Contour Cutting Around the Outside Using Cutter Compensation
In the above example the part is cut and the 4.000” measures 3.980”. Now the part is being cut on two
sides so .01” needs to be added to each side. If the D is in diameters (+.02”) is added to the D Wear.
If the D is in radii (+.01”) is added to the D Wear column for tool #1.
Roughing Applications Using Cutter Compensation
One of advantages of using Cutter Compensation is that different size tools can be used with the same
program. All that needs to be changed is the D value for the respective tools. The only limit is that the
distance of the move to turn on the cutter compensation (G41 or G42 block) be larger than radius of your
tool. Also their maybe limits with respect to interior radii with pocket milling. For example the part
contour program below using tool compensation could be used with a 1/2” end mill or 3/8” end mill.
