What is the function of a contact method in manufacturing processes?

• Detecting physical or energy contact between a product and a sensing device

• Counting the number of parts attached to a product

• Detecting motion or steps within a certain period of time

• Counting the number of operations done at a workstation

Which device is commonly used in a physical contact method to detect contact with a part?

• Switches

• Photo-electric devices

• Limit switches

• Sensors

When is the fixed value method used in manufacturing processes?

• When a product makes physical contact with a sensing device

• When events need to happen in a certain sequence

• When a fixed number of parts must be attached to a product

• When a motion or step needs to be detected

What does the motion step method detect in a manufacturing process?

• Whether a motion or step has occurred within a certain period of time

• The number of operations done at a workstation

• The number of parts attached to a product

• Physical contact between a product and a sensing device

Which device is used in the fixed value method to detect when the required amount of holes are drilled?

• Limit switches

• Sensors

• Photo-electric devices

• Switches

What is the purpose of the sequencing aspect in the motion step method?

• To detect physical contact between a product and a sensing device

• To count the number of parts attached to a product

• To ensure events happen in a certain sequence

• To count the number of operations done at a workstation

Where are detective functions typically placed in manufacturing processes?

• At the end of the process

• Far from where mistakes occur

• Close to where mistakes occur

• Randomly throughout the process

What happens if a step in the process does not occur or occurs out of sequence in the motion step method?

• The sensor shuts down

• The process continues as normal

• The machine stops and signals the operator

• The product is released to the next process

What is the purpose of using a contact method in manufacturing processes?

• To count the number of operations done at a workstation

• To detect physical or energy contact between a product and a sensing device

• To ensure events happen in a certain sequence

• To count the number of parts attached to a product

When is the fixed value method not suitable for detecting manufacturing errors?

• When a fixed number of parts must be attached to a product

• When a product makes physical contact with a sensing device

• When events need to happen in a certain sequence

• When a motion or step needs to be detected
