G234 - Tool Center Point Control (TCPC)
(Group 08)
G234 Tool Center Point Control (TCPC) is a software feature in the Haas CNC control that
allows a machine to correctly run a contouring 4- or 5-axis program when the workpiece is
not located in the exact location specified by a CAM-generated program. This eliminates
the need to repost a program from the CAM system when the programmed and the actual
workpiece locations are different.
The Haas CNC control combines the known centers of rotation for the rotary table (MRZP)
and the location of the workpiece (e.g., active work offset G54) into a coordinate system.
TCPC makes sure that this coordinate system remains fixed relative to the table; when the
rotary axes rotate, the linear coordinate system rotates with them. Like any other work
setup, the workpiece must have a work offset applied to it. This tells the Haas CNC control
where the workpiece is located on the machine table.
The conceptual example and illustrations in this section represent a line segment from a
full 4- or 5-axis program.
NOTE:
For clarity, the illustrations in this section do not depict workholding.
Also, as conceptual, representative drawings, they are not to scale
and may not depict the exact axis motion described in the text.
The straight line edge highlighted in Figure
is defined by point (X0, Y0, Z0) and point
(X0, Y-1., Z0). Movement along the Y Axis is all that is required for the machine to create
this edge. The location of the workpiece is defined by work offset G54.
