Regulating machining forces provides significant economic benefits by increasing operation productivity and improving part quality. Machining force regulation is a challenging problem since the force process varies significantly under normal operating conditions. Since fixed-gain controllers cannot guarantee system performance and stability as the force process varies, a substantial research ef...

The manufacturing technology of milling, drilling and turning tools have demands of new developing markets as well as quality and lifetime aspects of the machining. In order to achieve the high precision required by machining, the structure and form of the cutting edge of the tools must be investigated to provide the most influential properties. Correlation between the tool wear on the cutting ...

In this paper a methodology based on multi-objective particle swarm optimization algorithm, for identifying the optimal parameters for machining a workpiece with a milling is presented. The time for machining, the material removal rate, and the feed rate were identified as the objectives to optimize. In addition, the proposal considered 4 constraints related to cutting tools, rotating speed of ...

A unique micro electrochemical machining (ECM) method based on a scanning micro electrochemical flow cell (SMEFC), in which the electrolyte is confined beneath the tool electrode instead of spreading on the workpiece surface, has been developed and its feasibility for fabricating mesoscale channels has been investigated. The effects of the surface conditions, the applied current, the feed rate,...

In order to study the influence of spindle speed and amplitude on surface integrity, TC18 titanium alloy samples were milled by process conventional milling longitudinal ultrasonic vibration assisted milling. The experimental data obtained dynamometer, thermometer, scanning electron microscope, X-ray diffractometer, three-dimensional topography instrument for observation analysis. results show ...

We investigate a recently introduced methodology for 5-axis flank computer numerically controlled (CNC) machining, called double-flank milling (Bo et al., 2020). show that screw rotors are well suited this manufacturing approach where the tool possesses tangential contact with material block on two sides, yielding more efficient variant of traditional milling. While tool’s motion is determined ...

Thin-walled aluminium parts are employed in a variety of industries, including construction and aerospace. If they treated to greater quantity milling, more resistant deformation. As result, the stability work degrades, surface roughness increases as result this factor. This proposes use well-designed fixture with support heads lessen deformation produced by square thin-walled plate milling. Th...

The present work analyses different parameters of end milling to minimize the surface roughness for AISI D2 steel. D2 Steel is generally used for stamping or forming dies, punches, forming rolls, knives, slitters, shear blades, tools, scrap choppers, tyre shredders etc. Surface roughness is one of the main indices that determines the quality of machined products and is influenced by various cut...

In die manufacturing industries surface roughness is considered as a vital quality characteristic in order to retain the consumers’ satisfaction. On the other hand, manufacturers want to minimize the machining time which eventually reduces their cost. This research deals with an optimization problem to minimize the machining time (T) for end milling operation on hot die steel (H13), subject to ...
