Sigma optical machine automatic swing slide accuracy measurement

This article will focus on the automatic swing slide table and introduce some key indicators of the Sigma optical machine's automatic swing slide table.

Accuracy measurement indicators for automatic swing slide table

1、 Position accuracy

repeatability

At any position on the slide table, perform multiple positioning from the same direction and calculate the maximum deviation value of the stopping position.

Define the maximum value in its numerical value as the repeat positioning accuracy.

Swing center height

The distance from the ideal swing center to the tabletop.

Accuracy of swing center position

The maximum deviation range between the actual swing center position and the ideal center position during the full stroke of the swing slide table.

noncutting stroke

At any position on the slide table (both ends or center, etc.), perform multiple positioning from the positive and negative directions, and calculate the average deviation of the stopping positions at each point.

Define the maximum value as an empty trip.

2、 Attitude accuracy

扭矩刚度

We define the angular displacement of the sliding table under unit torque load as its torque stiffness.

3、 Minimum Displacement (MIM)

We define the minimum achievable movement resolution as the minimum displacement when positioning at three specific positions on the slide table (both ends and the center).

Verification method: Instruct the slide table to move 10 points in the positive and negative directions at each position and measure the corresponding amount of movement.

During the measurement, precision small displacement sensors and automatic collimators were used separately.
