Calculation of the Cutting Forces When Processing Plastic Materials with a Wide Range of Thicknesses of the Cutting Layer

Chip formation patterns, contact interactions on the tools surfaces and cutting force calculations constitute the theoretical foundation of the cutting process. It is important to develop models for calculating cutting forces as this eliminates labour-intensive experimental studies and makes it possible to evaluate accuracy and quality indicators of the cutting process. Considering that for various cutting tools the values of feed and cutting layer thickness range from hundredth to tenth of a millimetre, a research problem of performing a theoretical analysis of the cutting forces in this range is formulated and solved. A method of calculating chip formation parameters and cutting forces when processing plastic materials is proposed. Computing sequencing is organized in the developed user program. The method can be used for conducting research and performing engineering calculations in the subject area of mechanical processing by cutting for various types of cutting tools.
