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)
O2
O1 (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.
Workpiece
Tool tip center rotation handle feed is enabled when the following four
conditions are satisfied:
(1) Handle mode is selected.
(2) Tool tip center rotation handle feed mode signal RNDH is set to 1.
(3) In parameter No. 7554 and No. 7555, the axis numbers of the first
manual pulse generator are set as the axes for tool tip center
rotation handle feed mode.
