Embodiment Construction
[0056] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0057]Step 1: Define the geometric parameters of the end edge clearance.
[0058] like figure 1 As shown in Fig. 1, the grinding plane is first selected as a certain plane passing through the axis of the rotating body of the tool, and the angle between it and the cutting edge is specified by the user to achieve the best grinding effect. In order to make the contour between two adjacent edges of the ball-end cutter close to the spherical contour, the present invention defines the outer contour of the end edge gap as a section of arc on the grinding plane. Let the starting point of the arc be P 0 , the end point is P 1 , the arc center is O b .
[0059] (1) Starting position. Arc starting point P 0 The location of is constrained by the starting radius R and the starting length L. where the starting point radius R is defined as p...
