Answer 1

True

Question 2

The three components of an automated system are which of the following:

A)actuators
B)communication system
C)control system
D)feedback loop
E)humans
F)power
G)program of instructions
H)sensors

Answer 2

control system
power
program of instructions

Question 3

A closed-loop system is a control system in which the output process variable of interest is compared with the corresponding input process parameter, and any difference between them is used to drive the output value into agreement with the input:

Answer 3

True

Question 4

An open-loop system is a control system in which the output process variable of interest is compared with the corresponding input process parameter, and any difference between them is used to drive the input value into agreement with the output:

Question 5

The three basic types of automated systems used in manufacturing are fixed automation, programmable automation, and flexible automation.Programmable automation is an extension of flexible automation in which there is virtually no lost production time for setup changes or reprogramming:

Question 6

The input/output relationship of a sensor is called which one of the following:

A)analog
B)converter
C)sensitivity
D)transfer function

Question 7

A stepper motor is which one of the following types of devices:

A)actuator
B)interface device
C)pulse counter
D)sensor

Question 8

A contact input interface is a device that reads analog data into the computer from an external source:

Question 9

A programmable logic controller (PLC) normally replaces which one of the following in control applications:

A)computer numerical control
B)distributed process control
C)humans
D)industrial robots
E)relay control panel

Question 10

Numerical control is a form of programmable automation in which the mechanical actions of a piece of equipment are controlled by a program containing coded alphanumeric data, the data representing relative positions between a work head and a work part:

Question 11

A numerical control system consists of three basic components: (1) part program, (2) machine control unit, and (3) processing equipment.The processing equipment is a microcomputer that stores and executes the program by converting each command into actions:

Question 12

The standard coordinate system for numerical control machine tools is based on which one of the following:

A)Cartesian coordinates
B)cylindrical coordinates
C)polar coordinates

Question 13

Identify which of the following applications are point-to-point and not continuous path operations (three correct answers):

A)arc welding
B)drilling
C)hole punching in sheet metal
D)milling
E)spot welding
F)turning

Question 14

The ability of a positioning system to return to a previously defined location is measured by which one of the following terms:

A)accuracy
B)control resolution
C)repeatability

Question 15

The APT command GORGT is which of the following (two best answers):

A)continuous path command
B)geometry statement involving a volume of revolution about a central axis
C)name of the humanoid in the last Star Wars movie
D)point-to-point command
E)tool path command in which the tool must go right in the next move

Question 16

The arm-and-body of a robot manipulator generally performs which one of the following functions in an application:

A)holds the end effector
B)orients the end effector within the work volume
C)positions the wrist within the work volume

Question 17

In robot programming, leadthrough programming involves a "teach-by-showing" method in which the manipulator is moved by the programmer through the sequence of positions in the work cycle, and the controller records each position in memory for subsequent playback:

Question 18

A SCARA robot is normally associated with which one of the following applications:

A)arc welding
B)assembly
C)inspection
D)machine loading and unloading
E)resistance welding

Question 19

In robotics, spray-painting applications are classified as which one of the following:

A)continuous path operation
B)point-to-point operation

Question 20

Which of the following are characteristics of work situations that tend to promote the substitution of a robot in place of a human worker (three best answers):

A)frequent job changeovers
B)hazardous work environment
C)repetitive work cycle
D)multiple work shifts
E)task requires mobility
