Angular measurements are made at multiple points along a machine’s travel path to test for rotation about an axis perpendicular to the axis of motion (pitch and yaw).
- A common cause of machining errors, geometry errors are as critical as linear positioning errors.
- Unwanted angular motion in a machine tool causes positioning errors that reduce the overall accuracy of your machine.
- Positioning errors over the work zone can be estimated from the angular and linear.
- The condition of ways and the range of squareness and parallelism in the work zone can be indicated by angular measurements.
- Angular measurements help find the causes of linear positioning errors and can be useful in making decisions about whether to replace or rebuild older machines.
- Long-term drift tests can be performed over hours or days, showing possible effects of temperature on geometry.
