The tool is supposed to one point in programming but the actual cutting blade is not one ideal
point owing to machining technology. Because the cutting blade is not one point but one circular,
machining error is caused which can be deleted by tool nose circular radius compensation. In actual
machining, suppose that there are different position relationship between tool nose point and tool
nose circular center point, and so it must create correct its direction of imaginary tool nose.
From tool nose center to imaginary tool nose, set imaginary tool nose numbers according to tool
direction in cutting. Suppose there are 10 kinds of tool nose setting and 9 directions for position
relationship. The tool nose directions are different in different coordinate system (rear tool post
coordinate system and front tool post coordinate system) even if they are the same tool nose
direction numbers as the following figures. In figures, it represents relationships between tool nose
and starting point, and end point of arrowhead is the imaginary tool nose; T1
