abstract = {A system and procedures are developed to optimize the cutting speed for CNC turning. The current amount of tool wear is estimated based on the in-process cutting force measurement by applying the method developed and reported previously. Once the tool wear is estimated for the different cutting speeds, the coefficients of the Taylor's tool life equation are determined or successively modified based on the estimated tool wear data. The optimum cutting speed is obtained by referring to the criteria of either the minimum production cost or the maximum production rate. The system developed is applied to actual turning of carbon steel with coated carbide tools, and it has been proved that the system runs satisfactory. The method developed here can be readily applied to unknown combinations of the work material and die tool, as it searches the optimum cutting conditions automatically while the process is going on.

abstract = {The aim of this research is to develop an in-process tool wear monitoring system for CNC turning machine. The exponential decay function is employed to represent the relation between the nominal specific cutting resistance and feed rate. An index value α in the exponential decay function is defined to estimate the flank wear, which is equivalent to the rate of increase in the nominal specific cutting resistance at zero feed rate as compared to that at infinite feed rate. In order to obtain the characteristic value α, the additional cutting cycles is proposed here to alter the feed rate deliberately during the normal cutting cycle to measure the cutting forces and identify the rate of increase in the nominal specific cutting resistance at smaller feed rates. Series of cutting tests were carried out to estimate the flank wear, and it is proved that the index mentioned above can be a good measure of tool wear, even though the depths of cut, the cutting speeds and the cutting tools, as well as the work materials are different.},
