设计过程往往会带来制造方面的挑战，设计师必须能够了解这些挑战，以便将其最小化。通常，机械工程专业学生的经验水平不足以让他们考虑制造工艺对设计施加的限制，他们经常设计出难以制造或根本无法制造的零件。这项工作描述了一个系统的开发、实施和分析，该系统用于快速为学生提供考虑加工工艺制造挑战所需的知识。一组实验组学生接受了一个软件包（SculptPrint）使用方面的培训，该软件包提供车削过程的可视化，并教授如何操作各种计算机数控（CNC）机床。另一组单独的对照组学生接受了手动机床操作方面的培训，且无法使用车削可视化内容。对两组学生都进行了知识评估，以衡量他们对可制造性多个主题的理解。对调查结果的分析表明，通过采用制造过程的可视化，可以极大地提高学生对车削过程中几何限制的理解。
The design process can often introduce manufacturing challenges, and designers must be able to understand these challenges in order to minimize them. Frequently, the experience level of mechanical engineering students is insufficient for them to consider the limitations that manufacturing processes impose upon design, and they often design parts that are either difficult or impossible to manufacture. This work describes the development, implementation, and analysis of a system used to rapidly provide students with the knowledge they need to consider manufacturing challenges for machining processes. An experimental group of students was trained in the use of a software package (SculptPrint) that provides visualizations of the turning process and taught how to operate various computer numerical control (CNC) machine tools. A separate control group of students was trained on the operation of manual machine tools and did not receive access to the turning visualizations. Knowledge assessments were given to both groups to measure their understanding of a variety of topics in manufacturability. Analysis of the survey results indicates that student understanding of geometrical limitations in the turning process can be dramatically improved by employing visualizations of manufacturing processes.
