Geometric analysis and design of circular form tools

Abstract Supposing serial or quantity production of cylindrical workpieces having complex geometry the application of circular form tool is applicable. This type of cutting tool has complex geometry as a consequence the geometric and the manufacturing design take a lot of time and cost but it is economical since the cutting process is quite fast. In addition, the tool usage is feasible on conventional or CNC controlled machines and the process is independent from the workers’ facility. The tool profile is the conjugated pair of the workpiece profile. This tool geometry has high resharpening area that is advantageous comparing other form tools. The goal of this study is the manufacturing analysis and the geometric design of those tools. The geometric design process will be determined detailedly in constructional and mathematical way. After them a concrete tool generation process including CAD design will be shown.
