Comparison of tactile and laser-interferometric measurement systems

With the rising precision of machine tools the demand for more precise and more efficient measurement systems increases. At present, several systems with different measurement procedures are available. This article describes three systems for the geometrical characterisation of machine systems: TRAC-CHECK and TRAC-CAL by ETALON AG, and MT-Check by IBS Precision Engineering. A qualitative comparison is made regarding the possibilities of compensation for measured geometrical errors as well as the measurement execution. Furthermore, a metrology frame for the characterisation of the dynamic tool path accuracy, which has been developed at Fraunhofer IPT, is presented briefly.

Order of frictions and stiffnesses…

For lumped systems consisting of different frictions and stiffnesses, there has been confusion in literature about hysteresis curves and virtual play for many decades.

Make it clean

In mid-April, the second edition of the Manufacturing Technology Conference and the fifth edition of the Clean Event were held together, for the first time, at the Koningshof in Veldhoven (NL).

Bringing particles to light

Particle contamination monitoring and cleanliness control are fundamental to micromanufacturing processes across diverse industries to achieve cost-effective production of high-quality and reliable microscale devices and components.
