(1) Operation
(a) When automatic corner override is not to be applied :
When the tool moves in the order of (1)
→
(2)
→
(3) in Fig. 1, the machining allowance at
(3) increases by an amount equivalent to the area of shaded section S and so the tool load
increases.
(b) When automatic corner override is to be applied :
When the inside corner angle
θ
in Fig. 1 is less than the angle set in the parameter, the
override set into the parameter is automatically applied in the deceleration range Ci.
