1. Many production lines are automated. What is an automated production line?

 
 
 
   

2. An automated production line is shown below. Parts / components move along the production line where they are sensed, clamped down, drilled and then released, moving down the production line again.

   
   

The whole process is controlled by a PIC Microcontroller. The conveyor belts rotates continually until the sensor detects a component.

   

Write the sequence of instructions for the entire process on the following instruction sheet. Basic instructions you are to use are described below.

   
     
You are to write your answer as a set of instructions and as a flowchart.

4. Each component being drilled is identical. Each has a central hole and is rectangular in shape. It has been decided that each component must be checked for the presence of the hole after drilling. This is part of quality control.

   
4a. What is the meaning of quality control?
 
 
   

4b. Using sketches and notes explain how the circuit shown at the top of the page could be used to check for the presence of the hole in each component.
