CNC Cutting Machine Practice Test 2025 – Complete Exam Preparation

CNC machines are primarily distinguished from manual machines by their ability to operate through computer-controlled automation. This means that CNC machines rely on computer software to automate the machining process, allowing for precise control over cutting tools and movements. The automation enables complex shapes and patterns to be produced with high accuracy and repeatability, which is difficult to achieve with manual machines that require human intervention for every adjustment and movement.

While some manual machines may handle large weights, this feature is not exclusive to CNC machines. Operational speed can vary widely among both CNC and manual machines, but it is not a defining characteristic that differentiates them. Additionally, manual machines generally involve more complex operations due to the need for constant physical adjustments and monitoring by the operator, which is contrary to the automated operation offered by CNC technology.
