The path of the chamfering tool is calculated as follows.
C
θ
∆y
∆x
ι
ε
ι : Samll diameter: For chamfering tool
θ : Angle: Tool nose angle of a chamfering tool
ε : 3 mm fixed. Parameter No. 9214 (TEA) can also be used
to compensate the tool–nose position in the tool file. In
this case, however, the tool–nose position compensation
must have already been set in the tool file.
∆x= ι/2 + ε tan (θ/2)
∆y= ε + C ⁄ tan (θ/2)
(Tapering)
When tapering, input the taper angle (A). The range of the taper angle is 0_ – 90_.
Finishing pitch (K) is entered, making it possible to extremely reduce the pitch in Z direction during finishing
for smooth finishing surface. It is possible to select either ”Machining Upper or Lower Surface” for the refer-
ence surface in XY direction according to the symbol of bottom machining allowance (V).
When the bottom surface machining allowance V y 0, the cutting bottom surface (Z) is a reference
surface.
When the bottom surface machining allowance (V) < 0, the cutting upper surface (Z–V) is a reference
surface.
