Cycle Time Reduction Studies in Threading

Cycle time reduction is one of the critical aspects for achieving successful production of products. Prompt delivery, high quality of products have now become the significant factors for customer satisfaction. The various methods of programming in CNC systems ensure machine ability, but at the same time optimization and increase in productivity are to be enhanced. Various programming methods in manufacturing of threads were studied in this research work. The cycle times of three different work piece materials during the G76 threading cycle were noted. Then, we proposed G92 cycle of threading to reduce the cycle time. The new process enabled variable depth of cut, less number of passes resulting in cycle time and it is easy to use. The work was practically implemented on a CNC lathe machine and the data related to the experiments were recorded. This method was applied to 10 other work pieces, wherein it was noted that for all types of threads manufactured, a considerable amount of time is being saved and the productivity was increased marginally.
