Development of an Experimental-Analytical Method for Determining Temperature Deformations of End Measures for Length in the Nanometer Range

Estimation of Error in Determining the Centers of Rotation of Links in a Kinematic Chain for Industrial Robot Calibration Techniques

“…Any calibration of an industrial robot includes a procedure for determining the actual values of control parameters and their communication to the control system (control model). Analysis of the research over the last 5 years shows that the problem of developing the methodology for this operation has received insuffi cient study [4][5][6][7][8][9][10][11][12][13][14][15][16]. This article discusses the fi rst stage of calibration, namely, the method of determining the actual values of the coordinates of the centers of rotation of the links in the kinematic chain of an industrial robot -centers of the degrees of freedom (DF).…”

Comparative Analysis of Thermal Deformations in Structural Elements of Measurement Stands and Supports

“…Tests for exposure to ambient climatic factors should be carried out only when stands and supports are transported. Procedural guidelines [3] propose the selection of measurement devices with inductive transducers (linear displacement transducers) attached to them; however, standards documents provide no recommendations for selecting and using such attachments to carry out precision measurements in the nanometer range.The authors had previously proposed and approved a method for determining thermal deformations in measurement stands from the change in position of the point of contact between the test lead of an inductive transducer and the measured object [1,4]. The procedure called for the adoption of measures in which the temperature coeffi cient of linear expansion was an order of magnitude smaller than that of the measurement system.…”
