Reviewing Schematics

Manufacturing prints are an essential part of the CNC machining process. They provide a detailed plan for how a part or product should be designed and manufactured. However, if the manufacturing prints are not well-designed or reviewed, it can lead to costly mistakes and delays in production. In this whitepaper, we will discuss the 5 things you need to review on your manufacturing prints before you send them to a manufacturer to ensure a successful production process.

1. Accuracy of Dimensions:

The first thing you need to review on your manufacturing prints is the accuracy of the dimensions. All dimensions should be clearly labeled and precise and represent the critical pieces for manufacturing. It is important to ensure that the dimensions match the intended design of the part or product, and anything left out needs to be discussed and identified with your customer. If the dimensions are incorrect, it can lead to errors during manufacturing, resulting in parts that are out of tolerance, cannot be used, and cost thousands of dollars to make correct.

2. Compatibility with Manufacturing Process:

The second thing you need to review on your manufacturing prints is the compatibility with the manufacturing process. It is essential to consider the manufacturing capabilities of the manufacturer before creating the prints. For example, suppose a particular feature requires a specific machine or tool that the manufacturer does not have. In that case, it can cause delays or additional costs as it may need to be manufactured at multiple locations. It is important to ensure that the manufacturing prints are designed to be compatible with the manufacturer’s equipment and processes that you intend to use.  You should also consider the cost to the manufacturer when determining the best process to use.

3. Material Selection:

The material selection is the third thing you need to review on your manufacturing prints. Selecting the appropriate material for the intended application and manufacturing process is important. For example, if a part needs to be heat-treated, the material should be able to withstand high temperatures without warping or deforming. It is also important to ensure that the selected material is readily available and cost-effective.

4. Tolerances:

The fourth thing you need to review on your manufacturing prints is the tolerances. Tolerances are the acceptable range of dimensions for a part or product. It is important to ensure that the tolerances are reasonable and achievable by the manufacturer. If the tolerances are too tight, it can lead to additional costs and longer lead times. If the tolerances are too loose, it can lead to parts that do not fit together correctly or do not function as intended.

5. Clear and Concise Labeling:

Labeling is the fifth thing you need to review on your manufacturing prints. All parts, features, and dimensions should be clearly labeled and easily read. It is important to use consistent labeling throughout the manufacturing prints to avoid confusion. This includes labels for different views, sections, and dimensions. Clear and concise labeling can help avoid errors and ensure the parts are manufactured correctly.

Conclusion:

Reviewing your manufacturing prints is an essential step in the CNC machining process. By checking the accuracy of dimensions, compatibility with manufacturing processes, material selection, tolerances, and labeling, you can avoid costly mistakes and ensure a successful production process. Reviewing your manufacturing prints can save time and money in the long run and help ensure that your parts and products meet the intended design and function as intended.
