SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)
Feedrate Override:
The per minute feed can be overridden using the feedrate override button on the machine
operator's panel by 0 to 140% (per every 10%). Feedrate override cannot be applied to functions
in which override is inhibited (e.g. tapping cycle).
Polar definition of a line
A polar line is specified by a polar radius/length (R), an angle (AB), and a polar center (AA or I,
J, K, or XC, YC, ZC).
Polar definitions are valid in any plane. The 3 o'clock position is always 0°. Positive angles result
in CCW rotation (from 0°) of the polar radius, while negative angles result in CW rotation (from
0°) of the polar radius. Polar lines can be used when estimating lengths during trig help. If the
polar radius/length (R) or angle (AB) is not specified, the previous values will be used. If the
polar center is not specified, it is taken to be the current machine position. Some examples
follow.
