The machining of metal dies involves a variety of processes that include grinding, polishing andelectrical discharge machining in addition to various cutting processes such as turning, boring, and milling.The precise machining of complex dies, particularly in deep machining, has largely been done byelectrical discharge machining in the past, because the use of end mills and other cutting tools for suchwork has been difficult. In recent years, however, problems such as low machining efficiency and thecreation of an affected layer have made the use of end mill cutting tools the general approach to this task.In the research reported here, our objective was to establish guidelines for the optimum design of smallradius ball end mills for the deep machining of dies by systematic investigation of the cutting toolcharacteristics, which is to say the rotational behavior, cutting resistance, actual rate of depth of cut andmachining accuracy of small radius ball end mills.Here, the guidelines obtained for ultra-deep, highly-accurate machining that is applicable to machiningprograms and is based on quantitative results for amounts of tool wear and tool deflection thatobtained using the optimum tool shape reported earlier are presented
