• Evaluate design drawings for new or changed tools by measuring dimensions on the drawings and comparing them with the original specifications
• Prepare layouts and drawings of parts to be made and of the process for putting them together
• Discuss changes with coworkers—for example, in the design of the part, in the way it will be made and put together, and in the techniques and process they will use
• Review instructions and blueprints for the project to ensure the test specifications and procedures are followed and objectives are met
• Plan, produce, and assemble new or changed mechanical parts for products, such as industrial machinery or equipment
• Set up and conduct tests of complete units and of parts as they would actually be used, as a way to investigate proposals for improving equipment performance
• Record test procedures and results, numerical and graphical data, and recommendations for changes in products or test methods

Compare test results to design specifications and test objectives
