A machining test to identify rotary axis geometric errors on a five-axis machine tool with a swiveling rotary table for turning operations [PDF]
Precision Engineering, 2019 Abstract Lately, a cylindrical workpiece of relatively large diameter is often machined by turning operations by a swiveling rotary table in a five-axis machining center. This paper presents a machining test containing features finished by a turning operation by a swiveling rotary table.

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

Novel Rotary Encoder with Multi-Axis Hall Sensors
2023 IEEE SENSORS, 2023 <p>We present a novel high-accuracy rotary magnetic sensor system composed of a two-track coded multi-pole magnet and a dual-spot multi-axes magnetic sensor. The novelty is the measurement of two orthogonal magnetic field components in each of the two sensing spots of the sensor, one associated with each magnet track.

Kinematical Smoothing of Rotary Axis near Singularity Point [PDF]
Materials Science Forum, 2016 This paper deals with singular configurations of a 5-axis machine tool in high speed milling which may lead to the appearance of large incoherent movements of rotary axes near singularity points. These movements generate slowdowns of the actual feedrate during the execution of the tool path, which affect quality and productivity.

Fast Experimental Energy Characterization of a Controlled Rotary Axis
Procedia CIRP, 2016 The goal of the paper is to present a methodology and the related instrumentation for fast energy characterization of industrial machines. Standard energy measurements prescribe acquiring power flowing into the system and into every significant subsystem of the machine using a considerable number of power meters (or repeated measurements) that ...
