Developing Quality Maintenance. Consolidate Checking Methods

Each of the 4-M conditions established in Step 7 must be controlled to ensure 100% quality. However, they are usually very numerous, and the time required to check all of them can strain available resources. To make them manageable, they must be fixed (made so that they cannot change with time and do not need to be checked so often) and consolidated (grouped to reduce their number) following the…

Eliminate Flaws in 4-M Conditions and Finalize

In this step 6, we actually implement the improvements proposed in Step 5. The results are then assessed at prescribed intervals to ensure that they satisfy the product’s designed quality characteristics (see Figure “Eliminating Flaws in 4-M Conditions through Kaizen”). Eliminating Flaws in 4-M Conditions through Kaizen On completing Step 6, we revise the conditions and standards identified in…

Developing Quality Maintenance. Step 5 Analyze Situations where the Conditions for Building in Quality Are Unclear

In Step 5, we employ methods such as P-M Analysis, FMEA and design of experiments, to find ways of correcting deficiencies listed in the Deficiencies Chart at Step 4 that did not seem to have an obvious solution (where the conditions required for building in quality are hard to specify). Figure “Example of P-M Analysis of Ordinary PVC Drying Process” shows an example of P-M Analysis. Example of…

What is Quality Engineering or Taguchi Method?

Quality engineering is also called the Taguchi method because most of the system was constructed by Dr. Genichi Taguchi, and although it is highly recognized worldwide, it requires considerable effort to understand the whole picture because the contents are quite complex.Despite the fact that it is an unfinished technique with new mathematical proposals, the reason why it is used by well-known…

The Structure of Equipment Maintenance

Equipment maintenance can be defined as preventing machines from breaking down by selecting what type of maintenance should be used, which parts of which machines, formulating maintenance standards, and then systematically maintaining and controlling the machines following a maintenance calendar. This definition can be split into the following five component elements, which form the structure of…

Maintenance Planning and the 4 Phases

Any attempt to maintain the equipment systematically and cost-effectively will be frustrated if it continues to fail regularly and the intervals between those failures are always changing because this makes it impossible to put together a dependable maintenance plan. To begin with, breakdowns must be systematically reduced by following the four-phase approach illustrated in Figure “The 4 Phases…

Focused Improvement – The Steps of P-M Analysis. Steps 5 – 8

Step 5: Work out what the ideal state (the standard values and criteria) should be The next step is to examine each of the possible causes of the phenomenon identified in the previous steps and establish a criterion for determining whether it is as it should be or not. As users of production machinery, we are very often not provided with any standards by which we can judge whether the equipment…

Focused Improvement – The Steps of P-M Analysis. Steps 1 – 4

Step 1: Clarify the phenomenon A phenomenon is an observable event or occurrence, and ‘clarifying the phenomenon’ means identifying what is causing the problem by careful observation of the facts. If the phenomenon (what is actually happening) can be pinpointed, the problem is halfway to being solved. Conversely, a P-M Analysis conducted on a phenomenon that has not been accurately identified…
