Forecasting residual and operating stress in soldering cutting tools with tungsten-free hard alloy inserts

摘要

The results indicate a reduction of defects in soldering turning tools through optimal dimensions of a solder. In this paper stress in a flat insert is calculated and the results of laboratory tests of cutters iron-carbon soldered are presented. The optimal dimensions of the solder are selected according to calculations conducted. The ability of a tool to perform its functions depends significantly on real defects developing in the process of toolmaking [1]. Among the most hazardous defects there are pores, impurities, structural inhomogeneity, inequigranular structure, micro- and micro-cracks. The investigation is aimed at forecasting residual and operational stress in iron-carbon soldered cutters.
