A problem of optimal cylindricity profile matching

Abstract

Abstract. The bird-cage strategy used for measuring cylindricity is reported to be the most effective, as it provides the most detailed information about an analyzed object. The average values of profiles measured with the cross-section and the generatrix strategies may differ slightly, yet this may result from some design imperfections of the measurement instruments used. In this study, the problem of optimal profile matching is formulated and solved. As a result, the differences between the values of the registered profiles at the points of intersection of the scanning trajectories can be minimized.

Influence of the cutting parameters on the workpiece temperature during face milling

“…guides, proximity face seals, pneumatic valves [20][21][22][23][24][25][26][27], and precision devices used to control flying objects [28][29][30]. Increased temperature of the processed object during processing may lead to changes in the structure of the surface layer [31][32][33], decrease of processing accuracy [15][16][17][18][19], [34,35] related to thermal expansion of the processed material, as well as its deformation [36,37] resulting from uneven heating. Mistakes in performance of precision parts caused by uncontrolled heating of the processed object during face milling may result in improper operation of the device e.g.…”

Study of the effect of temperature on the positioning accuracy of the pneumatic muscles

“…Because of the unique functional characteristics of artificial muscle drives when compared to conventional pneumatic actuators, they are used as drive elements in anthropomorphic robots, bionic and humanoid bioprosthetics, manipulators used for rehabilitation and physiotherapy, and more often in the automation of production processes [21][22][23][24][25][26][27][28][29][30][31]. Pneumatic artificial muscles PAM can be compared with single-acting actuators due to the way they function [32].…”

The impact of cooling methods on the maximum temperature of the processed object during side milling

“…[24][25][26]. It may, additionally, cause deformation of the processed object and the tools [27][28][29][30][31][32][33][34][35]. Excessive amount of heat delivered to the tool results in a loss of cutting properties of the tools and, consequently, in damaging the tool, which has a significant impact on production costs and efficiency of performed processing.…”
