In this paper we present two contributions to improve accuracy and speed of an image
search system based on bag-of-features: a contextual dissimilarity measure (CDM) and an …

A simple method for simultaneously measuring the 6DOF geometric motion errors of the
linear guide was proposed. The mechanisms for measuring straightness and angular errors …

This paper suggests a method to reduce the machining errors of a three-axis machine tool
by implementing an on-machine measurement with a touch probe. Probing errors of a touch …

In this work, a methodology for the estimation of the geometrical accuracy of five-axis milling
centres is developed by using the well-known formulation proposed by Denavit and …

It has been proved that error compensation is an effective approach to improve machining
accuracy of a machine tool cost efficiently. In this paper, the framework of an error …

The increasing environmental and health concerns of conventional emulsion flood coolants
have motivated the use of vegetable oil in the form of minimum quantity lubrication (MQL) in …

A novel method for simultaneously directly measuring six-degrees-of-freedom (6DOF)
geometric motion errors of CNC machine tools was proposed, and a corresponding …
