Improving Quality with
Without Real Quality Measurements, Scrap is Just Money Going Down The Drain.
Production quality product is core to what manufacturers do. Producing a product with quality issues will result in additional costs, rework and possibly unhappy customers. Most customers rate their suppliers on a number of different quality metrics and will only award contracts to those who consistently deliver a product that meets their specifications.
OEE: Improve Quality
We talk a lot about Overall Equipment Effectiveness, the benefits of measuring OEE and using it in process improvement projects. As you know OEE is made up of 3 basic components
Correctly calculating quality is essential to a reliable, realistic OEE. Quality measures the amount of good parts produced vs total parts produced. To calculate Quality of a part, SensrTrx collects part counts and reject reason codes directly from the PLCs or other sensors. SensrTrx can also augment this information with input from operators or supervisors.
This includes data taken from specialized testing equipment and data beyond reason codes such as temperature, pressure, speeds, vision systems and any other data points accessible from the equipment.
Pareto Charts for Manufacturing Quality
SensrTrx offers Pareto Charts out of the box to help determine the most common causes of scrap. SensrTrx Pareto charts come from Vilfredo Pareto who identified the 80/20 rule and created the chart that bears his name.
In this Pareto chart the number of rejected parts is grouped by reason code. In the detailed view, 80% of our scrap is caused by 2 reasons:
- Tool Break
Scrap Details by Reason
You can also see the trend of each reason code, are we producing more scrap or less over time.
Scrap by Shift
You can also look at scrap by shift and reason code to determine if one shift has more scrap than another. Scrap can be analyzed by shift. In this case, 3rd shift has more rejected parts that 2nd or 1st. There may be a training opportunity to improve quality.
SensrTrx allows you to track trends in your data allowing you to see over time how your plant is running. Using trends, you can easily see the effect of process or system changes over the long term. You can also notice when scrap is increasing or decreasing and quickly take action to resolve the issues.
Using SensrTrx users can easily setup alerts when scrap is higher than normal. These alerts can notify any employee that can benefit from this information, maintenance, supervisors or the operator of a line.
