AN EXPERIMENTAL STUDY OF THE CUTTING FORCES IN THE METAL CUTTING PROCESS

摘要

From the invention of turning machine some engineers are trying to increase the turning productivity. The increase of productivity is following after the breakout in instrumental area, such as the hard alloy instrument and resistance to wear cutting surfaces. The potential of cutting speed has a certain limit. New steel types and cutting tool surfaces types allows significantly increase cutting and turning speeds, but with this increase from the recommended by 20% the solidity of the instrument decreases by 50%. For the most operation types the productivity increase begins from the feeding increase. On the average feeding increase by 20%, the self cost decreases by 15% when manufacturing the detail in large numbers.
