Automated Manufacturing Systems 1

Developed by: youngams_edu

Lets test what you have learnt!

Question 1: Analog to digital conversion is commonly used because:

	Many sensors are analog
	Few computers are digital
	Almost all sensors are digital
	This boost the signal

Question 2: The advantages of semi-automation, with both people and machines involved in the manufacturing process, are the:

	Use of the greater flexibility and ingenuity of people
	Reduced cost of expensive machines
	Maintenance times available

Question 3: A block diagram is sued to illustrate the:

	Relationships between system components
	Damping used in the system design
	Program in the microprocessor
	Cost of system components

Question 4: The name of the sensor used to measure applied pressure is:

	Solenoid
	Potentiometer
	Strain gauge
	Ventri tube

Question 5: The optimum system response to feedback is referred to as:

	Underdamped
	A discrete system
	Critically damped
	A continuous system

Question 6: An actuator commonly used to act as a type of switch would be a:

	Thermistor
	Stepper motor
	Solenoid
	Relay

Question 7: When discussing automated manufacturing systems, the term "noise" would refer to:

	A machine that is most likely faulty
	A loud machine
	Unwanted electrical signals
	High frequency electrical signals

Question 8: The three basic types of automated manufacturing systems are:

	Batch, continuous and discrete
	Batch, prototype and discrete
	Electronic, mechanical and pneumatic
	Manual, electronic and microprocessor

Question 9: The most suitable sensor for detecting a sudden change of motion is:

	A relay
	An accelerator
	A linear potentiometer
	A magnetic transducer

Question 10: Computer aided manufacturing is used so much these days because:

	Human workers cause a lot of problems with sickness and stoppages
	Data from the design stage can be integrated using the software
	This process is much less expensive to set up in the first place
	Machines never make mistakes like human workers do
