CNC Lathe Feed processing route refers to the path that the turning tool starts to move from the tool setting point (or the fixed origin of the machine tool) to CNC machining until it returns to the point and ends the processing program, including the path of cutting and the path of non cutting idle stroke such as cutting in and cutting out.
The feed path of finish machining is basically carried out along the contour sequence of the parts. Therefore, the key to determine the feed path is to determine the feed path of rough machining and idle stroke.
In CNC lathe processing, the determination of processing route generally follows the following principles.
① The accuracy and surface roughness of the workpiece to be processed shall be guaranteed.
② It can shorten the processing route, reduce the idle travel time and improve the processing efficiency.
③ Simplify the workload of numerical calculation and simplify the processing program.
④ Some subroutines should be reused.
Advantages and disadvantages CNC machining has the following advantages:
① A large number of tooling is reduced, and complex tooling is not needed to process parts with complex shapes. In order to change the shape and size of parts in CNC machining, we only need to modify the part processing program, which is suitable for the development and modification of new products.
② The machining quality is stable, the machining precision is high, and the repetition precision is high, which can meet the processing requirements of aircraft.
③ In the case of multi variety and small batch production, the production efficiency is higher, the time of production preparation, machine tool adjustment and process inspection can be reduced, and the cutting time is reduced due to the use of the best cutting amount.
④ It can machine complex surface which is difficult to process by conventional method, and even can process some parts which cannot be observed.
The disadvantage of CNC machining is the high cost of machine tools.
