Modified Taylor's Tool Life Equation and Effects of Feed on Tool Life.
The modified Taylor's Tool Life equation is given as:
VTnfadb=C
Tool Life varies with feed rate. At a low feed rate, the area of the chip that passes across the tool surfaces will be relatively large for a given volume cut, and relatively small for a high feed rate. From this, it seems that tool life should increase with the increase in feed rate, but as the cutting forces on tools also increase with the increase in feed rate, it leads to decreased tool life. Thus these two opposing influences of the feed rate upon tool give rise to an optimum rate of feed which is about 0.25 to 0.50 mm/rev.
How to Calculate Feed given Taylor's Tool Life, Cutting Velocity, and Intercept?
Feed given Taylor's Tool Life, Cutting Velocity, and Intercept calculator uses Feed Rate = (Taylor's Constant/(Cutting Velocity*(Depth of Cut^Taylor's Exponent for Depth of Cut)*(Tool Life in Taylors Theory^Taylor Tool Life Exponent)))^(1/Taylor's Exponent for Feed Rate in Taylors Theory) to calculate the Feed Rate, The Feed given Taylor's Tool Life, Cutting Velocity, and Intercept is a method to determine the maximum Feed that can be applied on the Workpiece to get a specified Tool Life under a given Cutting Velocity. Feed Rate is denoted by f symbol.
