Machining

Fig. 1.1 Schematic principle of Electro Chemical Machining (ECM) 1.2 Principle of ECM Electrochemical machining removes material from the work piece by electrochemical process. The working principle is anodic dissolution in which the work piece as anode and the tool as cathode. Both electrodes are immersed in the electrolyte and electrical applied to these electrodes. The electric conduction is achieved through the movements of ions between the anode and cathode through the electrolyte. The…

The assigned material for this week's article summary assignment is titled "Metal polishing: Do this, not that". The article is authored by CTD Mike, and was published on 06 Oct 11. The article appears on the cheaperthandirt.com website, and may be sourced at: http://blog.cheaperthandirt.com/metal-polishing-this/. The article begins with the assumption you have a task to perform that involves removing metal. Should I use the Dremel rotary tool? Stones? If you want to make sure you don't jack up…

This summer I completed an internship for Northwest Diversified Machining, they create aerospace parts. The shop is run by a Navy Veteran. My supervisor was a very old fashioned man who didn’t share my same view point on the company but he was willing to work with me to see what I was trying to accomplish. Together we worked side by side with mutual goals of improving the company. My supervisors goal was to have me come up with a more efficient way to know what parts are in, worked on, and out…

When I began my first metals machining class in 2014, I would have never had the notion that it would mean as much to me as it does today. I did not actually think that I would want to make it my life-long career. I was uncertain that machining was the right path for me until I began my internship at Council Tool Company. The internship swayed my opinion of assembly workers or even an average labor job. I soon come to the realization that a heated and air conditioned workplace was for me. My…

1. Introduction 1.1 Lubrication Friction is caused during machining operation at tool and chip interface. This produces the heat which affects the machining performance in terms of surface finish, dimensional accuracy, tool life and machining cost. To reduce the heat different techniques have been utilized. Earlier, during industrial revolution water was utilized as a coolant but it caused corrosion [1]. With the development of technology different cooling and lubrication techniques have come…

an even better correlation [9]. Fan et. al., [10] described a new method to micro machine brittle material called micro abrasive water jet machining. The most important parameter for abrasive water jet machining is the rate of material removal. Fan et.al., [10] created a predictive mathematical model for the material removal rate for micro channel machining using…

human beings. First robot was invented by George devol in 1954. Robots are controlled with the help of computers; the desired work is programmed with the alphanumerical language and prescribed to the robot. Applications of the robots mainly include machining, assembly operations, pick and place industrial components with accuracy and high precision. 1.2 Structure of SCARA Robot The base structure of SCARA…

The one thing that came to me easy was machining a hubless drum. At first i didn't even know what a drum was but when i did it came easy. when machining the drum you first have to assemble it right on the machine. Once it's assembled right and put the vibration belt on you can start the steps to machining it properly. First you put the cutting bits in the middle of the drum and make it where it's touching a little bit…

exclusively for this experiment by immersing the sample in the electrolyte for approximately 30 minutes and a circular notch of 0.2mm deep was made by electric discharge machining. Both the array coils were excited at a frequency of 15 kHz for a sample thickness of 1mm. On the right hand side is the corrosion damage of electric discharge machining notch by Ultrasonic phased…

for advancement In 2015, I was forced into a position to make a choice if my current employment was right for me or if going to school would open up more opportunities for me. I was working full time at a local Computerized Numerical Control (CNC) Machining company, making enough to get by, some work freedom and…
