In the pursuit of 5-axis precision
A super-tuned, but less expensive, machine will perform significantly better than a poorly installed high priced machine. IQL Engineering Services provides solutions for enhancing the volumetric positioning performance of CNC machines. IQL SuperTune is an on-site process that combines low-impact anchoring and precision alignment/adjustment, resulting in high machine stability and optimum positioning performance. New and existing machines can be SuperTuned. IQL SuperTuning can be executed in a few days to minimize production impact. View complete article on American Machinist's website
What Does "eAx for HMC ZzxBm_XzxYxySt" Mean?
Although "eAx for HMC ZzxBm_XzxYxySt" is an odd-looking string of letters, it is an example of precise notation for identifying sources of error in machine tool performance. The naming conventions represented by this example bring order and clarity to one company’s efforts to evaluate and improve machining results. Identifying errors correctly is essential to understanding concepts such as volumetric performance and error budgeting. View complete article on Modern Machine Shop's website
A Better Alternative to Chasing Variability with CAM Software
A study performed by IQL (Independent Quality Laboratory, Rockville, RI) shows that the volumetric positioning accuracy of a popular, moderately priced machine tool can be improved by a factor of 2:1 versus the same machine that was purchased and installed to the manufacturer’s standard specifications. This makes it unnecessary to use CAM software to compensate for dimensional variability within the machine’s measuring envelope. View complete article on MasterCam's website

Machine Tool and Motion Error Standardized Definitions for Simplified Error Modeling [pdf]
by Robert Callaghan
Error models for the purposes of understanding and correcting machine motion errors have been used for many years. Most of these models have been developed to define and improve the behavior of specific laboratory devices or commercial products. The adaptation of Error Modeling for general use in factory applications requires the incorporation of a wide variety of machine configurations. Some of these machines and their errors are described in ISO and ANSI Standards. more...
