3.8 MANUAL ARBITRARY-ANGLE FEED
This function allows a tool to be manually moved in any direction in
any plane. Since the feedrate, feed direction, and feed plane can be
changed at any time, simple surface cutting can be performed
manually.
Explanation
- Selecting a plane
The first and second axes of a plane of manual arbitrary-angle feed are
specified by signals input from external devices.
- Specifying a feed direction
The direction of manual arbitrary-angle feed is specified by a signal
input from external devices. The feed direction can be specified within
a range of 0 to 360 degrees in units of 1/16 degrees. The angle is
specified as shown below. If an angle greater than 360 degrees is
specified, the CNC internally normalizes the angle to an equivalent
angle of up to 360 degrees. The feed direction can be freely changed
during manual arbitrary-angle feed. When the feed direction is
changed, a move command of the new direction is executed
immediately without performing an in-position check.

- Specifying a feedrate
A feedrate for manual arbitrary-angle feed (speed in the tangential
direction) is specified by means of a jog feedrate setting dial. The
feedrate corresponding to the 100% position of the dial is specified in
parameter 1411.
- Starting and stopping manual arbitrary-angle feed
While a manual arbitrary-angle feed signal is held at 1, manual
arbitrary-angle feed is performed. Two types of manual arbitrary-angle
feed signals are supported. One signal causes movement in a specified
direction, while the other signal causes movement in the opposite
direction (180 degrees removed from the specified direction).
