3.9.3 Rotational Handle Feed Around the Center of the Tool Tip
Select the mode of rotational handle feed around the center of the tool
tip and rotate the handle of the manual pulse generator. When the
rotation axis (A-, B-, or C-axis) is moved, the X-, Y-, and Z-axes are
adjusted so that the movement of the rotation axis does not shift the tool
tip.
If this mode is selected in the manual handle interrupt mode in
automatic operation, rotation around the center of the tool tip by the
manual pulse generator is superimposed on the movement by automatic
operation.
P1 (Tool tip position)
02
01 (Tool rotation center)
With the relative relationship between the
tool tip position (P1) and workpiece held as
is, the rotation axis is turned while the X-, Y-,
and Z-axes are adjusted so that the tool
rotation center moves from 01 to 02.

Rotational Handle Feed Around Tool Tip
Procedure
1 Select the HANDLE switch from the mode selection switches.
2 Select the rotational handle feed around tool tip switch.
3 Select the rotational handle feed around tool tip mode axis as the
handle feed axis for the first manual pulse generator (parameter
Nos. 7554, 7555).
4 When the handle is turned, the tool rotates around the tool tip by
the corresponding distance.
When the tool direction handle feed mode and tool axis right-angle
direction handle feed mode are selected, neither mode is set, but the
ordinary handle mode is set.
The procedure above is only an example. Refer to the relevant manual
published by the machine tool builder for other possible operations.
Explanation
- Pulse distribution to basic axes
In the case of rotation around tool tip, linear axis movement (Xp, Yp,
Zp) calculated by the equation below is output simultaneously with
rotation of the rotary axis. As a result, the tool tip position hardly
moves. (The tool tip may move when the rotary axis is rotated at high
speed.) The pulse distribution to basic axes by rotational handle
