Using the function of the fourth axis indexing head, the general polyhedron machining can be completed, such as the machining of four surfaces and four grooves of the turbine air compressor shell. One clamping can complete multiple processes, and its machining accuracy and efficiency can be significantly improved. The following will be explained by the rotary indexing control of the indexing head.
The indexing movement of the numerical control indexing head is generally that the servo motor drives a group of worm gears and worms through the coupling to make the indexing head rotate and index.

Determination of processing 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 advance route of finishing is basically along the outline of its parts. Therefore, the key to determine the feed route is to determine the advance route of rough machining and idle stroke.
In CNC lathe machining, the determination of machining route should generally follow the following principles.
1, which should ensure the accuracy and surface roughness of the machined workpiece.
2. Shorten the processing route, reduce the idle travel time and improve the processing efficiency.
3. Try to simplify the workload and processing procedures of numerical calculation.
4. For some reusable programs, subroutines should be used.
