Abstract

Presented is the automated measuring test stand based on the modified Haas VF-2YT machining center. That allows conducting experimental research of conventional and assisted with workpiece ultrasonic oscillations grinding processes (UAG). Respective measurement paths and automated measurement data acquisition process during the experimental research was discussed. Particular notice was given to grinding force components measurement system.

Highlights

  • In the face of machining continuously developed, hard and brittle materials, conventional grinding techniques are appearing less efficient in modern times

  • The Haas VF-2YT vertical machining center was used as the basis for the test stand, prepared for the needs of the PBS2/B6/17/2013 project [4], for studies the grinding processes assisted with workpiece oscillations

  • As a result of all modifications of the base machine tool, a unique four-axis diagnostic test stand was created to study conventional grinding processes and processes assisted with workpiece oscillations

Presented is the automated measuring test stand based on the modified Haas VF-2YT machining center. That allows conducting experimental research of conventional and assisted with workpiece ultrasonic oscillations grinding processes (UAG). Conducted research indicates advantageous influence of introducing workpiece ultrasonic oscillations to conventional grinding process on tool life, surface quality and grinding force values [1,2,3]. In order to obtain credible results, it is necessary to conduct adequate amount of measurements for many input parameters (grinding wheel peripheral speed, feed rate, grinding depth, vibration amplitude, vibration direction, etc.). It significantly expands experimental design which impose automation of measuring data acquiring and analyzing process to ensure its efficiency. The third system was responsible for measuring the surface roughness obtained after each machining pass [4]
