Vibration Assisted Conventional and Advanced Machining: A Review

Abstract

Increasing demand for precision miniaturised components made of hard and brittle materials can no longer meet the requirements by conventional machining and advanced machining processes. To facilitate high precision machining, vibration is introduced in any of workpiece, tool and working medium, which is called Vibration Assisted Machining (VAM). In this review, the advancements of VAM in conventional machining as well as in advanced machining are presented. In detail, general overview, classifications, basic kinematics of 1-D and 2-D VAM, chip formation and instrumental implementation issues of VAM, are discussed. In addition to this the reasons for improvements in machining process and promising areas to be explored in VAM are summarized.

Smooth particle hydrodynamics study of surface defect machining for diamond turning of silicon

“…Stress, strain and other internal state variables are evaluated to characterise the material behaviour under loading and unloading conditions. The hydrostatic pressure was measured for different DP parameters β and Ψ values in all the indentation tests, and the values of hydrostatic pressure were found to occur in the range of (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19). Since this range lies in the structural transformation zone of silicon, plastic deformation would be the possible outcome leading to phase transformation in highpressure range with little brittle fracture at low pressures.…”

Effect of particle type and its surface characteristics on the mechanical properties of particle‐filled polymer composite for precision machine tools

“…Ultra‐precision machining (UPM) has been developed as one of the most important techniques in the manufacture of high precision components with a surface roughness of a few nanometers and with a tolerance which is in the submicrometer range . With excellent capability of fabricating high quality components with a nanometer surface roughness, the nanometric surface roughness generated in UPM is easily influenced by a wide variety of factors in a complex cutting process .…”

“…Ultra-precision machining (UPM) has been developed as one of the most important techniques in the manufacture of high precision components with a surface roughness of a few nanometers and with a tolerance which is in the submicrometer range. [1][2][3][4] With excellent capability of fabricating high quality components with a nanometer surface roughness, the nanometric surface roughness generated in UPM is easily influenced by a wide variety of factors in a complex cutting process. [3] These factors including cutting conditions, material pile-up, material swelling and recovery, crystal orientation, material properties, relative vibration between the tool and workpiece, tool vibration, and spindle vibration.…”

Cutting tool holding device with controlled oscillation without external energy source and experimental analysis of its advantages when turning

“…These materials include titanium alloys, unidirectional fibre reinforced composites, hardened die steel, and miniaturised components [2][3][4][5]. Different cases of vibratory (intermitted) cutting are based on the motion of the tool vibration relative to the feed direction (in the normal and cutting directions) and on the tooltip trajectory (ellipse) [2,[4][5][6][7][8]. Moreover, the depths of the cut are small (up to 0.5 mm) for small reciprocating tool movements, and up to 0.05 mm for an elliptical tool motion [7].…”
