In machining, surface finish directly affects the function, service life and sometimes the safety of a part. Yet it is common to see drawings where surface finish is either missing or over-specified, leading to unnecessary costs and delays. Here’s how to know what to specify, where to specify it, and when to avoid asking for too much. (...)

In machining, the choice between a conventional machine and a CNC machine (Computer Numerical Control) directly affects the cost, lead time, quality and flexibility of a project. Contrary to common assumptions, CNC is not always the best solution. In many situations, a conventional machine remains more efficient, faster and more economical. Here is a practical guide to help understand when to choose one or the other. (...)

In machining, tolerances play a key role. They determine the function of the part, its final quality and its manufacturing cost. Yet they are often misunderstood or over-specified, which leads to longer lead times and unnecessary costs. Here is how to understand when tightening a tolerance is justified — and when it is better to avoid it. (...)

A machining drawing is the common language between the client and the machine shop. When it is clear, it allows efficient, precise and unambiguous manufacturing. When it is incomplete or misinterpreted, it can lead to delays, additional costs and non-conformities. Here are the most common mistakes encountered when reading machining drawings — and how to avoid them. (...)

In 2026, the machinist is no longer just the person who “runs a machine.” They have become a central contributor to industrial performance, at the intersection of technology, craftsmanship and technical judgment. In a context of labor shortages, shop modernization and increasing quality demands, the role of the machinist has never been more strategic. (...)
