Increase In Flank Wear Research Articles

切削工具の逃げ面摩耗と切削力の変化

The cutting mechanism under conditions of progressive flank wear was analyzed theoretically. General expressions for depth of cut and stock removal rate were derived, taking variation of tool forces into consideration.Ferritie nodular cast iron was machined with carbide and ceramic cutting tools, and variation of tool forces associated with progress of flank wear was investigated. It was found that tool forces increased with an increase in flank wear in almost linear relationship, and that the rate of increase in feed cutting force was greater than that in principal cutting force.

Temperature Distribution at Tool-Chip and Tool-Work Interface in Metal Cutting

Abstract A noniterative method is presented for the computation of temperature distribution both at the tool-chip and tool-work interface in metal cutting. Temperatures at the tool-work interface increase appreciably with the increase in flank wear. This phenomenon contrasts to the relatively minor influence on tool-chip interface temperature as crater wear develops. Results include a three-dimensional temperature distribution at the tool top surface.
