Laser Cutting Machinery

can someone help me solve this supply/demand graph?

5. During the late 1990’s many consumers were having their vision problems corrected by laser surgery. An article in the Wall Street Journal in early 2001 noted two developments in the market for laser eye surgery. The first was about increasing concerns related to side effects from the surgery, including blurred vision and, occasionally, blindness. The second development was that the companies renting eye-surgery machinery to doctors had reduced their charges. One large company had cut its charge from $250 per patient to $100. Use a demand and supply graph of laser surgery to illustrate the effects of these two developments on the market for laser eye surgery. In what direction would equilibrium price and quantity change?

i know the first development would make demand shift left, but what about the second development?

Thanks for any help!

First, demand for eye surgery decreased due to medical concerns; thus, less demand for eye surgery. Then eye surgery costs decreased in an attempt to recapture market (increase consumer demand to meet supply of doctors doing surgery).
Supply of doctors doing surgery would decrease over time as consumer demand decreased. Thus, rental of machinery decreases. Rental rates decreased to generate demand for machines. BUT, overall there is:
- a continuing consumer demand decrease
- a continuing supply of doctors decrease
Lowering machinery rate of rental in a overall decreasing market will not increase machinery rental rates or customer demand or even the number of doctors simply because the consumer has determined that medical concerns still exist.
Price could equalize at what the market demands, but consumer demand will continue to decrease.

Different Ways of Cutting Sheet Metal

There are many different ways of cutting sheet metal. You can get the job done by using simple tin snips, large powered shears or bulky computer-operated machinery for more precise cutting.

Below are some of the most common methods to fabricate and cut sheet metal:

Laser Cutting

One of the latest methods of cutting sheet metal is laser cutting. In this operation, a specialized computer numerical control (CNC) laser is used to heat and burn the sheet metal, allowing a beam of laser light to pass through its surface. By permitting oxygen through the same nozzle from which the beam goes out, the sheet metal can be cut in a fast, smooth and precise manner.

Punching

Punching is another way of cutting sheet metal. This is carried out by moving the sheet of metal between the top and bottom tools of a punch machine. As compared to laser cutting, punching is less flexible in terms of cutting complicated shapes, but relatively faster in repetitive outlines. The grille of an air conditioning unit, for example, is usually made through punching.

Cutting Sheet Metal With Tin Snips

Sheet metal can also be fabricated and bent without using any machines. In fact, conventional hand tools such as a knife or axe along with a hammer will do the job. For hobbyists, cutting sheet metal with tin snips is a popular method, but a very tricky one. Sheet metal edges are sharp and the cutoffs are stiff, making it difficult to negotiate the curve. These dilemmas are common for those who don’t work with sheet metal on a regular basis. To successfully cut sheet metal using this traditional method, one must use the proper tools and know the necessary techniques.

You can choose from a wide array of tin snips in the market today, and selecting the right one can be a challenge. If you’re just a beginner, most experts recommend an offset compound tin snips. The cutters must be offset under the handle so you can maintain your cutting hand above the work. Because of the compound action, you’ll exert less time and effort even in cutting thicker material. Take note, however, that compound snips are color-coded and are not created similarly. A green snips, for instance, is created to cut clockwise curves. A red snips is for cutting counter-clockwise curves.

Cutting Sheet Metal With Aviation Snips

Aviation snips can also be used in cutting sheet metal. Such tools are very popular among sheet metal workers and people who work in construction projects. Using aviation snips is difficult and, to a certain extent, painful, because the worker is obliged to place his wrist in an awkward position in order to grasp the section to be cut. Aviation snips with the cutting edges offset from the handle, also known as upright snips, may help minimize this awkward posture.
