#### MachineDefinition – Movement Tab

MachineDefinition dialog box – Movement tab

The Movement tab of the MachineDefinition dialog box, allows you to define the codes needed to specify whether or not the NC machine can perform unprotected moves, set work planes, or enable circular moves.

Note: The Default button for each item below sets the appropriate NC codes in the boxes for the selected controller. You can then modify or replace these codes as needed.

Linear Movement area:

Protected – This box allows you to define the controller codes required to perform a move so that the probe detects collisions.

Unprotected – This box allows you to define the controller codes required to perform a move so that the probe does not detect collisions.

The values of the Linear Movement area set by default from the Wilcox Macro group selected from the "MachineDefinition – Measure Tab".

Set Circular Move Plane area:

XY Plane – This box lets you define the controller codes that set the XY workplane (for example, G17).

XZ Plane – This box lets you define the controller codes that set the XZ workplane (for example, G18).

YZ Plane – This box lets you define the controller codes that set the YZ workplane (for example, G19).

Circular Movement area:

CW Arc – This box lets you define the controller codes that allow movement in a clockwise direction.

CCW Arc – This box lets you define the controller codes that allow movement in a counterclockwise direction.

Allow Unprotected Linear Moves: Selecting this check box allows unprotected linear moves. To generate unprotected moves, use the CNC/SETPROTECTION,NO command inside the Edit window of PC-DMIS NC.

It is recommended to uncheck this option for all machines. PC-DMIS NCI uses protected moves as defined in the Linear Move macro for all XYZ moves.

Allow Circular Moves: Selecting this check box allows circular movement. The normal motion approximates circular moves with straight line moves. Circular moves are unprotected, so Unprotected Linear Moves must also be checked to allow circular movement.

Unchecked. PC-DMIS NCI does not use Circular Moves. PC-DMIS will interpolate a circular move as multiple straight line moves.
