Nowadays, carbon fiber reinforced plastics (CFRP) composites is widely used in the aerospace industry due to its excellent mechanical properties. In laser cutting process, high powers are used to cut materials then material melts and burns leaving edges with a high quality finish. To fulfill the high demand of cutting quality, a set of laser cutting parameters of CFRP material are studied. The ...

Optimum selection of cutting conditions importantly contribute to the increase of productivity by minimization of production time and the associated costs, therefore utmost attention is paid to this problem in this contribution. Time is the most important parameter in any operation and all the manufacturing firms aim at producing a product in minimum time to reach the customer quickly and enhan...

Packet classification is one of the fundamental techniques required by various network management functionalities. As the state-of-the-art of software packet classification, decision-tree algorithms employ various geometrical cutting schemes to build optimized decision trees. However, existing cutting schemes cannot meet the desired performance on large rulesets because they sacrifice either cl...

This research work focusses on optimization of machining and geometrical parameters during turning AISI 1045 steel using carbide cutting tool insert, by Finite Element Analysis and Taguchi’s Technique. Three levels of cutting speed, feed rate, depth of cut, cutting insert shape, relief angle and nose radius are chosen. A suitable L18 Orthogonal array is selected based on Taguchi’s Design of Exp...

This study successfully applied multi-mode laser cutting with the variation of the laser cutting speed to cement mortar for the first time. The effects of the amount of silica sand in the cement mortar on laser cutting are tested and analyzed. The kerf width and penetration depth of the specimens after laser cutting are investigated. As the laser cutting speed increases, the penetration depth d...

Industrial high-speed laser operations the use of delta parallel robots potentially offers many benefits, due to their structural stiffness and limited moving masses. This paper deals with a particular Delta, developed for high-speed laser cutting. Parallel delta robot has numerous advantages in comparison with serial robots: Higher stiffness, and connected with that a lower mass of links, the ...

Bio -material cutting, such as meat deboning, is one of the most common operations in the food processing industry. It is also the largest employer of people in the United States. These tasks are currently manual processes with only limited use of fixed automation. The main difficulty in this task is the natural variability of the product's size and individual anatomy. The industry is looking t...

Metal matrix composites (MMCs) attract considerable attention as a result from its ability in providing a high strength, high modulus, high toughness, high impact properties, improving wear resistance and providing good corrosion resistance compared to unreinforced alloy. Aluminium Silicon (Al/Si) alloy MMC has been widely used in various industrial sectors such as in transportation, domestic e...

the drilling is well known as one of the most common hole making processes in the industry.due to close tolerance requirement for drilled holes in the most of work pieces, onlinecontrolling of the diameter of drilled holes seems to be necessary. in the current work, an onlinedimensional controlling system was developed for drilling process. doing this, drilling processwas executed in different ...
