An NC Program merely guides and controls a Machining process. It cannot respond and react to variations in machining conditions during the operation. This results in many unfavorable situations like greater lead times, tool damage, extreme caution in work handling etc. during machining. In order to overcome above mentioned problems, the concept of ADAPTIVE CONTROL MACHINING was introduced. The purpose of introducing this concept is to control and optimize the variable cutting parameters. The applications of ACM are not only limited to NC machining but such systems are designed to...

Optical methods are increasingly used for measurement of surface texture, particularly for real measurements where the optical methods are generally faster. In the evaluation of surface roughness by machine vision technique, the scattered light pattern reflected from the machined surface is generally captured and optical surface finish parameters from the images are correlated with the actual roughness. Capturing of the image at appropriate conditions is required for the good correlation of the optical parameters with the roughness. Lighting conditions is a major factor that influences the...

In any machining process the economic objective is to maximize the metal removal rate by the highest possible feed rate under the constraint of tool breakage. An NC Program merely guides and controls a Machining process. It cannot respond and react to variations in machining conditions during the operation. Machining force regulation and tool wear are challenging problems since the force and temperature rise varies significantly under normal operating conditions. In order to overcome above mentioned problems, the concept of ADAPTIVE CONTROL MACHINING was introduced. Adaptive Control system...

Present work is an experimental investigation is presented for accomplishing surface texture analysis using machine vision based system for measuring the condition of cutting tool. Analysis of machined surface images of different materials by turning and shaping process at different wear conditions cutting tool, grabbed using CCD camera are presented. An amplitude parameters based approach for analysis of machined surfaces is proposed. Machined surfaces with different wear conditions of the cutting tool i.e., sharp, semidull and dull are investigated by using surface metrology software and...
