the price of single point diamond tools with a sharp tip is very high due to complex machining process and highly expensive machining equipments. yet, the performance is not quite satisfactory. in this paper, we have presented a very simple and cost effective machining process for the sharpening and polishing of diamond stylus using low energy reactive ion beam machining (ribm). in our method, ...

Electrical discharge machining process is one of the most Applicable methods in Non-traditional machining for Machining chip in Conduct electricity Piece that reaching to the Pieces that have good quality and high rate of machining chip is very important. Due to the rapid and widespread use of alloy DIN1.2080 in different industry such as Molding, lathe tools, reamer, broaching, cutting guillot...

By applying the etching via technology, this study proposes a novel front-side etching fabrication process for a silicon-based piezoresistive pressure sensor to replace the conventional back-side bulk micro-machining. This novel structure pressure sensor can achieve the distinguishing features of the chip size reduction and fabrication costs degradation. In order to investigate the sensor perfo...

The paper presents a concatenation of two methods for optimization of five-axis machining proposed earlier by the author. The first method is based on the grid generation techniques whereas the second method exploits the space filling curve technologies. Combination of the two techniques is superior with regard to the conventional methods and with regard to the case when the two methods are app...

Machining pieces with cylindrical symmetry are realized through classic processes for example turning, mortising, etc or recently through no conventional methods, for example vibrorolling and vibrofinishing. Solution adopted by the authors to realize vibrorolling equipment are composed of one electromagnetic vibrator with two coils out of time operating, static contactors with transistors for d...

Along with increasingly development of CAD/CAM software and their application in various industries, minimizing of the machining time is found to be more important. In this paper, firstly the concerning subjects are discussed regarding classification of the optimization techniques. These are programming techniques, high speed machining techniques and feed rate optimization techniques. As a case...

The dynamic MRR control is the goal to optimize machining operations in the CNC machining systems. The concentration on the minimum-cost machining control with material removal rate (MRR) grows up in the computer-based machining industry. In this paper, the mathematical modeling with dynamic MRR control to minimize the machining cost as well as schedule the due-dates for multiple machining proj...

The developments in the automotive industry are mainly motivated by the demand for more resource efficient vehicles. Besides this, there are high strength requirements for the used construction materials in order to implement efficient engines. As a consequence of the described requirements in the automotive field there exists a continuous trend towards the development of more resistant steels ...

Electrical discharge machining process, is one of the most widely used methods for machining, the electrically conductive parts. In this way the tool is not in contact with the workpiece and the hardness of workpiece does not affect the machining speed. In Electrical Discharge Machining process, selection of the correct machining parameters are effective in final cost and the quality of the pro...

Electrical Discharge Machining (EDM) process is one of the most widely used methods for machining. This method is used to form parts that conduct electricity. This method of machining has used for hard materials and therefore selects the correct values of parameters which are so effective on the quality machining of parts. Reaching to optimum condition of the DIN1.2080 alloy (D3) machining is v...
