Cutting-Tool Materials and Cutting Fluids
The reasons for the availability of a large variety of cutting-tool materials is best appreciated by reviewing the top eight parameters in the first column in Table 22.2 on p. 638. Among various factors, the type of workpiece material machined, the type of operation, and the surface finish and dimensional accuracy required all affect the choice of a cutting-tool material. For example, for inter...
متن کاملThe Impact of Cutting Tool Materials on Cutting Force
A judicious choice of insert material, tool geometry and cutting conditions can make hard turning produce better surfaces than grinding. In the present study, an attempt has been made to investigate the effect of cutting tool materials on cutting forces (feed force, thrust force and cutting force) in finish hard turning of AISI D2 cold work tool steel. In conclusion of the results obtained with...
متن کاملThe Effects of ZrO2 or Tic on the Performance of the Alumina-Based Ceramic Cutting Tools
Two types of alumina-based cutting tools with compositions of 90 vol.% Al2O3+10 vol.% ZrO2 and 80 vol.% A12O3+20 vol.% TiC are produced by isostatic pressing and sintering technique. The effects of these additives on the mechanical properties and cutting performance of these materials are investigated. The tool life in both materials is examined under identical conditions on cutting a grey cast...
متن کاملDevelopment and Application of New Cutting Tool Materials
The development of new cutting tool materials during the last few years is based mainly on submicron hardmetal substrates as well as on new PVD and CVD coatings. The development of submicron and nanopowders with higher strength and higher fracture toughness solves problems in machining high-temp alloys, hard materials, and in dry cutting. Based on physical models used to calculate stress in the...
متن کاملResearch on Cutting Performance of Ceramic Cutting Tools in Milling High Density Fiberboard
The effect of cutting parameters and tool parameters on cutting forces and tool wear were investigated in high density fiberboard (HDF) peripheral up-milling using toughened ceramic cutting tools. The results showed that whether at low speed cutting or high speed cutting, the tangential forces Ft and normal forces Fr increased slowly with the increase of cutting length. The tangential forces Ft...
