The optimization of polytetrafluoroethylene (PTFE) cutting parameters for minimizing energy consumption in CNC turning of using Taguchi method

PTFE is one of the important materials in the manufacturing of various products. This material is widely used in various fields because of their light weight, corrosion resistance. Materials with good machinability require little energy to cut, less processing time, and tools. Along with the development of machining technology that requires high accuracy and precision, the development of the turning machine has become a modern machine by involving a computer program whose machine is called CNC turning. The cost required to use a CNC lathe is very high, besides that the machine also consumes a high level of energy 99% of the environment. Reducing the energy consumption of a CNC turning process can be done by implementing sustainable manufacturing. This study aims to determine the optimal process parameters for the CNC turning process in minimizing energy consumption. The method used to minimize energy consumption is the Taguchi method. This study resulted in the optimal process parameters for the depth of cut is 2 mm, the spindle speed factor is 1250 rpm, and the feed rate is 0.5 mm/rev.
