In my dreams, there is always a gun and a hand that pulls the trigger so that I startle with the sound of the shot and jump out of sleep and look for a subversion. It is as if you are lying in the shelter of darkness behind a thick curtain, when suddenly the curtain is torn from head to toe and white and furious light licks your naked body. I am sleepless again. I have to sit down and pour out everything that is in my mind and search around them until I find the gun and empty its magazine...

Surface roughness is one of the most important parameters that plays very critical role in determining the quality of engineering components. A good surface quality resulting in improve of fatigue strength, corrosion and wear resistance of the workpiece. On the other hand, increasing cutting speed and decreasing time of machining are desirable for manufacturers in order to reduce costs and increase rate of production. According to importance of above subjects, having high surface with low cost is required to have proper understanding of cutting parameters of WEDM. In this study, the effect of parameters such as Power, Time-off pulse, Open circuit voltage and Servo voltage on Tungsten carbide is investigated

The purpose of this paper is to examine the design method of a micro-constraint that, with proper performance, can automatically take a micro-part according to the important parameters of the reaction time and force, and after performing various steps on the part. Be. Release the piece and be ready to take the next piece. The use of CMOS technology in the design of retaining walls and the use of SMA technology in the design of the retaining bracket and its replacement instead of other existing designs in optimizing energy consumption power and reaction time, as well as combining the last two technologies play an essential role in this article. Is responsible. In the following, the mentioned design is examined through stimulation modeling based on mass and spring system and using mathematical software, analytical equations of stimulus movement based on time are extracted so that the time of deformation of stimulus can be calculated as a parameter.
