Lab 1: Report Requirements (Due 20/2/2008):

A maximum of 5 pages, including the cover page, should include the following:

Critique of safety procedure in the workshop

A sketch of the lathe, the shaper, and the milling machine showing their main components and their functions in both English and Arabic.

Lab 2: FischerTechnick Components (the Lathe):

Report Requirements (Due 22/2/2008)

Introduce at least three modifications to the assembled lathe and indicate how they could be implemented.

Comment on team work during the lab. Specify how you divided the tasks within the team

Report is maximum 3 pages including cover page

Lab 3: Electrical Control Components II:

Report Requirements (Due 1 or 2/3/2008)

Use the attached symbols document and components presentation to:

Draw a circuit diagram of a conveyor belt system that will start when a photoconductive cell senses an object on the belt. The belt stops when the object hits a limit switch. The belt stays off even when the object is removed.
Design a circuit in which a bimetallic strip turns on an alarm light when heat increases. The alarm stays on until it is manually switched off.

Report is maximum 2 pages including cover page

One report for each group who performed the lab together

Lab 4: Electrical Control Components II:

Report Requirements (Due 15 and 16/3/2008)

Report is maximum 3 pages including cover page

One report for each group who performed the lab together

In the report, please:

Draw the circuit diagram of the conveyor belt system that you actually built and comment on any changes you made to the original design that you submitted on your Lab 3 report.
Modify your design to add a feature where an arm picks up the part when it reaches the end of the conveyor. The arm then rotates 180 degrees and stops when it is on top of a box where it drops the part. It is up to you to decide on the starting position of the arm. You will implement the system in Project 1.

Lab 5: Pneumatic Control Components II:

Report Requirements(Due 22 and 23/3/2008)

Modify the circuit diagram below to reflect the work of the press as developed in the lab.
Draw a pneumatic circuit diagram of weight control system that automatically pushes away under filled Pepsi bottles on the production line. Please build this system using Fischertechnik components and include a picture of your tested system in the report.

One report per group. Maximum three pages including the cover page

Piston Circuit

Lab 6: Pneumatic Control Components II:

Report Requirements (Due 29 and 30/3/2008)

Report is maximum4 pages including cover page

One report for each group who performed the lab together

In the report, please:

Document the circuits you assembled in the lab.
Design a pneumatic circuit where a single acting cylinder is activated when two valves are pressed simultaneously. Integrate this simple circuit with the one designed during the lab. (Hint: AND or OR gates can be used)
Design a pneumatic circuit that activates a timer (having preset value of 10 seconds) when one of two valves is pressed. Integrate this circuit with the one designed during the lab at a pressure of 4 bars. (Hint: AND or OR gates can be used)
