The standard specifies the acceptable deviation in surface quality and geometric shape of the channel. It emphasizes that the surface must be free from harmful defects, and there should be no noticeable twisting or distortion. The permissible limits for channel wave bend (also known as cutter bend) and key groove dimensions (such as h, b, d, t, etc.) are clearly defined along with their tolerance ranges. Common issues in channel geometry include irregular angles, uneven leg lengths, and misalignment between the legs. These deviations can affect the performance and structural integrity of the component, making it essential to adhere to the specified tolerances during manufacturing. Ensuring compliance with these standards helps maintain product reliability and consistency across different applications.
