Abstract

The mechanisms of frictional chatter of a diamond rulling system and a elastic tool post were researched in mechanical ruling grating processing

and a dynamic model for a mechanical ruling grating was established. Then

the stability of the chatter system was analyzed

and its stability condition and stability threshold were presented. Furthermore

the chatter was researched and analyzed from the energy point of view

and the same stability condition was obtained. A mechanical ruling test were performed with a test device for grating ruling only by changing the ruling speed. After measuring and analyzing the ruling forces

the characteristics of the ruling forces in the vertical direction dropping with the ruling speed were verified

and it satisfied with the precondition for the establishment of frictional chatter. Finally

the surfaces of grooves under four different ruling speeds: 2 mm/s

6 mm/s

10 mm/s and 13 mm/s

were measured

which verifies that the chatter will occur when the ruling speed exceeds the critical value (6-10 mm/s). The experiments confirm the effectiveness of the dynamic model of chatter and the existence of the stability threshold. It provides the theoretical foundation for restraining the chatter during grating mechanical ruling process and deep quantitative analysis.
