Abstract

The method of calculating forces, temperatures in the cutting zone when turning grooves in workpieces of various structural materials with grooving cutters, is disclosed. As a general case, the standard groove cutters with soldered plates and the geometry of which corresponds to GOST 18884-73 are considered. The verification strength calculation of the cutting wedge is performed. The geometric parameters and strength characteristics of the tool material are justified. The wear-resistant coating to reduce temperature and increase tool durability was analyzed and selected. The conducted study has shown the ineffectiveness of the standard soldered turning groove cutters use at modern machine-building enterprises in the machining of workpieces of increased hardness structural steel. Design features and conditions for the use of built-up tool, equipped with changeable multifaceted plates (CMP) of the developed shape and size, are justified. The manufacture and subsequent implantation of the developed built-up cutters equipped with CMP of high-strength hard alloy will ensure an increase in the reliability of the tooling system of the machine-building enterprise and eliminate the breakage of the cutting tool and associated equipment downtime. The use of high-temperature wear-resistant coating on CMP will improve the performance of the machining of grooves on the workpieces of increased hardness structural steel and increase tool durability.
