The wear behavior of cutting tools directly affects the quality of the machined part. The measurement and evaluation of wear is a time consuming process and is subjective. Therefore, an image-based wear measurement that can be computed automatically based on given image series of cutting tools and an objective way to review the resulting wear is presented in this paper. The presented method fol...

This paper presents a novel control architecture system which is composed of a multi-objective cost function which Pareto optimises the programming of cutting parameters while adapting the milling process to new cutting conditions if new constraints appear. The paper combines a self-optimised module which looks for and finds Pareto optimal cutting parameters according to multi-objective purpose...

Based on the cutting force theory, the cutting stress in end milling operation was predicted satisfactorily through simulation of using finite element method. The mechanistic force models were introduced in high accuracy force predictions for most applications. The material properties in the simulations were defined based on the cutting force theory, as a function of strain and strain rate wher...

This paper discusses the selection of tools in milling processes. To carry out this research, it has been developed an expert system based on numerical methods. The expert system, chooses an appropriate tool, between a known set of candidate available cutters. The knowledge base is given by limiting the process variables. They are obtained taking into account, instabilities due to tool-work-pie...

This paper presents the design and development of a real-time monitoring and diagnosis system for diagnosing degraded cutting regimes in Wire Electrical Discharge Machining (WEDM). The detection in advance of the degradation of the cutting process is crucial since this can lead to the breakage of the cutting tool (the wire), reducing the process productivity and the required accuracy. This work...

According to the disadvantages of former shearer cutting load measuring method and its low antiinterference ability, this paper proposes a new shearer cutting load measuring method based on the current spectrum. On the basis of load analysis of shearer cutting unit drive system, the theoretical models are established between cutting load and cutting motor current. Simulated load test to the ele...

This research explores the automated process adjustments of chip cutting operations by using neural network and statistical approaches in a computer-aided vision system. Multilayer ceramic capacitors (MLCC), owing to their excellent electronic characteristics, are applied in the design of high-density PC boards. The excellences of MLCCs are accomplished through rigorous controlling of every pro...

The manufacturing industries dealing with machining and tools' manufacturing generate a large amount of data concerning the machining process. However, in most cases, this information is not used in an advantageous strategy as there is no system dedicated for storing and manipulating such data. In order to Use these data to improve efficiency and increase benefit of machining, the cutting datab...
