JIG GRINDERS 2
2.2 "C" AXIS PERPENDICULAR TO XY PATH
When it is desired to have the C axis perpendicular to the XY path (JIG GRINDER
type machines), it is necessary to set machine parameter "P622(8)" to "1".
The axes controlled by the CNC will be defined as:
X,Y Main machine axes. It is possible to interpolate them.
C Rotary axis. When this feature is active, the CNC will maintain this axis
perpendicular to the XY path.
U Auxiliary axis that can be interpolated with the X and Y axes.
Also, the following indications must be considered when reading the CNC manuals:
* Any reference to the Z axis must be interpreted as references to the U axis.
* Any reference to the W axis must be interpreted as references to the C axis.
* The following functions are no longer available:
Helical interpolation (with G2/G3)
G17 G18 G19
Plane selection
G33 Electronic threading
G77 G78 Slaving of the 4th to its associated axis
G81 ... G89 Machining canned cycles
G98 G99 Withdraw in canned cycles
Machine parameters “P600(1)” and “P606(1)” must be set to "1" since the "C" axis
must be rotary and "ROLLOVER".
When using this feature, the CNC offers functions M97, M98 and M99 which acquire
the following meaning:
M97 Activates this feature keeping the C axis to the right of the programmed XY
path.
M98 Activates this feature keeping the C axis to the left of the programmed XY
path.
M99 Ends or cancels this feature.
