Machine Tool Error Compensation

Machine Tool Error Motions

A major part of a precision machine tool system is its control system, and more importantly the ability to apply error compensation. With a stiff and repeatable base mechanical system, high resolution transducers and the application of precision metrology it is possible to accurately correct the errors in a machine tool system to give significantly reduced error motions.

By calculation of measured error motions and accurate measurements it is possible to correct for a large number of geometric and dynamic error motions that can occur in a machine tool system.

Accurate machine tool metrology and error compensation is what turns a good machine tool into an excellent machine tool. Cranfield Precision has vast experience in machine tool metrology and in the application of advanced error compensation techniques. This is made possible through our advanced CNC control system, allowing for complex error motions to be effectively compensated.

CNC6400 - Advanced CNC Control System

CNC 6400 Control System

The CNC 6400 Control System is Cranfield Precision's flagship CNC Control System.

Cranfield Precision has a history of producing advanced control system technology and was the first to control company to create a camshaft following profile to produce a master cam revolutionizing the automotive industry.


Cranfield Precision's EGB (Electronic Gear Box) allowed for the precise synchronization of multiple machine axes allowing complex motions to be produced very accurately.


There are numerous advantages of having a precision machine tool company with their own CNC control system software rather than using 3rd party vendor control systems. With an in-house software team it is possible to quickly and effectively tailor the control system to meet specific machine and process requirements.


Today Cranfield Precision employs advanced control system techniques and uses modern control hardware capable of producing some very complex and accurate machine tool motions.

Cranfield Precision are at the 26th Annual Meeting of the American Society for Precision Engineering (ASPE)

The 26th Annual Meeting of the American Society for Precision Engineering is happening between Sunday and Friday the 13th to the 18th of November 2011 at the Denver Marriott City Center Hotel, Denver, CO, USA.

Cranfield Precision is attending the conference and will be represented by Mark Stocker, division manager.

Come and talk to us about your complex manufacturing challenge or general precision engineering related topic.
