HEIDENHAIN CNC Pilot 4290 - Manual (Page 122)

4 DIN PLUS 110
Approach to tool change position G14
The slide moves at rapid traverse to the tool change position. In setup
mode, define permanent coordinates for the tool change.
Parameters
Q:
Sequence – default: 0
0: diagonal path of traverse
1: First X direction, the Z
2: First Z direction, then X
3: Only X direction
4: Only Z direction
Programming in the Y axis See ”CNC PILOT 4290 with Y Axis”
User's Manual.
4.6 Machining Commands
4.6.2 Tool Positioning without Machining
Rapid traverse G0
The tool moves at rapid traverse along the shortest path to the target
point
Parameters
X, Z: Diameter, length to target point (X diameter)
Programming X, Z: Absolute, incremental or modal
Programming in the Y axis: See ”CNC PILOT 4290 with Y Axis”
User's Manual.“
4.6 Machining Commands
4.6.1 Assigning the Contour to the Operation
Workpiece group G99
If more than one contour description is defined in an NC program
(workpieces), use G99 to assign the ”contour Q” to the following
machining sequence. The slide code before the NC block defines the
slides that machine this contour. If G99 was not yet programmed (for
example at the start of the program), all slide work in ”contour 1.”
Parameters
Q:
Tool number – specified in CONTOUR
D: Spindle number – spindle that holds the workpiece
X, Z: Zero point shift (reference: machine zero)
■ The simulation
– positions the tool using the ”shift in X, Z”
– calculates and positions the chuck using
the ”spindle number D” (G99 does not
replace the G65)
■ Program G99 again if the workpiece is
transferred to another spindle and/or
moves its position in the working space.
