pulsed leaser micro polishing seminar report and ppt

Abstract:

A fundamental study of pulsed laser micro polishing (PL P) was conducted as a method for reducing surface roughness of micro/meso-scale metallic parts. Although PL P was shown to be an effective process at these scales, the knowledge of the process physics lacked thoroughness. The goal of this work, therefore was to improve upon the existing knowledge of PL P, with focus on developing physics based models, understanding the effects of various process parameters and developing s ....etc

Chemical Mechanical Planarization (CMP) is an important process in semiconductor chip fabrication. In the CMP process, excess material is removed and the surface is planarized by the action of chemical and mechanical forces. Shallow Trench Isolation (STI) has become a key technology for device isolation in recent times. In this method, a shallow trench is made on the silicon wafer between active devices, silicon dioxide is deposited over the trench as well as the active area and the excess silicon dioxide is removed by CMP. The oxide remaining ....etc

piezoelectric shoe charger

Shoe Charger is a popular project for middle school, high school and college students, and also for hobbyists. This is my best try. I encountered lots of challenges throughout this science project. I added some of my failed experiments at the end of my written project.

At the beginning of the project, I was hoping to invent a shoe charger to charge a smart phone. After many failed tries, my new goal was changed to turn on the smallest ipod for 2 seconds. Nevertheless, it was a fun project and I learned a lot from ....etc

pulsed laser micro polishing seminar ppt

Abstract
The objective of this work is to predict the final roughness of metal surfaces that have undergone pulsed laser micro polishing. The motivation for pulsed laser micro polishing is to reduce the surface roughness of parts whose surface texture can approach the feature size. Being able to predict the magnitude of the polishing and frequency (wavelength) content of the surface will assist in the design of optimal processing parameters with minimal experiments. Laser pulses are used to create shall ....etc

I want to draw a data flow diagram for a shoe store.It's a small shop where only 2 to 3 employees are working.I want the context diagram, level 0, level 1, use case,class diagram,sequence diagram etc.So can anyone help me to do this accurately.The drawing must not be simple.It must be accurate and all the necessary things must be included in it.I mean the system must go into the deep. ....etc

In this publication laser micro polishing with an additional laser beam for pre-heating of the surface is investigated.The influence of the following process parameters on the surface roughness is examined: Pre-heating laser power, scanning velocity, beam offset of the two laser beams, and intensity distribution of the pre-heating laser beam. The two materials which were used for the experiments (martensitic tool steel and TiAl6V4) showed a different behavior: For martensitic tool steel the micro roughness was increased in comparison to convent ....etc

automatic shoe polishing machine ppt

Shoe polish (or boot polish), is a waxy paste, cream, or liquid used to polish, shine, and waterproof leather shoes or boots to extend the footwear's life, and restore, maintain and improve their appearance.Various substances have been used as shoe polish for hundreds of years, starting with natural substances such as wax and tallow. Modern polish formulas were introduced early in the 20th century and many of those original formulations are still in use today. Today, shoe polish is usually made from a mix o ....etc
