15.1.14 "C" axis: Machining of the turning side of the part
Machining on the turning side is activated and deactivated with the
instructions
#CYL
and
#CYL OFF
. For this type of machining either a
rotary axis or a spindle may be used as "C" axis.
• When using an axis, it is activated as "C" axis after defining the
plane with the
#CYL
instruction.
• When using a spindle, it must be activated as "C" axis in advance
using the
#CAX
instruction.
#CYL It activates machining of the turning side of the part.
It activates the machining of the turning side and it defines the work
plane. The axis to be activated as "C" axis will be determined by the
work plane defined.
The programming format is:
#CYL [<abs>,<ord>,<long><radius>]
Programming the radius is optional. If not programmed, it assumes as
the cylinder radius the distance between the rotation center and the
tool tip. This makes it possible to develop the surface on cylinders with
variable radius without having to indicate the radius.
The "C" axis will be programmed as if it were a linear axis (in
millimeters or inches) and the CNC will calculate the corresponding
angular movement depending on the selected radius.
To activate an axis or spindle as "C" axis, it must have been defined
as such by the machine manufacturer (
CAXIS
). Depending on the
machine configuration, it may be necessary to define the relevant
kinematics (
TYPE 43
).
Although the machine may have several axes defined as "C" axis, only
one of them may be active.
