- Tool tip center rotation handle feed
The tool tip center rotation handle feed is enabled when the following
four conditions are satisfied:
<1> Handle mode is selected.
<2> The tool tip center rotation feed mode signal (RNDH) is set to
"1".
<3> The state of the first manual handle feed axis selection signals
(HS1A - HS1E) to make the tool tip center rotation handle feed
mode effective is set in parameter No.12313 or No.12314.
<4> The value of parameter No.12313 or No.12314 matches the first
manual handle feed axis selection signals (HS1A - HS1E).
- Amount of movement
When the manual pulse generator is rotated, the rotation axis is moved
by the amount of rotation. The linear axes (X, Y, and Z axes) are
moved so that turning the rotation axis does not change the relative
relationship between the tool tip position and the workpiece.
- Feedrate clamp
The feedrate is clamped so that the synthetic speed of the linear axes
(in the tangential direction) does not exceed the manual rapid traverse
rate (parameter No.1424) (of any moving linear axis). The feedrate
is also clamped so that the speed of the rotation axis does not exceed
the manual rapid traverse rate (parameter No.1424) (of that particular
axis). Handle pulses generated while the clamp feedrate is exceeded
are ignored.
- Tool tip center rotation JOG feed/tool tip center rotation incremental feed
The tool tip center rotation JOG feed or tool tip center rotation
incremental feed is enabled when the following three conditions are
satisfied:
<1> JOG mode or incremental feed mode is selected.
<2> The tool tip center rotation feed mode signal (RNDH) is set to
"1".
<3> The feed axis direction selection signal (+Jn, -Jn (where n = 1 to
the number of controlled axes)) is set to "1" for the rotation axis
to be rotated.
Ex.) When the B-axis (4th axis) is rotated
• +J4: Tool tip center rotation feed +
• -J4: Tool tip center rotation feed -
- Feedrate
Control is exerted so that the synthetic speed of the linear axes (in the
tangential direction) is the dry run rate (parameter No.1410). The
manual feedrate override feature is available.
If bit 2 (JFR) of parameter No. 12320 is set to 1, the feedrate of a
rotation axis is the jog feedrate of the axis to be rotated (parameter No.
1423). The manual feedrate override feature is available.
