“…The tip-to-sample distance in EFM is on the order of 100 nm during the scanning, which is more than ten times larger than that in a scanning tunnelling microscope (STM) [236] [82] and is large enough to avoid collision of the tip with the sample surface. In addition, pneumatic sensors [83] and ultrasonic sensors [213] are other types of noncontact sensors for on-machine surface metrology.…”

On-machine and in-process surface metrology are important for quality control in manufacturing of precision surfaces. The classifications, requirements and tasks of on-machine and in-process surface metrology are addressed. The state-of-the-art on-machine and in-process measurement systems and sensor technologies are presented. Error separation algorithms for removing machine tool errors, which is specially required in on-machine and in-process surface metrology, are overviewed, followed by a discussion on calibration and traceability. Advanced techniques on sampling strategies, measurement systems-machine tools interface, data flow and analysis as well as feedbacks for compensation manufacturing are then demonstrated. Future challenges and developing trends are also discussed.

“…Beekhuis et al [15] proposed a method based on controlling the cutting depth of the clamped thin-walled part. Stöbener and Beekhuis [16] have applied an in-situ ultrasonic measuring system to compensates wall thickness variations during turning operations. These methods could reduce wall thickness variation of parts clamped inside, nevertheless, clamping parts outside could prevent accurate measurement of wall thickness due to jaws.…”

Estimating bore profile is important to select an appropriate tool for precision manufacturing in the process planning stage. Also, it helps in reducing the rejection rate of the process. A manufacturer might not be well-equipped and want to make their best with the resource on hand. Three-jaw chuck allows machining a wide range of workpiece, mostly circular parts in a lathe. However, clamping via a three-jaw chuck distorts the workpiece. In this study, the deformation of the bore profile was investigated numerically for circular parts. Finite element analyses were performed to examine dimensional variation for various materials and different wall thicknesses under fully elastic plane stress conditions. The stressed workpiece had a triangular form. Results showed that wall thickness and materials are important parameters on the triangulation of bore diameter. A simple calculation method based on thick-walled vessel theory was proposed to estimate the tolerance grade of the workpiece. This simple method provides the opportunity to reduce the rejection rate in the mass production of circular parts.

“…Precision hard turning requires highly precise machine tools to eliminate the form and dimensional errors induced by the moving components of a machine tool such as the spindle, the slide bed and the tail stock. [7][8][9][10][11][12][13] The surface roughness is one of the most important requirements in a machining process, as it is considered to be an indicator of the product quality. It indicates the irregularities of a surface texture.…”

“…The effects of clamping techniques on the deformations of thin-walled rings have been investigated by many researchers. [7][8][9][10][11][12][13] Geometric errors mostly result from the inaccuracy of tooling parts, such as inserts, tool holders and clamping devices. 12 An investigation suggested that after replacing an insert, the repeatability errors at the tip of the insert can reach up to several microns, and the displacement of a tool tip under a cutting load can also reach several microns.…”

This paper is focused on optimizing the cutting conditions for the surface roughness, inner-diameter error and roundness obtained in hard turning of an inner ring bore. The hard-turning experiments were conducted on hardened and tempered AISI 52100 bearing rings using the L9 orthogonal array on a CNC lathe. The cutting speed, feed rate and number of the machined part were selected as control factors. The optimum cutting conditions were determined using the signal-to-noise (S/N) ratio. S/N ratios were calculated using the lower-the-better approach. An analysis of variance (ANOVA) was also employed to determine the level of the effect of the control factors for the surface roughness, inner-diameter error and roundness. The statistical analysis showed that the feed rate was the most significant factor for the surface roughness while the cutting speed was the most significant factor for the roundness and inner-diameter error. Finally, the optimum cutting conditions were further confirmed with confirmation tests. Keywords: diameter error, hard turning, roundness, surface roughness, Taguchi method lanek je osredinjen na optimiranje razmer pri rezanju glede na hrapavost povr{ine, napake notranjega premera in okroglosti pri trdem stru`enju notranjega roba izvrtine. Preizkusi trdega stru`enja so bili izvr{eni pri kaljenem in popu{~enem AISI 52100 obro~u le`aja z uporabo L9 ortogonalne matrike na CNC-stru`nici. Hitrost rezanja, hitrost podajanja in {tevilo obdelanih kosov so bili izbrani kot kontrolni faktorji. Optimalne razmere rezanja so bile izbrane z uporabo razmerja signal-hrup (S/N). S/N-razmerja so bila izra~unana s pribli`kom~im manj tem bolj{e. Analiza variance (ANOVA) je bila tudi uporabljena za dolo~itev vpliva kontrolnih faktorjev na hrapavost povr{ine, napak notranjega premera in okroglosti. Kon~no so bili optimalni parametri potrjeni s potrditvenimi preizkusi.
