Polytetrafluoroethylene (PTFE) is commonly employed in the fabrication Three Wheel Mobility Scooters of fluidic components within the circulatory systems of electronics, biomedicine and other industries.The process of groove cutting plays a pivotal role in the production of intricate PTFE elements.However, achieving the desired dimensional accuracy during the grooving of PTFE workpieces is challenging.This study employed PCD arc cutters to perform cutting experiments on PTFE workpieces with a specific focus on analyzing the cutting temperature, cutting force, groove width accuracy, and uniformity of groove width.
The findings indicate that the cutting temperature is primarily influenced by the spindle speed during the cutting process, with the highest temperature observed at a spindle speed of 1000r/min.Furthermore, the cutting force is predominantly affected by the feed rate, and the largest force recorded at a feed rate of 0.25mm/r.The feed speed has a great influence on CFL CC the accuracy and uniformity of the groove width, and an excessive feed speed has an adverse effect on the cutting accuracy.
Additionally, the grooves exhibit elastic recovery post-machining, leading to a measured groove width smaller than the desired width.In this experiment, the optimal groove outcome was attained with a feed rate of 0.1mm/r and a spindle speed of 200r/min.Consequently, the process parameters investigated in this study can be effectively used in practical production settings to enhance the cutting accuracy of PTFE components.
