SACA 101 Study Guide questions with verified answers
Besides alarm screens and error messages, do you know what else an HMI is used
for? Ans✓✓✓-An operator can troubleshoot many problems directly from the
HMI panel.
can you calculate the power in a simple circuit? Ans✓✓✓-Power(W) = Current(A)
* voltage(V)
can you define continuity and state its importance? Ans✓✓✓-Electrical continuity
means there's a complete path for current to flow in a circuit.
Sometimes, a lack of continuity is desired, such as when a light switch is set to off.
However, if a wire or a component doesn't have continuity when it should, it
prevents current flow and circuit operation.
Can you describe how a CNC machine works? Ans✓✓✓-A CNC (Computer
numerical control) machine is a type of motion controller that can coordinate the
speed and positioning of multiple axes at the same time to cut complex features
into the metal part.
Can you describe the 8 deadly wastes? Ans✓✓✓-1. excess inventory
2. overproduction (more product than the next process or customer needs)
3. excess motion (movement by a team member that doesn't add value)
4. over processing (putting extra effort into a process that doesn't add value to
the customer)
5. transportation (any movement of the product within the facility)
6. waiting
,7. underutilized people
8. nonconforming product (any product that doesn't meet design specifications)
Can you differentiate value added and non value added activities? Ans✓✓✓-
Value-added activities transform or shape material and information that meets
customer requirements. example: cutting metal to make a part shape, or adding
paint to a product's surface.
Non-value-added activities take time resources or space, but do not add to the
value of the product or service. example: product inspection, or rework.
Can you explain line balancing? Ans✓✓✓-Line balancing spreads the workload
across workstations based on the speed of processing to avoid bottlenecks and
excess capacity. Line balancing allows the company to identify under-used and
overworked staff.
can you explain the operation of a 5-port, 3-position directional control valve?
Ans✓✓✓-When the spool is in the middle position, air flow is blocked between
all ports, this causes the cylinder to hold its position.
Pushing the operator handle causes the spool to shift, which makes the cylinder
extend.
Pulling the lever in the opposite direction causes the spool to shift to the third
position and reverse the port connections, which makes the cylinder retract.
can you explain the operation of a double-acting pneumatic cylinder? Ans✓✓✓-
when pressurized air enters the port on the cap end of the cylinder, it causes the
, piston and rod assembly to extend. air on the other side of the piston is pushed
out through the rod end port to atmosphere.
pressurized air entering the port on the rod end causes the piston and rod
assembly to retract. air on the other side of the piston is pushed out through the
cap end port to atmosphere.
can you explain the operation of MEMORY logic? Ans✓✓✓-Memory logic is used
to keep an output energized after the input signal that turned it on has been
removed.
Can you explain the operation of two types of transistors used in electronic
sensors? Ans✓✓✓-1. The PNP transistor provides a high signal at it's output
when the sensor is energized, or has detected the presence of an object.
2. the NPN transistor operates the opposite of the PNP transistor.
when the sensor is off, the voltage at the sensor's output terminal is high, the
sensor's output terminal is zero volts when the sensor is energized.
Can you give three examples of advanced manufacturing tools and techniques?
Ans✓✓✓-Industrial Robotics
Modeling and Simulation
Advanced Manufacturing
Can you identify 11 types of hazards in the workplace? Ans✓✓✓-1. Impact
2. Penetration
3. Compression
