CNC machining tolerances for assembly fit are important. They help parts line up and work well. They also make sure parts last a long time. When you set tolerances, you pick the size range that is okay. This keeps parts steady and accurate. Bad tolerances can cause parts to not fit right. They can make parts wear out too fast. Parts may shake or even break during assembly. Tolerances help stop things from breaking or being unsafe. Wrong tolerances can mess up the whole assembly. This can make products not last as long. If you ignore tolerances, you may spend…
