The correct answer is: D. it simplifies the trial-and-error method
CAD, or computer-aided design, is a process that uses computer software to design and create 2D and 3D models. It is used in a variety of industries, including manufacturing, architecture, and engineering.
One of the major benefits of using CAD in tool design is that it simplifies the trial-and-error method. With CAD, designers can create multiple iterations of a design quickly and easily, without having to build and test each one. This can save a significant amount of time and money.
In addition, CAD can be used to create detailed 3D models of tools, which can be used to evaluate the design for fit, function, and manufacturability. This can help to identify potential problems early in the design process, before they become costly to fix.
Overall, CAD is a powerful tool that can be used to improve the efficiency and effectiveness of tool design. It can help to reduce costs, improve quality, and shorten the design cycle.
Here is a brief explanation of each option:
- Option A: product design represents approximately one-half the engineering costs. This is not necessarily true. The cost of product design can vary depending on the complexity of the product and the level of detail required.
- Option B: tool motions can be checked to see if there is interference between the tool and the object. This is true, but it is not one of the major benefits of using CAD in tool design.
- Option C: there is better coordination in the materials-handling area. This is not necessarily true. The use of CAD can help to improve coordination in the materials-handling area, but it is not one of the major benefits of using CAD in tool design.
- Option E: None of the above. This is not the correct answer. The correct answer is: D. it simplifies the trial-and-error method
