There's many more reasons to purchase a vision system other than the cutting out of embarrassing defects. This article highlights the business values gained from installing an entire vision network.
There is more to a vision system than cutting out embarrassing defect!
We have been talking about planning and the technical benefits. Often as said, a system is purchased in reaction to customer pressure to stop embarrassing defects, but if planned and deployed in the correct location, a vision network will produce the following business values.
- Reduce customer claims and increased productivity on rework - Customer facing business benefits are probably the hardest to quantify and the most valuable. What price do you place on a lost contract? It can be part of any business strategy to include borderline product to fulfil a delivery. This is not a viable business strategy if the product quality has not been determined and stored. The cost of rework, if this product is returned, should be negated as the location of borderline issues will have been identified prior to shipping.
- Root cause analysis and process improvements - reduce inline waste and increase asset OEE. Vision networks integrated with sensor historians enable this.
- Smart converting - This is the use of data to optimize the follow on processes. An example of this is to rework a substrate roll prior to lamination. Why add the second layer to product that will be scrapped anyhow!
- Lower maintenance costs - can be expected through root cause analysis. Assets that are run at a steady output without constant stops due to quality issues will require less maintenance.
- Increased Output - Operators only deal with issues due to their process, there will be an increase in throughput.
Every operation is different and each factory produces for a variety of customers. Some of these customers are challenging price and quality on a weekly basis. The conversion processes differ, as to the suppliers and equipment. No one model fits all. The key is to take the time to consider each operation and site as a whole, and then work to a plan that will achieve your business objectives.
We have compiled a white paper on how to start planning your vision network.
