ME 686: Micro-manufacturing Assignment 1 Study the effects of process parameters (speed‚ feed‚ depth of cut etc.) associated with SPDT for manufacturing of micro lens let arrays. Also find out the ranges of these process parameters and values of optimal process parameters. Submitted by: Marmeek Kishor Kumar Kosambia (09010332) Submitted to : Dr. S.N. Joshi Date of Submission: 17/01/13 Introduction A microlens array is composed of a series of micro lens distributed in a regular pattern

Paper Pros Paper decomposes more easily than plastic Paper is recycled more frequently than plastic Cons 14 million trees are cut down yearly for the manufacturing of paper. Thousands of gallons of fresh water and bleach are used to clean the pulp in the production of paper bags Paper produces 70% more air pollution and 50 times more water pollutants than plastic bag production. It takes 4 times as much energy to manufacture a paper bag as it does to manufacture a plastic bag.

Parachute Investigation Lab Report Hypothesis: I predict that as the surface area of the canopy increases‚ the time it takes for the parachute to fall also increases. This is because the air resistance is larger‚ therefore the drag is increased. So the speed of the parachute decreases. This is because the forces (air resistance and gravity) are unbalanced. The change in air resistance is important because the larger the surface area of the canopy‚ the more air particles it

Mahindra Verito (Mfg) The Mahindra Verito‚ formerly known as Logan is Mahindra’s flagship car in the sedan entry level segment (C- seg). The car is manufactured at the Chakkan plant in Maharashtra. Plans are being made to shift out to a new plant coming up in Chayyar‚ about 100 Km from Chennai. The average monthly sales of Verito is about 1250/month ever since the rebranding. It is a bit less than forecasted by M&M. Daily production is about 70 cars per day. Not a lot of considerable changes

1.) the diagonal of a rectangle is 25 meters long and makes an angle of 36 degree with one side of the rectangle. Find the area and the perimeter of the rectangle. 2.) A side of a square is 16 inches. The midpoints of its sides are joined to form an inscribed square. Another is drawn in such a way that its vertices would lie also at the midpoints of the sides of the second square. This process is continued infinitely. Find the sum of the areas of these infinite squares. 3.) A rectangle and a

Aim: To determine the relationship between the length of eureka wire‚ and resistivity of the wire. Hypothesis: As the length of the wire increases‚ the resistance of the wire will increase. Background: Some materials have consistent resistance at the same temperature regardless of how much voltage is applied through them‚ these materials are known as ‘Ohmic’ resistors. This is because they are said to obey Ohm’s law‚ which states that if a voltmetre is used to measure the voltage (V) of

Diatomite ，also known as diatomaceous earth ‚ is a naturally occurring soft . It is easily crumbled into a fine white to off-white powder. It has a particle size ranging from less than 3 micrometers to more than 1 millimeter‚ but typically 10 to 200 micrometers. Depending on the granularity‚ this powder can have an abrasive feel. It is very light because of its high porosity. Diatomite consists of fossilized remains of diatoms. It is used as a filtration aid‚ mild abrasive in products including toothpaste
