Example of formula: chamfer of φ 30 diameter outer end 1.5x60 program: GoX32Z2.

1, and the chamfer starting point diameter x = φ-2xatanθ x = 30-2x1.5x1.732 = 24.804g1x24.804z0f0.2.

2. The starting length of chamfering is Z=0, in which tan60 is g1x30z-1.5f0.15.

3. The chamfer closing point diameter x = φ; G 1Z-50

4. The length of the chamfer closing point z =-a .... . . . .
