TOOLING U: Basic Measurement 101 PRACTICE

Match the following descriptions with their correct purpose in the inspection process in manufacturing.

• To ensure that a product's manufacturing timeline is optimized

• To ensure that a product uses the most advanced technology available

• To ensure that a product incorporates cutting-edge technological solutions

• To ensure that a product is produced as quickly as possible

• To ensure that a product adheres to quality and standard requirements

• To ensure that a product matches specifications and is defect-free

• To ensure that a product is produced with an emphasis on cost-efficiency

• To ensure that a product is created with the cheapest materials possible

What is tolerance in the context of manufacturing?

• The amount of time allowed for a part to be manufactured

• The amount of stress a part can withstand before breaking

• The amount a dimension can vary from the nominal measurement without becoming unacceptable

• The amount of weight a part can support

What is the difference between a go gage and a no-go gage?

• A go gage measures time, while a no-go gage measures weight

• A go gage has one side that fits into a correctly sized hole, while a no-go gage does not

• A go gage is used for variable inspection, while a no-go gage is used for attribute inspection

• A go gage is electronic, while a no-go gage is mechanical

What does variable inspection determine?

• The speed at which a part was manufactured

• The actual measurement of a dimension in specific units

• The durability of a part under stress

• The electrical resistance of a part

What is accuracy in the context of measuring instruments?

• The degree to which a measuring instrument can repeatedly provide the same measurement of a dimension over time.

• The difference between an instrument's measurement reading and the true dimension of the object being measured.

• The amount of variance between measurement readings.

• The ability to hit the exact same location on subsequent attempts.

What does precision describe in the context of measurement?

• The ability of an instrument to measure different dimensions accurately.

• The difference between an instrument's measurement reading and the true dimension of the object being measured.

• The degree to which a measuring instrument can repeatedly provide the same measurement of a dimension over time.

• The ability to hit the exact same location on subsequent attempts.

What is resolution in the context of measuring instruments?

• The smallest unit of measurement a device can display

• The smallest amount of force a device can register

• The ability to hit the exact same location repeatedly

• The increments in which a highly sensitive instrument can measure

What is the ten-to-one rule related to resolution?

• An instrument must be able to display measurements in increments of 0.1 in.

• An instrument must be able to display measurements in increments as small as 0.0001 in.

• An instrument must be able to display at least one tenth of the measured part's required tolerance

• An instrument must be able to display measurements in increments of 0.1 in. for highly sensitive instruments

Which instrument is mentioned as an example of one that requires high sensitivity?

• A scale measuring units of force or pressure

• A micrometer

• An instrument with high resolution

• A device measuring in increments of 0.1 in.

Which of the following describes the smallest unit of measurement an instrument can display?

• Accuracy

• Precision

• Resolution

• Tolerance
