Investigation on the influence of tool-tip vibration on surface roughness and its representative measurement in ultra-precision diamond turning

A review of machine-tool vibration and its influence upon surface generation in ultra-precision machining

“…A physical pendulum model was proposed to explain why the high twin-frequencies for tool-tip vibration were induced by damping. The relationship between the tool-tip vibration and the resulting periodic fluctuation of the surface profile was also established [13,35]. Moreover, the relationship between the two basic physical phenomena (tool-tip vibration and shear band formation) in ultra-precision diamond turning was described by a dynamic model [16].…”

“…Zhang et al [33,34] found that in UPM the frequency range covered from dozens of Hz to dozens of kHz. Based on the physical origins of vibration, the vibration in UPM can be categorized into tool tip vibration [13,16,[33][34][35], spindle vibration [14,[36][37][38][39][40], material induced vibration [32], tool hold vibration, slide vibration and table vibration; all would affect surface roughness and form error. However, the vibration in UPM has not been understood fully.…”

Form error in diamond turning

“…The possibility of chatter in diamond turning has been ruled out by them [7] since the depth of cut in ultraprecision machining is usually in the range of a few to several tens of micrometers and the chatter vibration induced by the regenerative effect seldom occurs as it is generally developed under heavy-duty cutting. However, some high frequency marks (12 kHz to 14 kHz) on the cutting force signal and surface roughness profile have recently been reported in the cutting direction which is believed to be from the tool-tip vibration [8] during SPDT.…”

“…Surface roughness after a polishing also is one of the most important criteria used to evaluate the performance of the polishing tool [17,18]. Results are measured using Veeco Wyko NT1100 (5× magnification, phase-shift mode, sample 0.92 mm × 1.2 mm) with the same process parameters, as shown in Fig.…”
