Secondary Rot. Head
Axis about which the Rotary axis rotates. Specify which linear axis (X, Y, or Z) the Rotary axis rotates around.
Checking this box indicates that the EIA standard for tool motion is adhered to. The EIA standard looks at all motion as if the tool is moving and the work piece is stationary. Check this box if the following is true:
In the XY plane, plus rotation moves the cutter from +X to +Y.
In the ZX plane, plus rotation moves the cutter from +Z to +X.
In the YZ plane, plus rotation moves the cutter from +Y to +Z.
Checking this box indicates that a (0,0,1) tool axis vector positions the rotary axis to zero. Do not check this box if a (0,0,1) tool axis vector will position your rotary axis to 90. Note: This option applies only if your rotary axis rotates around the X axis.
Tool Axis/0,0,1 = 0 (check box)
Tool Axis/0,0,1 = 90 (do not check box)
Pivot point SECONDARY to tool gauge point. Enter the distance from the pivot point of the rotary axis to the tool gauge point of the spindle.
If the secondary rotary axis rotates in an inclined plane (nutator), specify the positive angle of this plane measured from X to Z or Y to Z in a counter clockwise direction.
These check boxes allow the user to select which best represents the format used with the machine's rotary axis:
0 and 359.99...+/- indicates direction
angles are to be output between the values of 0 and 359.99 and +/- indicates the direction of rotation.
0 and 359.99...controller takes shortest path
angles are to be output between the values of 0 and 359.999 and the controller takes the shortest path to the specified location.
-n and +n (n=maximum departure of rotary)
angles are to be output between the minimum and maximum departure values of the rotary.
-359.99 and +359.99
angles are to be output between the values of -359.999 and +359.999.
For every tool axis (for 5-axes machines), there are two solutions available. INTCOM(2094) or IBQUAD can control the selection of the desired position. Defines how the post decide where to move this rotary axis. By default the post takes the shortest path but sometimes users do not want this. This allows the user to define how the post calculates the rotary move.
*******************************CAUTION******************************
If automatic re-position flag is set to find the solution in limits, then IBQUAD has no meaning since,
GPost will always try to select the position that is in limit.

IBQUAD=1 Find B- solution position
IBQUAD=2 Find B+ solution position and also leave C-at last position for (0,0,1)
Note: for head-head mill (CA configuration only), a new option has been added . This check box allows the user to set this for proper optimized calculations.
For 5-Axis head/head machines, the center of the secondary axis may be offset from the primary axis. For example, for a CB machine, the B-axis center of rotation may be at a distance along the Y-axis. The signed distance is measured from the secondary to primary center. This distance is 0 (zero) if they are aligned.
