Machine Tool Calibration

Our Machine Tool Services

For nine years, our expert services team has calibrated hundreds of machine tools for customers around the world. The industries and applications are varied with differing environments, accuracy requirements, space limitations and time constraints. Many customers have their machines calibrated every six months to one year, or after maintenance.

API service technicians are experts in standard laser alignment. We manufacturer our own laser equipment, so we know it works. We also provide volumetric compensations that ensure the best achievable accuracy throughout the machines entire workspace. Our personnel are not only proficient in laser alignment and calibration, but they are also experts with the machine controllers. API provides solutions to partners Siemens, Fanuc, Fagor and others.

Volumetric Machine Tool Calibration

API’s approach to the volumetric calibration solution consists of a precision laser tracker with interferometry capability. The interferometer feature of the laser tracker is the same technology traditional laser systems used for years to successfully calibrate machine tools. Coupling the interferometry technology with a laser tracker offers the added capability to track the machine’s tool-tip location through extensive axial movements throughout the entire volume of the machine.

Using the laser tracker and active target, the VEC method measures all 21 error parameters for 200–400 points within the machine’s working volume with all possible machine poses, even with the rotary axis. Each point becomes an accurate reflection of the machine’s kinematic errors. A complex algorithm is used to decouple error sources and build an extremely accurate volumetric map. Error compensation is done by adding the compensation from the entire measured axis to get the best tool-tip position.

Besides the measuring system, the API solution also includes a sophisticated proprietary calibration software that uses a polynomial equation-based, kinematic model of the machine to map errors throughout the volume. To compensate the machine in real time, the software resides on the machine’s controller or on an industrial computer that directly interfaces with the controller and machine tool.

In summary, the software uses the measurements from the laser tracker and active target and develops compensation values to drastically reduce machine errors. Once the machine is put back in production, the software runs in the background, monitors the programmed tool path, and applies for real-time compensations automatically to the tool tip.  Typical machine improvements are 4 – 5

Laser Alignment for Machine Tools

Using laser alignment you can keep your machine tools in good working order by ensuring proper alignment. The value of this small investment cannot be overstated. Machine tools lacking proper alignment and pitch error compensation are not fully productive. Over time, these errors become magnified in faulty machine operation and substandard parts. API Services offers the most economical and efficient laser alignment solutions for your machine tool. API Services recommends a baseline reading of alignment for all service work and regular checks and adjustment as part of any ongoing preventive maintenance program. Recalibration, including a review of machine alignment, is also critical following any machine repair.
