CNC machining route determined

Published on:2015/12/24 16:33:08   Reading:times



CNC lathe feed processing line refers to turning movement from the start point of the knife (or machine fixed origin), until you return to the point and end machining path through the program, including the cutting tool path and cut, cut out other non-cutting air travel path.
Finishing feed line is basically carried out along its contour parts order, therefore, to determine the feed line focus is on air travel and to determine the roughing feed line.
CNC lathe machining, processing routes to determine the general principles to be followed the following aspects.
① should be able to guarantee the accuracy of the workpiece to be machined and surface roughness.
② the machining shortest route, reduce air travel time, improve processing efficiency.
③ Try to simplify the numerical calculation workload, simplify the machining program.
④ reused for some programs, you should use subroutines.
CNC advantages and disadvantages

CNC machining has the following advantages:
① a significant reduction in the number of tooling, machining parts of complex shape without complex tooling. To change the shape and size of parts, only need to modify the part program, applies to new product development and modifications.
② stable processing quality, high precision, high repeatability, adapt aircraft processing requirements.
③ more variety, small batch production conditions high production efficiency, reduce production preparation, machine adjustment and operation inspection time, and the use of optimal cutting capacity and reduce the cutting time.
④ processed conventional methods are difficult to process complex surface, even working some of the processing site can not be observed.
The disadvantage is that the machine tool CNC machining equipment is expensive, requires maintenance personnel with a high level.
CNC machining

CNC also called computer gongs, CNCCH or CNC machine tools is actually a name for the Hong Kong side, it was brought to the mainland PRD, in fact, CNC milling machine, in Canton, Jiangsu, Zhejiang area was called "CNC machining centers' machining of a species, is a new processing technology, the main job is to prepare the machining program, upcoming original handiwork into computer programming. Of course, the need for manual processing experience.
