include taking 10 microns from steel plate

or 1.5 inches of bad concrete from a road

surface.

Stone Cutting is not just Stonehenge or

the Millennium Arch but Titanium and very small parts

63

Class projectA work of art will be designed and cut, in thick and thin material. The grade will be on the quality of the art.

64

From the class of 2005

65

Class Schedule

It is intended to hold the class twice a week for lectures and on occasion to hold a laboratory.

This will count as the first lecture, and will cover the schedule, the choice of meeting time, and where the labs will be held.

Lectures will use PowerPoint where possible and include some short segments of video from earlier work.

The class is covered by blackboard software - with which you should be familiar. (http://blackboard.umr.edu/

66

Class Schedule

August: Introduction, Safety and Pumps

September: Nozzles, hoses, 5-axis systems, cleaning surfaces,

initial cutting review.

October: Cutting with abrasive, milling and cavitation.

November: Abrasive slurry cutting, jet assisted cutting, geotechnical use,

December: Theoretical analysis and Medical applications.

67

Laboratory Schedules

A number of demonstration labs will take place.

Reports are due two weeks after the laboratory is held. They should be concise, comprehensive and explain: What equipment was usedWhat was done with itWhy the experiment was carried outWhat the results wereWhat the results indicate and any recommendations.

The major lab is to design and cut an object of your own design, in a thin and thick material. The grade will be based on the artistic merit of the piece. We keep one, you keep the other.

68

Books and Lecture Notes

Although the course will roughly follow the book “Waterjetting Technology” that text may not be easily available, although possibly may be obtained through the Bookstore. Sections of relevance will also therefore be posted on Blackboard.

Some papers and other material exist already on the Web and may be accessed. Electronic copies of others may be obtained upon request. You are expected to read material beyond just that handed out in class.

The class notes will, it is anticipated, be made up from the PowerPoint slides.

69

Web Resources

There are a significant number of places that provide useful information on the Web. Where time permits these will be referred to in the lecture slides, however it is useful to make up your own contact lists.

There are two organizations that you should be aware of

The Waterjet Technology Association (WJTA) - see

http://www.wjta.org. (students can join for $20)

And the International Water Jet Technology Association
