<p>PROBLEM TO BE SOLVED: To provide a processing device and a processing method which enable a work-piece to be processed at high precision even when a temperature change occurs.SOLUTION: A control circuit CONT compares a stored Z initial coordinate with a measured Z coordinate to correct the position of stored #N=first lens transfer surface WKa by a difference factor at step S104 when the difference is determined to be present. Accordingly, even when a thermal expansion occurs in each part of a processing device by a temperature change, the control circuit CONT decides a processing position of the lens transfer surface so as to cancel a thermal expansion factor and can therefore form a lens transfer surface of a constant depth in spite of an environmental temperature change.</p> |
