Tolerance refers to the acceptable deviation from a specified dimension or feature in a design. In CNC machining, parts are rarely produced with absolute perfection due to various factors such as material properties, machine capabilities, and environmental conditions.

Manufacturing quality problems can seriously affect product performance, customer satisfaction, and a company’s reputation. A collaborative effort between engineers and manufacturers is essential to ensure consistent product quality and minimize the risk of defects. Engineers bring their technical expertise, design insights, and product knowledge, while manufacturers possess hands-on experience and production capabilities.
