Quality Management Through Process Control In Metal Fabrication

By Reto Hug


Maintaining quality in products is essential to any business. Taking a wider stance, maintaining product quality can be achieved through controlling the quality of the processes that it takes to fabricate that product. An example of controlling of a process would be to take calculations of something when it is operating optimally so that the calculations can be compared to measurements in the future, to ensure that top quality functions are still in place. For example, strain on machine frames can be assessed via a strain monitor to assess quality. The machine's frame strain must have been assessed when it was operating at its best and manufacturing quality parts so that measurements from that assessment may be employed as a control to measure against when the machine starts operating in a manner that is not optimal. This can assist in measuring the whole production process. Monitoring processes for discrepancies is a revolutionary new way of looking at quality assurance rather than looking for flaws in parts. If a process manufactures quality parts and is able to be repeated, this is a model scenario for a manufacturing environment.

Process Valuation Monitoring

The characteristics of process variation monitoring involve overseeing all of the production but not needing to add any additional steps in the process. Also, if a part is found to be defective, processing is stopped so that there is no wasting of time in manufacturing defective parts and the bad parts do not lead to squandered materials. When process variation monitoring is put in place, maintenance workers do not have to insist that machines are turned off at periodic times so that they can carry out their maintenance tasks or worry about not carrying out their maintenance often enough, and the machines don't perform. In this setting, the maintenance occurs only when it is needed. Maintenance prices will therefore go down and efficiency in machine activity and operation as a whole will increase.

Tooling will only be swapped on an as-needed basis in this environment so money will be recovered because the tooling will not be replaced too early or too late. The final trait is that all staff in the company will concentrate on process instead of the actual parts being made so gains will be found in several areas such as in the quality of the final product.

For process control to be effective in any environment, it needs to have a goal that is focused and comprehensive. There needs to also be a system of assessment in place so that it can be found if the aim is attainable or at what point it will have been attained. There should also be a set of procedures with responses that are anticipated to operate, so that effectiveness can be assessed.

Process Control: Case Study

At Maloya, they utilized process control in their manufacturing setting. They utilized it as part of their scheduled maintenance of machinery which included regular calibration of the machines. Their laser machines were fitted with test elements and these would be assessed and the results recorded to make sure that the machine was delivering accurate results within the original equipment manufacturer (OEM) specifications. This afforded Maloya with an established process capability to guarantee that their methods are working at their best which then translates to their quality levels and standards. This process can also be duplicated in regions such as machining and welding, as well as in developing work centers.

By instituting process controls, you will discover it a productive method of maintaining quality management in a metal manufacturing setting. Rather than focus on the parts, concentrate on the processes and all will fall into place if done effectively.
