A possibility for machinery billet machining effectiveness increase at the expense of the use of high-speed grinding machines operated in an automated cycle of machining mode changes is considered. It allows performing operations of roughing and then finishing ensuring the required accuracy and quality of surfaces worked. The application of high-speed force grinding allows rejecting rough and finish preliminary milling and, in such a way, decreasing the number of machine equipment, hard-alloy cutters, production areas and increasing labor productivity.

There is considered a possibility of effectiveness increase of machinery billet flat deep grinding at the expense of high-speed machining use and also grinding on an automatic cycle of grinding mode changes. The application of high-speed deep grinding, for instance, slots or profiles of turbine blade locks allows rejecting their preliminary milling, carrying out single position machining on one machine which increases machining accuracy and its capacity.

On the basis of experiment results there is carried out an analysis of the cutting parameter impact upon force components of cutting at processing composites with cutting edges under different cutting conditions. The analysis of circular graphs of force components of cutting reasoning from the specified role of each force in the course of cutting is carried out.

he results of experimental work on abrasive-belt creep feed grinding of 20X13 steel and VT3-1 alloy are presented. The advantage of abrasive-belt creep-feed grinding, which allows significant increasing of the efficiency of work on a workpiece of machine parts, particularly having cam surfaces, such as steam and gas turbine blades, propeller blades, etc., is shown.

Investigation results on the impact of processing time and a cutting way upon wear a cutter made of different tool materials at the machining of polymeric composite blanks are shown. There are given recommendations on cutter plate geometry of a tool and the most efficient tool materials.
