3. MANUAL OPERATION
314
The tool axis direction handle feed function allows the tool to be moved
through a specified distance by handle feed in the axis direction of the
tool, tilted by rotating the rotation axes.
Tool axis direction handle feed function B provides two functions: tool
axis direction handle feed and tool axis perpendicular direction handle
feed, which performs handle feed in the direction perpendicular to the tool
axis.
By using the tool axis direction handle feed function, the tool can be
moved in the axis direction of the tool by an amount equal to the manual
pulse generator rotation.
Tool axis direction handle feed is enabled when the following four
conditions are satisfied:
(1)Handle mode is selected.
(2)The tool axis direction handle feed mode signal is 1.
NOTE
When both the tool axis direction handle feed mode signal
and tool axis perpendicular direction handle feed mode
signal are 1, neither mode is enabled. In this case, normal
handle mode is set.
(3)In parameter No. 7121, the axis number for the first manual pulse
generator is set as the tool axis direction handle feed mode axis.
(4) A manual handle feed axis is selected for the axis set in parameter No.
7121.
Assume that the rotation axes for basic axes X, Y, and Z are A, B, and C,
respectively. Assume also that the Z--axis represents the tool axis in the
machine coordinate system. Then, depending on the axis configuration
of the machine, four tool axis directions are available. Specify the desired
type with parameter No. 7120.
