TLDR
In this article, a new system for increasing CNC machining productivity is described, which is based on registering the moment when the cutting tool touches the workpiece during a machining operation.Abstract:
In this paper a new system for increasing CNC machining productivity is described. The system is based on registering the moment when the cutting tool touches the workpiece during a machining operation. The cutting tool approaches the workpiece with rapid traverse and switches to work feed when it comes in contact with it. In this way, the time for ‘cutting air’ can significantly be reduced.read more

Thermal characteristics of composite sandwich structures for machine tool moving body applications
Jung Do Suh,Dai Gil Lee +1 more
TL;DR: In this paper, the thermal properties of composite sandwich structures for machine tool parts were investigated both by FEM analysis and experiment, and the reliability of adhesive joints between the composite sandwich and the steel structure was investigated in terms of adhesive joint strength and thermal stress induced by heat generation of linear motors.

Qualimetry as productivity criteria in metal-cutting operations.
TL;DR: In this article, the authors developed methods for measuring the performance of metal-cutting machines and open the way to create a regulatory framework based on quantitative indicators of the equipment quality, which is essential that the quali-power of the machinery is an objective indicator of its quality, independent of specific conditions of its operation at any given time.

Machining precision augmented by sensors
TL;DR: In this article, two types of on-machine measurements are conducted between successive cutting passes, one providing a reference position of the tool-tip using diffraction measurements, and the second measurement type is by the tooltip acting as a probe of a 'fine touch' contact sensor that is under proximity control while approaching the part.
