Calibrating machine tools to generate complex shapes - optically scanning to provide data for comparison with reference e.g. for dental crown

摘要

The blank material (8) is supported on a spindle and can be moved axially. Located on either side machining tools (11, 12) can be moved in a precision control mode to form the required profile. The form of the object can be obtained by creating a shadow on a group of CCD cells (72) when an i.r. source (71) is used. USE/ADVANTAGE - Precise calibration for dental mechanic.
