Output pulse (Hp) distribution by the manual pulse generator to the
X--axis, Y--axis, and Z--axis for the four types is expressed below.
(1)A--C axis type
Xp = Hp × sin (a) × sin (c)
Yp = −Hp × sin (a) × cos (c)
Zp = Hp × cos (a)
(2)B--C axis type
Xp = Hp × sin (b) × cos (c)
Yp = Hp × sin (b) × sin (c)
Zp = Hp × cos (b)
(3)A--B axis type (A--axis master)
Xp = Hp × sin (b)
Yp = −Hp × cos (b) × sin (a)
Zp = Hp × cos (b) × cos (a)
(4)A--B axis type (B--axis master)
Xp = Hp × cos (a) × sin (b)
Yp = −Hp × sin (a)
Zp = Hp × cos (a) × cos (b)
In the above expressions, a, b, and c represent the positions (angles) of the
A--axis, B--axis, and C--axis relative to the machine zero point; those
values that are present when tool axis direction handle feed mode is set,
or when a reset occurs, are used. To change the feed direction, reenter tool
axis direction handle feed mode, or press the reset key.
