This paper discusses the preliminary development of a neural network based process monitor and off-line controller for abrasive flow machining of automotive engine intake manifolds. The process is only observable indirectly, yet the time at which machining achieves the specified air flow rate must be estimated accurately. A neural network model is used to estimate when the process has achieved ...

The main objectives of multi-axis machining are to achieve perfect surface quality, precision, and speed without any need for re-machining. Within cutting processes, a strong integration of technologies such as virtual machining and inspection algorithms is important [1]. Closed Loop Machining (CLM) is an important method to maximise the efficiency of cutting processes, and automatic data colle...

Presented is an experimental investigation of the machining characteristics and the effect of wire electrical discharge machine (WEDM) process parameters during machining of Al/ZrO2(p) particulate reinforced metal matrix composite (PRMMC). Experiments are carried out to investigate the effects of input parameters such as dielectric conductivity, pulse width, time between pulses, maximum feed ra...

This paper presents a functional microstructured surface, named Polar Microstructure. Polar microstructure is a three dimensional (3D) structured surface possessing a pattern of distribution of latitude and longitude micro-topographies with geometrical characteristics, which is similar to that in the Earth’s north or south pole. The spacing of its small surface features can achieve form accurac...

This paper deals with the study of various machining process and show the effect of different cutting parameters on the properties of material. There are several important factors in the product quality which are surface finish, cutting temperature, tool life and coolant quality. The use of coolant generally causes life of tools and it also maintains work piece surface properties without damage...

This paper discusses a practical example of machining crank shafts, which are the central part of compressors made in mass production, in order to point out the importance of selecting proper machining parameters and presenting their further relation to product quality. As the shaft’s dimensions varied significantly after machining in comparison to the prescribed one, an analysis of the relatio...

The paper is focused on the theoretical and practical application aspects concerning the approach methods to CNC simulation using the CATIA program, Machining module. The authors propose some variants of optimization, such as: the type of the cutting tool used, path and division pattern of the stock left for machining, parameters of cutting regimes, efficient use of machine-tools (rotative spee...
