What must dimensional tolerance limits on forms be in relation to the final product tolerance?

Dimensional tolerance limits on forms must be less than the final product tolerance to ensure that the manufacturing process can produce a final product that meets the specified tolerances. This means that if the dimensional tolerances on the forms are set tighter than those of the final product, it enables a margin for error during production while still being able to achieve the desired specifications for the end product.

Setting the form tolerances less than those of the final product accounts for variations that may occur during manufacturing, such as potential changes in material properties or external conditions. This approach helps maintain quality control throughout the manufacturing process and ensures that the final product consistently meets customer and regulatory requirements.

By having tighter tolerances at the form level, manufacturers can better manage the variability that might arise later in production, ultimately leading to higher quality in the finished items. Therefore, it’s crucial for the dimensional tolerance limits on forms to be less than the final product tolerance to facilitate successful production outcomes.
