3.2.2.55 G140/G141/G142 Noncircular grinding "on"/"off"
The functions G140 ... G142 are used to switch the "Noncircular grinding"
function on or off.
G140
G141 X C D L K E
G142 X C D L K E
X Total overmeasure in mm
C Start area of the positioning as a position of the angle axis (with L=0 only).
If it is not programmed, the start area of the positioning is defined by the
starting position of the C axis
D Grinding wheel diameter. If it is not programmed, the current diameter is
taken from the tool data.
L Profile
0: constant (default)
1: not constant
K Noncircular grinding
0: without correction table (default)
1: with correction table (see G144, G145)
E Noncircular grinding
0: from outside (default)
1: from inside
G141 is used to switch on the "Noncircular grinding" function, namely with
a negative direction of rotation of the C axis during the profile creation. G142
activates noncircular grinding with a positive direction of rotation.
G140 switches the "Noncircular grinding" function off again.
The individual grinding phases are called by G143, with the description of
the finished profile as a subprogram, between G141/G142 and G140. The
rotational direction of the profile description must match the rotational
direction defined by G141 or G142.
