Comparison of Volumetric Analysis Methods for Machine Tools with Rotary Axes [PDF]

, 2009
Confidence in the ability of a production machine to meet manufacturing tolerances requires a full understanding of the accuracy of the machine. However, the definition of “the accuracy of the machine” is open to interpretation. Historically, this has

Identification of Geometric Deviations Using Simultaneous Five-axis Control Technique in Five-axis Machining Centers with Double Pivot Spindle Head

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2006
This study was conducted for developing the testing methods by means of simultaneous five-axis motion in five-axis controlled machining centers with a double pivot spindle head. In this paper, the five axis motion was simulated considering the measurement by a ball bar system and the relative distance change between both balls of the table side and the

Influence of interpolation type in high-speed machining (HSM) [PDF]

, 2014
The recourse to the high-speed machining for the manufacture of warped shapes imposes an evolution towards a very high technicality of the CAM methods and of the machining operation execution. Due to its own characteristics, the high-speed machining (HSM)
