Determining Machining Speeds from the Physical Properties of Metals 640044
This paper develops an equation for calculating the machining speed for a specified tool-life by the use of three constants: a tool life-tool shape constant; a work material constant; and a size of cut constant. Representative values for these constants are tabulated, and curves showing the analytical relationship between v60 and feed as well as v60 and depth of cut are included. Experimental tests were conducted to verify the relationships, and the data are plotted on the calculated curves. The correlation between the calculated values of cutting speed with the experimental obtained values is good.
