In the figures above, a, b, and c represent the positions (angles) of the
A–axis, B–axis, and C–axis from the machine zero point; those values
present when the tool axis direction handle feed mode is set or a reset
occurs are used. To change the feed direction, reenter the tool axis
direction handle feed mode, or press the reset key.
For tool axis direction determination, the coordinates (rotation angles) of
rotary axes can be set using bits 3 and 4 (3D1X and 3D2X) of parameter
No. 7104, and parameter Nos. 7144 and 7145.
Basic axes X, Y, and Z are determined by parameter No. 1022 (plane
selection). Rotary axes A, B, and C are determined by parameter No.
1020 (axis name).
The direction of the tool X axis is determined by setting bit 0 (TLX) of
parameter No. 7104.
This function is usually used with 5–axis machines. However, 4–axis
machines (One axis is for rotation) can be used by setting bit 2 (CXC) of
parameter No. 7104 to 1.
If either of the two axes selected in type specification based on the axis
configuration is nonexistent as an axis, P/S alarm No. 5015 is issued.
When the tool axis normal direction handle mode is selected and the
manual pulse generator is rotated, the tool is moved by the specified travel
distance in the direction normal to the tool axis tilted by the rotation of
the rotary axis.
