Abstract
In one embodiment, the present invention includes a sensor having a roller adapted on a shaft to roll along a workpiece surface, a compliant member adapted around at least a portion of the roller, and an encoder to code information regarding movement of the roller. In some implementations, the encoder may be in communication with a processor of a machine to provide information regarding workpiece movement.
Claims19
An apparatus comprising:
- a roller adapted on a shaft, the roller to roll along a surface of a workpiece located in a machine;
- a compliant member adapted around at least a portion of the roller;
- and
- an encoder to code information regarding movement of the roller.

A method comprising:
- contacting a roller of a sensor to a workpiece during operations in a processor controlled machine, the sensor including a compliant member adapted around at least a portion of the roller and an encoder to code information regarding movement of the roller;
- communicating information regarding movement of the roller to a processor of the processor controlled machine;
- and
- controlling operation of a tool assembly of the processor controlled machine based on the information.

A processor controlled workpiece modifying machine comprising:
- a tool assembly to support a tool and provide for movement of the tool;
- a support structure to support a workpiece and provide for movement of the workpiece along a first axis via a first drive member and a second drive member;
- and
- a sensor coupled between the first drive member and the second drive member, the sensor including a roller adapted on a shaft to contact the workpiece during operation, a compliant member adapted around at least a portion of the roller to contact the workpiece during operation, and an encoder to code information regarding movement of the roller.
