In turning process, engineers are often faced with the problems of relating the cutting parameters (Speed, feed, depth of cut) to the output responses(Feed force, Thrust force, Cutting force, Surface roughness) to optimize the process. Also, Turing is done with the aim of achieving the best surface finish. But without optimization, it is not possible to automate the process. Turning process inv...

The wear of cutting tool degrades the quality of the product in the manufacturing processes. The on line monitoring of the cutting tool wear level is very necessary to prevent the deterioration of the quality of machining. Unfortunately there is not a direct manner to measure the cutting tool wear on line. Consequently we must adopt an indirect method where wear will be estimated from the measu...

An analytical finite element technique was developed for predicting the thrust force and torque in drilling with twist drills. The approach was based on representing the cutting forces along the cutting lips as a series of oblique sections. Similarly, cutting in the chisel region was treated as orthogonal cutting with different cutting speeds depending on the radial location. For each section, ...

The condition of a cutting tool is an important factor in manufacturing processes. Tool wear has a strong influence on the cutting forces, resulting in a poor surface finish and impacting on the dimensional tolerance of the workpiece. Therefore, the use of a dynamometer during machining to measure cutting forces is a well-known approach but it has several limitations such as high cost, poor per...

ABSTRACT In this paper, the phenomenon of chatter vibration in metal cutting is investigated. For this purpose, a theoretical one-degree of freedom model of the vibrations generated in an orthogonal cutting process is developed. The dynamic cutting forces are strongly affected by the variations of the cutting process parameters, and the model is based on the mechanical theoretical prediction of...
