Arm Properties

Fixture Properties dialog box - Arm Properties

The Properties for arms are set in the Properties dialog box.

- Arm Offsets vs Arm1: Defines the location of the given arm in relation to Arm1 coordinates. For example, Arm2 measures the center of a sphere as (X2,Y2,Z2), while Arm 1 will read (X1,Y1,Z1) the arm offset will be (X2-X1,Y2,Y1,Z2-Z1). In the case of Arm1the coordinate values will always be (0.0, 0.0, 0.0), since this is the relationship of Arm1 to itself.

- Mount Point: This provides a clearance position where the machine arm can safely be moved to, after positioning one or all the columns of a fixture.

- Gripper Mount Point: Defines the location where the locator can be safely removed or attached in the case of a manual system.

- Gripper Offsets: Defines the values of the gripper offsets after calibration. The gripper offset is treated the same as a probe offset. The center of the gripper is hereby linked to the machine.

- Safe Move: This specifies the XYZ location that the machine will move to. If you choose to insert intermediate moves, this helps to eliminate collisions in your fixturing sequence. Click the Use Safe Move check box to enable safe moves.

- Probe Angles - Safe A & B: Defines the clearance position of the wrist, when the gripper is enabled.

- Probe Angles - Measure A & B: Defines the measuring position of the wrist, when the gripper is disabled.

- Fixture Volume: Defines the Min and Max values for the fixture volume in terms of XY coordinates. The Approach in negative Y option is used for the slave arms of a master-slave system. Reversing the direction that the slave machine approaches may be needed to cause the machine to move in the correct direction.
