7 Steps To Set Up Statistical Process Control (SPC) On Production Processes

  1. Select critical-to-quality (CTQ) product characteristics. ...
  2. Select critical processes. ...
  3. Determine if machines can calculate SPC by themselves. ...
  4. Gather data and process knowledge of what impacts the output of the process.

What is statistical process control methods?

Statistical Process Control (SPC) is an industry-standard methodology for measuring and controlling quality during the manufacturing process. Quality data in the form of Product or Process measurements are obtained in real-time during manufacturing.

How do you implement SPC?

The SPC implementation

  1. Step 1: obtain management support. ...
  2. Step 2: choose an SPC leader. ...
  3. Step 3: select a pilot study production process. ...
  4. Step 4: prepare production assembly procedures. ...
  5. Step 5: provide SPC training. ...
  6. Step 6: construct control charts.

How do you determine statistical control?

Control charts are used to determine whether a process is in statistical control or not. If there are no points beyond the control limits, no trends up, down, above, or below the centerline, and no patterns, the process is said to be in statistical control.

What is an SPC chart?

The main type of chart is known as a Statistical Process Control (SPC) chart and plots your data like a run chart every week so you can see whether you are improving, if the situation is deteriorating, whether your system is likely to be capable to meet the standard, and also whether the process is reliable or variable ...

What are the five steps of statistics?

The Statistical Process has five steps: Design the study, Collect the data, Describe the data, Make inferences, Take action. In a designed experiment, researchers control the conditions of the study.

How to implement the statistical process control tutorial?

The first implementation step of the statistical process control tutorial is to define the methods for measurement purposes. As SPC is founded on the data analysis, so it must be decided at that initial stages that what data must be collected. Variable or Attribute is the two types of control chart differentiated by the type of data used.

What's the difference between SQC and statistical process control?

Statistical process control is often used interchangeably with statistical quality control (SQC). A popular SPC tool is the control chart, originally developed by Walter Shewhart in the early 1920s.

How does statistical process control ( SPC ) in China?

While SPC can help control processes and ensure consistent output, many of China’s factories seldom apply it. To understand how this tool works, it is best to follow the logical steps in its implementation in a factory:

How are SPC tools used in process control?

SPC tools and procedures can help you monitor process behavior, discover issues in internal systems, and find solutions for production issues. Statistical process control is often used interchangeably with statistical quality control (SQC).
