Since we will talk about Quality management processes under MES today, it would be more correct to mention the importance of Quality management only in the production.
First of all, what is Quality? In fact, there is no clear definition of quality, but with generally accepted definition: Quality means that the specified function and all measurable features of a product or service are and will always be the same.
Definition of quality according to Japan Industry Standards Committee: Quality is customer’s satisfaction.
Today, there is competition in every field. All businesses compete to stand out in this competition by offering their customers the best product at the most affordable price. The magic key of offering the best product at the best price is the use of quality management systems. Companies that fully implement quality processes both reduce their costs, increase customer loyalty by offering quality products to the market, and have the opportunity to find new markets. A brand that offers quality and affordable products has always been the first choice of consumers.
In addition, the management of quality processes has become an obligation rather than the initiative of the enterprise in many sectors today. For example, if you produce automotive spare parts, you must have certain quality certificates in order for companies that manufacture cars to buy parts from you, so you must apply quality processes.
The concept of Quality Control is built on the basis of incoming, process and final control applied within a process structure.
Methods applied to reach the goal or standard:
First Approval: Quality is a measure. Starting production after the first approval means stopping losses from the beginning.
Frequential Approval: To reduce production losses. As the mass production time increases, it becomes difficult to raise the correct product rating. Periodic checks reduce production losses.
Final Control:
And this stuation;
While managing quality control process, it is vital to manage quality documents and processes to improve production and service quality. In businesses, it has become almost impossible to follow the versions of thousands of quality documents paper based, have them approved and deliver them to the right people on time.
Quality control employees can quickly get the information about which station is waiting for approval via short messages sent to them. After going to relevent area, by providing data entry of quality measurements with the tablet application, it can quickly perform approval process It is also possible to see the product’s images to prevent mistakes.
“Continuous Improvement Activities” will continue both in internal processes and after shipment.The performance and activities of the communication and suggestion systems are measured with corrective and preventive activities created to ensure continuous improvement, and the system is continuously improved in the light of the data.
“Corrective actions should be developed”
Customer complaints, non-conforming products, non-conformities and suggestions determined in internal quality audit are basic parameters for initiating corrective actions.
MES ensures that the corrective and preventive actions and the customer complaints process are integrated with each other and work on the system. If deemed necessary at the end of the customer complaint process, CAPA process starts automatically. Corrective actions are also initiated according to process findings, suggestions, management reviews, internal waste and employee expectations.
In monitoring quality processes, MES enable us to make our work easier and right. In the planned work orders ; The right equipment, the right raw material/semi-finished product, the right personnel match are managed by MES. This will directly affect your quality processess.
Since it is necessary for companies with MES to control quality in long production processes and these quality rates can be compared with the expected default rates in real-time, any problem that is not visible but will constitute a quality problem is detected earlier.
When a new mold is loaded to the workstations, when a mold is newly maintained, or when any equipment setting, setup setting, calibration setting is made, the production goes through a certain test stage and quality control is required on the sample products. It is possible to record this digitally and to minimize these test times by MES.
For example, when a mold breaks down in a press, a maintenance worker comes and carries out repairs, and when this maintenance is finished, an SMS / mail notification is sent to the quality control team by MES. In this way, instead of using any paper or making a phone call, quality control team are instantly informed. It saves time and perform controls for the first productions that have been maintained or will be made with a new mold.
We can see another examples as in “Frequency Quality Control”. Let’s consider the work order sent as 10000 filled phone cases. However, according to their previous experiences, this company requires quality personnel to make checks every 1000 pieces. Because, after 1000 pieces of production, it is noticed that the covers are wearing out / burning / cracking. It allows to take action beforehand if any problem is experienced or thought to be experienced, by performing frequent checks on every 1000 pieces.
Highly sensitive measuring devices are used for quality measurements. In some fields, for example; in companies producing products for the pharmaceutical or medical sector, products with nanometer-sized lengths and milligram-sized weights must be measured precisely. Therefore, quality applications follow technology closely. Within the development of computer technologies, quality measurement processes have started to be carried out in automation in many fields.
As it is seen in the presentation on the screen, it will be very difficult to control the conductive tracks and dozens of micro-electronic elements on a circuit board by the human eye, so there is a computer that takes pictures on the production line. It checks the products according to the reference image loaded in its memory, and if it detecs any fault, it discards that card from the production line.
Of course, this process is recorded in the quality control system and processed into daily quality sheets. This whole process works with high technology, independent of people.
