Testing and Implementing the Process of Groove Cutting on the Part «Insert» Using Vortex Method

The article presents the results of work on the development and introduction of a new vortex method of machining profiled seal circular grooves on conical and cylindrical lateral rotational surfaces. Tooling was designed and manufactured to implement this method. A method of adjusting the technological system was developed. The jig boring machine 2E440A and the CNC vertical milling machine GF217TS5 were upgraded, and grooves on more than 5680 and 1600 parts were machined, respectively. Experiments on three sizes of grooves were carried out. The grooves were cut on lateral rotational surfaces of the part «Insert SK 003» at Sardarov Machine Building Plant, and on the parts «Insert 4KM 002» and «Insert 3RK 004» at Sabunchinskiy Research and Manufacturing Association. Three types of respective tools were also tested. The author investigated the accuracy of the cut grooves, their position on lateral rotational surfaces and the surface roughness. It was established that the grooves on all the parts met drawing specifications. The application of the vortex method for groove cutting instead of contour machining by end mills allowed reducing the machining time more than 8-fold. The replacement of the single-tool vortex cutting by the double-tool cutting reduces machining time more than 1.5 times.
