Abstract

The authors developed the technique of the study of influence of axial ultrasonic vibrations of a core diamond dressing tool (DT) in the process of dressing of a grinding wheel: on the normal component Py of dressing force, on the wear of the dressing tool diamonds, on the formation of the wheel working surface texture (WWS). The WWS texture parameters were studied by the following methods: sensing on a profile recording instrument using a diamond stylus (parameters are the bearing length ratio tр at the fixed level р and the mean pitch between grains); optical microscopy using the MBS-2 microscope (parameters are the bearing surface ratio η of a grinding wheel). In parallel, the authors carried out the fractographic study of the WWS texture using the LEO 1455VP scanning electron microscope.

The study shows that in the condition of ultrasonic dressing (UD) of a wheel, the DT wear slightly influences the changes in the bearing surface ratio η of the WWS texture. Therefore, the ultrasonic dressing can ensure higher stability of cutting power of a wheel and the DT can work up to wear-out.

The authors give recommendations on the selection of the ultrasonic dressing parameters:

1. It is recommended to select the oscillation frequency from the frequencies specified by the State All-Union standard 16165-80: (18±1.26) kHz; (22±1.54) kHz; (44±3.08) kHz; (66±4.62) kHz.

2. It is impractical to specify the DT amplitude of forced oscillations A higher than 15…20 micron.

3. When selecting the dressing depth tп it is necessary to consider the condition of mandatory intermittent interruption of contact of DT with WWS according to the inequality: 0≤tП≤2A.
