameters.

④ It can process complex surfaces that are difficult to be processed by conventional methods, and even some unobservable machined parts.

The disadvantage of NC machining is that machine tools and equipment are expensive and require high level of maintenance personnel.
