CNC Cutting Machine Practice Test

The primary motion type used for drilling or tapping is point-to-point motion. In this context, drilling and tapping are processes that involve moving the cutting tool directly from one point to another without a continuous path. This motion allows the machine to precisely align the drill or tap at specific coordinates, engaging with the material at designated points to create holes or threads.

Point-to-point motion is essential in these processes because it enhances accuracy and efficiency, ensuring that each drilling or tapping operation is executed at the exact location required. This method contrasts with other types of motion, such as curvilinear or circular motion, where the tool would move along a predefined path instead of to specific points, which would not be suitable for these applications. Straight-line motion can describe some components of the drilling process, but it does not encompass the overall functionality required for effective drilling and tapping, which is more focused on pinpoint accuracy rather than continuous straight movements.
