6.5.7 Cylindrical Surface
Cycles 27 and 28, “Cylinder Surface,” enable the user to machine a contour
on a cylindrical surface (see the User’s Manual).
Prerequisites:
n In MP7510 to MP7530, the center of rotation of a rotary axis must be
defined (see example 3). MP7500 is not needed if only one rotary axis is
present.
n If a PLC datum compensation is used, the same home position must apply
in the description of the machine geometry in MP7510.x to MP7530.x as in
the datum shift.
n After a change in MP7510.x or MP7530.x, the datum must be reset.
