Minimum quantity lubrication (MQL) based machining methods are widely used in industry now-a days as they environment friendly and save cutting fluid costs. In the present work to augment the advantages of MQL in turning, a bi-objective optimization of process parameters in MQL turning is presented. The optimum selection of process parameters in turning has a significant role to ensure quality ...

Studying how metal deforms and flows as parts are machined yield important insights into the metal cutting process. Improvements in high-speed digital imaging and image processing software promise to improve our understanding of the tool-workpiece interface and verify the accuracy of finite element modeling simulations. This will ultimately enable industry to improve machining processes and mak...

Electrical discharge machining is assessed on the basis of Material Removal Rate (MRR), Tool Wear Rate (TWR), and Surface Roughness (SR). Process parameters that mostly affected the EDM Process are Pulse on Time, Pulse off Time, Discharge Current, Arc Gap and Duty Cycle. This paper reviews research for the optimization and improvement of various performance parameters measured in the experiment...

Typically, NC programmers generate tool paths for end milling using a computer-aided process planner but manually schedule “conservative” cutting conditions. In this paper, a new evolutionary computation technique, particle swarm optimization (PSO), is proposed and implemented to efficiently and robustly optimize multiple machining parameters simultaneously for the case of milling. An artificia...

Commercial and industrial pick and place systems are now in widespread use performing jobs more cheaply or with greater accuracy and reliability than humans. They are also employed for jobs which are too dirty, dangerous or dull to be suitable for humans. Pick and Place Systems are widely used in manufacturing, assembly and packing, transport, earth and space exploration, surgery, weaponry, lab...

In the last years new methods have been investigated for the manufacturing of artificial implants for hip joints. For some parts of these implants, like femoral heads, the method of high speed machining is used to get manufactured. In this paper it was investigated the connection between cutting parameters and forces, in high speed turning of metallic femoral heads. This method is widely used i...

After Gough [1] and Stewart [2] in the 50's and 60's introducing the idea of ‘hexapods’ (6-dof) [3][4], Clavel and his Delta structure [5] in the late 80's opened a new era with machines able to reach extremely high performances, used first for pick-and-place operations, and more recently for 3 or 5-axis machining. Considering the machining of complex shape objects, the solution often proposed ...

It is a very challenging task to develop effective process control methodologies for multi-operational manufacturing processes. Although Statistical Process Control (SPC) has been widely used as the primary method in the control of quality, it mainly serves as a change detection tool rather than a method to identify root causes of process changes. This paper proposes a systematic approach to ov...

This paper presents an introductory review of CBM practice applied in manufacturing industry, focusing the technical constituents within condition monitoring. The empirical base for the study is a case study of two major manufacturing sites in Sweden, complemented with a brief benchmark of data from two reference manufacturing sites from France and Brazil. The data from the main studies were co...

A New Geometric-and-Physics Model of Milling and An Effective Approach to Medial Axis Transforms of Free-form Pockets for High Performance Machining Qiang Fu, Ph.D. Concordia University, 2010 Mechanical part quality and productivity depend on many parameters in CNC milling processes, such as workpiece material, cutters, tool paths, feed rate, and spindle speed, etc. To pursue high performance m...
