DEFINITION OF THE GEOMETRIC PARAMETERS OF THE UNDEFORMED CHIP AT THE CUT-IN STAGE WHEN MACHINING AN EXTERNAL GEAR USING THE POWER SKIVING METHOD

In this study, the process of tool plunging into the workpiece during external tooth cutting will be modelled. Cut-in is one of the most dangerous stages not only in gear turning, but also in any cutting process. The gear cutting process is analytically studied in terms of maximum chip thickness and, on this basis, recommendations for process design are offered. The developed simulation is able to calculate the appropriate cutting geometry for each revolution of the tool cut-in to the workpiece.
