“…Non-contact measurement based on the principle of interferometry, optical sensors, optical microscopy, or three-dimensional imagining technology can realize a fast evaluation without any damage to workpiece surfaces [10,[12][13][14][15][16][17]. Nevertheless, most of them have high requirements on the measuring environment, such as temperature, vibration, and humidity [18,19]. Moreover, the tiny structure of a tool cutting edge makes optic-based non-contact measurement system not suitable for measurement of precision cutting tools [8,20].…”

This paper describes a comparison of the mechanical structures (a double-sided beam and a cantilever beam) of a probe in a tool edge profiler for the measurement of a micro-cutting tool. The tool edge profiler consists of a positioning unit having a pair of one-axis DC servo motor stages and a probe unit having a laser displacement sensor and a probe composed of a stylus and a mechanical beam; on-machine measurement of a tool cutting edge can be conducted with a low contact force through measuring the deformation of the probe by the laser displacement sensor while monitoring the tool position. Meanwhile, the mechanical structure of the probe could affect the performance of measurement of the edge profile of a precision cutting tool. In this paper, the measurement principle of the tool edge profile is firstly introduced; after that, slopes and a top-flat of a cutting tool sample are measured by using a cantilever-type probe and a double-sided beam-type probe, respectively. The measurement performances of the two probes are compared through experiments and theoretical measurement uncertainty analysis.

In the fields of energy, power engineering, defense, aeronautics and astronautics, the requirement for high-end equipment is vital, and the performance tolerances are extremely tight. In this environment, many high performance parts with considerable manufacturing complexity are created, which are often large in size, complex in shape and difficult to produce. The integrated technology of measuring and machining provides an effective route for high-quality and high-efficiency machining of these types of parts. In this paper, the basic implications and application directions of this integrated technology are introduced. Related research progress in measurement, data processing, theoretical modeling and key processes is reviewed with a focus on the machining localization, inverse modification of machining parameters, and the corrective machining of complex surfaces and surface-redesigned parts. Finally, the potential fields of application, key questions and development directions of the integrated technology are outlined. integration of measurement and machining, surface redesign, high performance, complex surface, error compensation

The continuing evolution of ultraprecision machining places an increasing need to perform surface measurement in the manufacturing environment. Development of on-machine surface measurement (OMSM) tools for ultraprecision machining processes will enable the reduction of measurement cycle time as well as the potential improvement of machining accuracy. In the present study, an in-house designed interferometer probe is integrated onto an ultraprecision diamond turning machine. System configuration, calibration scheme and various scanning strategies are first presented. The benefit of OMSM preserves the consistency between the machining and measurement coordinate system. Two applications of OMSM for ultraprecision turning process are further investigated. To further improve the surface accuracy, corrective machining is carried out based on the on-machine measured data. The profile accuracy of a cosine curve sample was improved after corrective machining with OMSM. Moreover, process investigation with OMSM was employed to model the effect of process parameters on the form error in ultraprecision cylindrical turning process. OMSM enables the consistent measurement of part coordinates for each experimental run, which is critical for acquiring a deterministic response for empirical modeling. A reduced quadratic model was built by means of response surface methodology and verified by the test for significance of the regression model. The confirmation tests show that the model predicted value conformed to the experimental value with a difference less than 4%.
