Optical Flank Wear Monitoring of Cutting Tools
An optoelectronic method for in situ monitoring of the flank wear of cutting tools is presented. The method is based on real time vision technology in which the tool is illuminated by the beam of a laser and the wear zone is visualized using a Vidicon camera. The image is converted into digital pixel data and processed, to detect the wear land width. Detailed aspects of the image processing pro...
متن کاملFlank Wear Model of Cutting Tools Using Control Theory
A model of the flank wear of cutting tools is developed by using linear control theory. The flank wear is assumed to consist of a mechanically activated and a thermally activated component. The wear process is mathematically treated as a feedback process, whereby the progressive wear raises the cutting forces and temperature thereby increasing the thermally activated wear-rate, and contributes ...
متن کاملWear behavior of ZrAlN coated cutting tools during turning
In this study we explore the cutting performance of ZrAlN coatings. WC:Co cutting inserts coated by cathodic arc evaporated Zr1-xAlxN coatings with x between 0 and 0.83 were tested in a longitudinal turning operation. The progress of wear was studied by optical microscopy and the used inserts were studied by electron microscopy. The cutting performance was correlated to the coating composition ...
متن کاملMachine Vision System for Inspecting Flank Wear on Cutting Tools
This paper describes the development of a machine vision system for automated tool wear inspection. The proposed approach measures the tool wear region based on the active contour algorithm and classifies the wear type by means of neural networks. Test results show that prevalent tool wears can be checked robustly in a real production environment and therefore the manufacturing automation can b...
متن کاملAtomistic investigation of the wear of nanoscale diamond cutting tools shaped by focused ion beam
In recent years, micro/nanoscale diamond cutting tools shaped by focused ion beam (FIB) has been developed to the deterministic fabrication of micro/nano-structures owing to its unprecedented merits of high throughput, one-step, and highly flexible precision capabilities. However, the exposure of a diamond tool to FIB will result in the implantation of ion source material and the irradiation da...
