#### MachineDefinition - Physical Tab

MachineDefinition dialog box – Physical tab

Machine Limits area:

XYZ Minus / Plus – These boxes define the travel limits for each axis in machine units. If these boxes contain zeroes, then limit checking will be bypassed at CNC program generation.

Note: These values are in machine coordinates and NC programs are in work offset coordinates, Meaningful range checking can not be performed unless reasonably accurate values for the nominal work offset are supplied in the PC-DMIS command, CNC/USEWORKOFFSET.

CNC Address – These define the location of the controller register containing the limits for each axis. The exact value of the axes limits are stored here when measurement is taken.

Max Velocity – This box specifies the maximum travel velocity in machine units/Minute. The feed rate for positional moves will be the product of this value and the move speed percentage set in PC-DMIS parameter settings.

Rotary Table (Cnc Coordinates) area:

Number of – Specifies the number of Rotary tables.

Max Velocity - This box specifies the maximum travel velocity in the rotary table in degrees per second.

CNC Axis – This box defines the axis identifier for the rotary table.

Minus / Plus Limits – These boxes specify a rotary table's limits. If these boxes contain zeroes, then limit checking will be bypassed at CNC program generation.

CNC Address – This box defines the location of the controller register containing the position of the rotary table. The exact value of the rotary table angle is stored here when a measurement is taken.

CNC Address = 0 will disable this function. For Fanuc controllers, this is the address of the Absolute Position Register if a rotary table is configured.

Unlock – This box allows you to specify a command string required for the controller to unlock the rotary table. This field is left blank if no rotary table is present, or the table does not require unlocking.

Lock – This box allows you to specify a command string required for the controller to lock the rotary table. This field is left blank if no rotary table is present, or the table does not require locking.

Wrist area:

Number of Axes – The number of axes in a machine tool head or wrist

Up to two joints can be configured with axis label and direction. The joints are attached to the Z axis ram. A compatible wrist definition is required in Probe.dat or UsrProbe.dat in PC-DMIS.

Joint Axis – The letter used in the NC program to move the wrist axis.

Reverse – Check to reverse the direction of motion to correlate with PC-DMIS.

CNC Address – This box defines the location of the controller register containing information for the Wrist axis. The exact value of the rotary table angle is stored here when a measurement is taken.

U nlock – This box allows you to specify a command string required for the controller to unlock the wrist axis. This field is left blank if no wrist axis is present, or the wrist does not require unlocking.

Lock – This box allows you to specify a command string required for the controller to lock the wrist axis. This field is left blank if no wrist axis is present, or the wrist does not require locking.
