Investigation of the processing complex shaped surfaces on the basis of non-linear motion of the forming


For products of modern engineering is characterized by the complexity of the design of parts, the
inclusion in them of free-form surfaces. This is directly reflected in the production of tooling, dies,
molds, casting models and similar products. When processing such parts, large volumes of cutting
layers are removed, associated with obtaining complex spatial forms, resulting in a decrease in the
durability of an expensive tool, hence a decrease in the productivity of the process. Improving the wear
resistance of cutting tools is one of the important tasks of mechanical engineering technology.
To increase the milling efficiency of complex shaped surfaces (СSS), mainly methods are used
to improve the properties of the tool material, change the composition and properties of the surface layer
of the tool, apply thin film coatings, reduce the roughness of the working surfaces and improve the
operating conditions of the tool using the coolant cutting system.
One of the most promising methods for increasing tool life is the use of processing methods in
which tool movements are nonlinearly coordinated so that this leads to a constant displacement of the
tool cutting edge relative to the cutting surface.
