In the machining industry, technical drawing, also known as engineering drawing, refers to the creation of detailed, precise, and accurate illustrations of parts and components to be manufactured. These drawings provide a clear view of the part to be machined by providing key information about dimensions, annotations, tolerances, surface finish and other features required during machining.
Machinists, designers, architects, and engineers use technical drawings as a communication tool to convey information and ideas. Knowing how to read technical drawings can help ensure that a part meets its design requirements and is suitable for its intended use. The drawings are clear and follow specific standards, conventions, and symbols to ensure that the information conveyed is accurate, consistent, and easy to understand.
Technical drawings are essential to improve the efficiency of the machining process. They reduce the need for trial and error, allowing machinists to produce parts that meet required specifications on the first try. This increases the efficiency of the machining process and reduces time and production costs.
Technical drawings are an important part of quality control in the machining industry. Technical drawings provide standards for measuring and testing machined parts. Additionally, these drawings enable quality control inspectors to verify that machined parts meet required specifications prior to use.
Technical drawings are critical in turning and milling operations because they specify the required surface finish and other key features. This in turn ensures that the final product meets the required specifications. Technical drawings are crucial in drilling because they provide the machinist with the dimensions and tolerances needed to machine the desired hole. This includes hole size, depth and location. Other common applications include grinding and EDM.
