Statistical Process Control (SPC) is a way of controlling production or processes with the help of certain statistical techniques. With the right statistical control process, you’ll be able to effectively monitor all process activity, proactively identify and address any internal issues, and determine the best methods for fixing them at any point during production.
G.E. Mathis Company implements rigorous SPC tools and procedures to optimize our products and services. We serve companies across a variety of industries, with capabilities like precision laser cutting, plasma cutting, CNC punching, welding, and other custom OEM solutions.
Statistical Process Control
In most cases, statistical process control relies on certain types of control charts, such as the IX-MR and X bar R charts. These charts are prepared in advance for machine operators, who would take measurements of a product characteristic and make measurement entries on the control chart. Using simple math, they plot points and draw lines from one point to the next. In the process, operators would be able to notice any potential issues based on the patterns present, including trends, freaks, and shifts in data.
Once they recognize these patterns, operators can then take the necessary steps to correct any out-of-control conditions present. As a result, processes benefit from improved performance, leading to high-quality output and reduced waste and rejections. The SPC procedure translates to customer satisfaction.
Statistical Process Control Tools
The following statistical tools are the most common ones used in business today:
- Pareto Charts
- Trend Charts
- Statistical Process Control (SPC)
- Histograms
- Cause-and-Effect Diagrams
- Structure Trees
- Scatter Plots/Diagrams
- Pie Charts
- Spider Charts
- Flow Charts
- Gantt Charts
- Stacked Area or Bar Charts
Statistical Process Control Benefits
SPC offers numerous advantages that make these solutions worth implementing.
Reduced Defects, Waste, and Rework
One of the main benefits of SPC is the development of streamlined processes that make it easier for operators to identify issues and correct them before they can develop into bigger problems. The end result is significantly reduced waste, a lower risk of defects, and the eliminated need for reworks.
Enhanced Product Quality
Another benefit of statistical process control is better product quality, as the SPC tools you use can help spot any problems during production. You can then begin correcting these issues, creating a continuous process that optimizes product quality while preventing shutdowns and downtime.
Elimination of Process Variation
The software and charts you use for the statistical control process will help you determine if there are any process variations to address. You’ll have access to comprehensible data in a graphical format that makes it easy to identify irregular patterns, enabling you to correct them and improve the process.
Compliance With Customer and Regulatory Requirements
SPC software also facilitates compliance with both industry regulations and customer requirements. Businesses can then maintain their operations without concerns over regulatory violations while providing customers with high-quality products that keep them happy.
Reduced, Controlled Expenses
Statistical process control tools help identify and mitigate imperfections in products and processes, helping to minimize the costs associated with rework.
