Axis Configuration (1)
The generated cylinder surface curve transformation allows a traversing path to be specified
with respect to the generated surface of a cylinder coordinate system. The machine
kinematics must correspond to the cylinder coordinate system. It must include one or two
linear axes and a rotary axis. The two linear axes must be mutually perpendicular. The rotary
axis must be aligned in parallel to one of the linear axes and intersect the second linear axis.
In addition, the rotary axis must be co-linear to the cylinder coordinate system.
If there is only one linear axis (X), only grooves which are parallel to the periphery of the
cylinder can be generated. In the case of two linear axes (X,Z), the groove pattern on the
cylinder is optional.
Axis Configuration (2)
Figure 7-11
If a third linear axis is available which can produce a right-handed Cartesian coordinate
system with the other two linear axes (axis configuration 1), then it is used to offset the tool
parallel to the programmed path by means of tool radius compensation. thereby allowing
grooves with rectangular traversing section to be generated.
