 |  Quality Control Basics 42 Flashcards |  Start |
 | What is the purpose of quality control in manufacturing? |  Card: 1 / 42 |
| To ensure products meet specified requirements through inspection and monitoring. | Card: 2 / 42 |
| True or False: Common cause variation is due to identifiable sources. | Card: 3 / 42 |
| False. Common cause variation is inherent and random. | Card: 4 / 42 |
| Fill in the blank: Control limits are typically set at _____ standard deviations from the mean. | Card: 5 / 42 |
| ±3 | Card: 6 / 42 |
| What is the formula for calculating the sample mean (x̄)? | Card: 7 / 42 |
| X̄ = Σxᵢ / n | Card: 8 / 42 |
| What do X-bar charts monitor? | Card: 9 / 42 |
| They monitor the process mean over time. | Card: 10 / 42 |
| How is the process capability index Cp calculated? | Card: 11 / 42 |
| Cp = (USL - LSL) / (6σ) | Card: 12 / 42 |
| Multiple Choice: What does a Cpk value less than 1.33 indicate? | Card: 13 / 42 |
| C. Not capable | Card: 14 / 42 |
| What happens when a process is out of control? | Card: 15 / 42 |
| It shows points outside control limits or non-random patterns. | Card: 16 / 42 |
| What is the average range (R̄) used for in control charts? | Card: 17 / 42 |
| It is used to monitor process variability. | Card: 18 / 42 |
| Comparison: What is the difference between Cp and Cpk? | Card: 19 / 42 |
| Cp measures potential capability; Cpk considers process centering. | Card: 20 / 42 |
| What does a p-chart monitor? | Card: 21 / 42 |

| It monitors the proportion of defective items. | Card: 22 / 42 |
| True or False: A process is considered in control if all points are within control limits. | Card: 23 / 42 |
| True. | Card: 24 / 42 |
| What causes special cause variation? | Card: 25 / 42 |
| Identifiable sources not part of normal process operation. | Card: 26 / 42 |
| Scenario: If a new sample shows a mean outside control limits, what should be done? | Card: 27 / 42 |
| Investigate for special causes and take corrective action. | Card: 28 / 42 |
| Sequence: Put these steps in order: 1. Construct control chart, 2. Collect data, 3. Analyze results. | Card: 29 / 42 |
| 2, 1, 3 | Card: 30 / 42 |
| What is the purpose of acceptance sampling? | Card: 31 / 42 |
| To determine if a lot meets quality standards based on a sample. | Card: 32 / 42 |
| Riddle: I measure process stability and variability over time, what am I? | Card: 33 / 42 |
| Control chart | Card: 34 / 42 |
| How does one interpret a Cpk value of 1.00? | Card: 35 / 42 |
| The process is marginally capable and may need improvement. | Card: 36 / 42 |
| What is the relationship between Cp and Cpk? | Card: 37 / 42 |
| Cp can never be less than Cpk; Cpk accounts for centering. | Card: 38 / 42 |
| Multiple Choice: What does producer's risk (α) refer to? | Card: 39 / 42 |
| B. Rejecting a good lot | Card: 40 / 42 |
| What indicates an out-of-control process in a control chart? | Card: 41 / 42 |
| Points outside control limits or non-random patterns. | Card: 42 / 42 |
