Dynamic characteristics of an aerostatic bearing spindle and its influence on surface topography in ultra-precision diamond turning

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

“…In UPM, surface roughness is influenced by many factors, including cutting conditions [3], material pile-up [4], material swelling and recovery [5,6], crystal orientation [7,8], material properties [9,10], relative vibration between tool and workpiece [11,12], tool vibration [13], and spindle vibration [14]. A plethora of research has been conducted on the machinability of non-ferrous materials, such as copper and aluminum, and on chip formation with shear angle in UPM [15][16][17][18][19].…”

“…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.…”

Study on the optical performance and characterization method of texture on KH2PO4 surface processed by single point diamond turning

“…The characterization of texture is an important item of surface quality evaluation. Surface texture also can make known the dynamic behavior of machineworkpiece-tool system, and thus provide guidance for us to find the sources and solutions of texture, in order to improve the surface quality of processed element [3]. Nowadays, most research work about texture is focused on the relationships of surface texture and the friction, wear, lubrication, sealing performance between contact elements [4][5][6].…”

Study on Dynamic Characteristics of Aerostatic Bearing with Elastic Equalizing Pressure Groove

“…Chen et al [10,11] studied the dynamic stiffness and damping coefficient of the aerostatic bearing and pointed out that the frequency dependence of the dynamic performance of the bearing is more obvious under the micro gas film gap and the high gas supply pressure. Some other scholars have also studied the dynamic characteristics of aerostatic bearings [12][13][14].…”
