Becoming an Excellent Process Engineer” --8--- “How to Become an Excellent Machining Engineer?” First and foremost, it is certain that universities cannot directly train technicians; the development of technicians requires experience and practice. Even with proper manufacturing processes, it cannot be guaranteed that everything will go smoothly, as there are many other factors that influence product quality. At work, it is necessary to continuously understand and reinforce the concepts learned in school, such as what craftsmanship is and what the goals of craftsmanship are What are the properties and characteristics of the process? Once the concept is clear, one can identify the key factors among many others for analysis and reasoning while thinking (this is how initial selections are made among various conditions in a manufacturing process), and finally conduct quantitative calculations on the few remaining options. For example, when climbing to the top of a mountain, there are different paths one can take, but you won’t use all of them. You will choose the one that seems reliable, describe it, optimize it by removing any unnecessary complexities, and thus arrive at the correct path to the summit – and that is more or less what craftsmanship entails. In this example, different people and different conditions will lead to different results. It’s also not possible to determine which path is the best, as everything is constrained by its own conditions; moreover, there are many paths that have not yet been tried. Therefore, the process involves uncertainty, somewhat similar to indeterminate equations, due to the large number of factors involved. Many newcomers feel lost and struggle to find the right approach, and this is probably mainly due to the uncertainty surrounding the techniques involved. So often, if what you do differs from the standard techniques, it doesn’t necessarily mean it’s wrong. Let’s first address the issue of explanations regarding the manufacturing process. The rule is that any explanation related to the process must serve to improve product quality, and the authority to provide such explanations lies with the process design department. Now, let’s talk about the limitations of process instructions. A process cannot cover everything; it should simply tell the operator what to do and what requirements need to be met. It shouldn’t tell the operator that they need to warm up the machine for 10 minutes first or that gloves are not allowed – such things are unrelated to the process itself. Those details should be included in the operation manuals or safety procedures, as the operator will already be familiar with them by the time they start working with that process. You will specify that the roughness of the surface to be processed should be RA6.3, and that there should be no scratches of 0.1 or more on the outer surface – these are the minimum requirements; anything higher than these is acceptable. All the requirements related to the processing process define these minimum standards; they represent a boundary or limit. The limitations of the processing process lie in these standards, as they constitute certain finite conditions that must be met in order to produce the product. When it comes to the development of manufacturing processes, many constraints must be taken into account. Generally, there is a preliminary overall process plan, a production schedule, design specifications, etc. The majority of the process components should be based on established technologies, while new technologies are used for certain key aspects. Therefore, it is necessary to carry out process trials to master these new technologies and ensure their controllability; after that, specialized organizations are involved to conduct evaluations and confirmations. After trial operation, the process can meet the task requirements; upon evaluation, it can be approved and put into execution.
