GM-11 NEW ADVANTAGES IN GEAR GRINDING THROUGH FLEXIBILITY OF PROCESS SELECTION(MANUFACTURING OF GEARS)

概要

論文の詳細を見る
Current trends in gear manufacturing include shorter production lead time and a rising number of gear variants due to a larger variability of product configuration. Both trends create the requirement for a reduction of lot sizes and an increasing frequency of machine change-overs. The latter is additionally intensified by a continued decrease of cycle time through high performance machining processes (Fig. 1). Different gear grinding processes, i.e. discontinuous profile grinding and continuous generating grinding, are well known but have individual strengths and limitations. In the past, gear manufacturers were often limited to the selection of the type of gear grinding process depending on single-function gear grinding machines that were available. Considering the increasing number of different gear variants, technical and economic advantages can be achieved by selecting the optimum gear grinding process depending on the individual workpiece requirements instead. Gear grinding machines offering full flexibility regarding process and tool selection are required. In view of the increasing change-over frequency, methods to reduce set-up time are being emphasized, particularly allowing frequent change-overs between the different types of grinding processes and tools.[figure]
