Machine Tool Calibration

After the alignment of a machine tool has been inspected / adjusted to the manufacturers specifications (see alignment), it is possible to benefit from axis positioning measurement / compensation.   CNC Services calibrates its customer's equipment with an Optodyne dual beam MCV-4000W laser calibration system.   With this system, CNC Services can measure linear positioning, pitch, yaw and perpendicularity of axis travel.

The annual calibration of this unit was on August 6, 2002 in compliance with ISO/IEC 17025.   A copy of the Report of Calibration can be provided to the Quality Control department to meet the accuracy tractability requirements that the company has established.

Unlike many companies offering measurement and compensation services, CNC Services has an experienced CNC Field Service Engineer providing this service.   This CNC Field Service Engineer is capable of diagnosing and repairing any problem on the machine.   If there is a problem that needs to be repaired before compensation values can be entered in the control, CNC Services can perform the repair.   

This is a great advantage for the customer.   One supplier can measure, diagnose / repair if necessary, re-measure and compensate to complete the job.   Using two suppliers lengthens the downtime of the equipment and increases the total cost of the services received.

Example:

The calibration service advises the customer there is a problem in the machine and leaves.   The repair service comes, fixes the problem and leaves.   The calibration service returns to measure and compensate the machine not fully aware of the work the repair service has provided.   If there are any additional problems discovered by the calibration service that prevent the measure and compensation from being completed, the cycle repeats itself.

This is not an exaggeration!   Before CNC Services owned a laser, they were at a customer site providing field service while a laser calibration service was checking machines.   One of the machines had a loose gib.   The calibration service was going to pack up, leave and return when the gib was adjusted.   The customer came to me and I suggested the calibration service be given a break for about 2 hours while I adjusted the gib.   This was done and the customer was saved the cost of a return trip and a second setup by the laser calibration service.

Before CNC Services would begin a laser measurement, there would be several checks made with conventional measuring tools (indicator, level and square).   These checks are quick and provide information that will indicate if the machine tool is prepared to be measured by the laser (see alignment).
