AN IMPROVED PROCESS ON CNC LATHE WITH NEWLY DEVELOPED TOOLS TO REDUCE THE PROCESS TIME FOR ROUGH AND FINISH MACHINING OF SIDE GROOVES IN T-GROOVES IN SHAFT OF STEAM TURBINE

摘要

An improved process on CNC lathe to reduce the process time for rough and finishing operation of balancing weight grooves comprises of developing new crank grooving tools with improved grade and cutting geometry. An improved cutting parameters for the developed tool is selected and on the basis of this tool a new CNC program is adapted so that an optimum number of plunge cuts per groove for rough and finish machining of balancing weight groove to reduce the process time.
