“…Each area of the form is made into the desired shape with one of the standard grinding wheels, and finally, using several grinding wheels creates the final shape of the form tool. The following method is profile grinding, which has the same profile as a single grinding wheel [9]. The difference is that special abrasive materials such as CBNs must be used for grinding cutting tools, which have very high mechanical strength.…”

In this research, a comparison between two methods of grinding and WEDM and the chip formation of each form tool was studied through a set of designs of experiments. A multi-functional form tool with different cutting-edge shapes was designed to compare different production methods, and a grinding machine and a five-axis wire-cutting machine were made. The form tools by the wire cutting method were made with three different machining states, rough, semi-finish, and finish. The results of the experimental test showed that the chip formation of the finished surface of the wire cut tool was close to the ground tools. Additionally, the tool life in wear generation was assessed, revealing that the tool generated through the wire-cutting method with three passes exhibited superior performance compared to alternative approaches. Furthermore, employing the wire-cutting technique with high surface finishing yielded optimal outcomes for producing form-cutting tools featuring complex profiles.

“…At the same time, the environment of off-position measurement is generally different from the machining environment, which may easily cause the measurement results to not accurately guide the compensation machining. The third method is to use the method of in situ measurement [ 2 , 3 , 4 ] and compensation machining [ 5 , 6 ] to improve the accuracy of the surface shape. This method not only reduces the requirements on the performance of the machine tool but also avoids the impact of the secondary clamping error and environmental changes.…”

The technology of in situ measurement of cylindrical shapes is an important means of improving the surface machining accuracy of cylindrical workpieces. As a method of cylindricity measurement, the principle of the three-point method has not been fully studied and applied, so it is seldom used in the field of high-precision cylindrical topography measurement. Since the three-point method has the advantages of a simpler measurement structure and smaller system error compared with other multi-point methods, the research on it is still of great significance. Based on the existing research results of the three-point method, this paper proposes the in situ measurement and reconstruction technology of the cylindrical shape of a high-precision mandrel by means of a three-point method. The principle of the technology is deduced in detail and an in situ measurement and reconstruction system is built to carry out the experiments. Experiment results are verified using a commercial roundness meter and the deviation of cylindricity measurement results is 10 nm, which is 2.56% of the measurement results of commercial roundness meters. This paper also discusses the advantages and application prospects of the proposed technology.

“…Many studies have investigated the grinding wheel's profile in-suit measurement. Xu et al [5] developed an in-suit measurement system consisting of a high resolution CCD camera, a telecentric lens and a parallel backlight. Li et al [6] proposed a novel grinding wheel profile measurement method based on an image mosaic algorithm, which is more efficient and accurate compared with the traditional ones.…”

In parallel grinding, the processing accuracy is directly related to the spherical grinding wheel shape accuracy. Therefore, it is very necessary to obtain the change information before ultra-precision grinding. This paper proposes an in-situ measurement scheme of spherical grinding wheel, including building an in-situ measurement system based on laser tool setter. The systematic error of this scheme is analyzed, the installation error model of laser tool setter is abstracted. Furthermore, the compensation of measurement data and high-precision in-situ measurement of spherical grinding wheel are realized. Finally, the error angle value is calculated by calibrating the 12.5mm standard ball for calibrating, and then 3mm radius standard balls are measured for verification. Experiments show that the measurement accuracy after compensation can be improved to 1.2µm.
