Smith is a Chartered Engineer and a Fellow of the Institutions of Mechanical and Electrical Engineers. Also covered are subjects important from a research perspective, such as micro-machining and artificial intelligence coupled to neural network tool condition monitoring.Ī practical handbook complete with troubleshooting tables for common problems, Cutting Tool Technology is an invaluable reference for researchers, manufacturers and users of cutting tools. The book covers new machining and tooling topics such as high-speed and hard-part machining, near-dry and dry-machining strategies, multi-functional tooling, ‘diamond-like’ and ‘atomically-modified’ coatings, plus many others. These wide-ranging manufactured components clearly show that there is a substantive machining requirement, which will continue to grow and thus be of prime importance for the foreseeable future.Ĭutting Tool Technology provides a comprehensive guide to the latest developments in the use of cutting tool technology. – rely to some extent on machining operations in their manufacturing process. It is a well acknowledged fact that virtually all of our modern-day components and assemblies – domestic, medical, industrial, automotive or aerospace, etc. This report includes a full development of the mathematical basis for the analysis and concludes with some application examples. The second modeling approach uses the techniques of principal component analysis to extract a basis set of characteristic shapes directly from the measurement data. One is an analytical model based on Chebyshev polynomials to model the axial errors and Fourier series to model angular dependencies. This work presents two useful models for form errors of cylindrical features and develops special cases of those models to suit specific requirements. In this report, a method is introduced that can identify key deviations from perfect form and can elucidate their dependence on some of the factors enumerated above. ![]() The problem is complex, involving the machine tool itself, materials, fixtures, cutters, feeds, speeds, and many other factors. To achieve this understanding, it is important to have high-quality metrology data on part features, which (in some sense) span the range of variability in form for the process under study. Increasing demands for precision-machined parts put a greater emphasis on achieving a better understanding of the relationships between manufacturing process variables and deviations from perfect geometric forms. These analyses indicated that the minimum tool measurement variations occurred when the spindle speed remained idle and the feed rate was kept at values typically around 0.25–9.5 mm/min. Statistical analyses were performed to identify the most adequate conditions based on the results of the experiments. For that purpose, two experimental procedures were conducted to obtain the values of tool diameter and length under diverse feed rate and spindle speed settings (a nominal Ø16 mm × 15 mm length referencing pin mounted into the tool holder was used). This paper discusses these influences and identifies the most adequate values for the feed rate and the spindle speed to reach an optimized measurement of the tools. However, the feed rate and the spindle speed used during referencing of the tool-setter (when the tool approaches the laser beam position) can influence the results of the measurements of a tool-setter due to the processing delay of the information by the CNC machine controls. One of these resources is the laser tool-setter, used to automatically measure the main dimensions (diameter and length) of the tools used in the machining process by means of the interruption of a laser beam located in a predetermined position. Sophisticated characteristics and resources have been implemented into these machines in order to achieve higher production rates and better dimensional quality. The use of CNC machines has been increasingly intensive in industry.
