San Luis Obispo's Cal Poly University is known for its innovative research facilities and projects. One such project is the Digital Fabrication Lab, also known as the d[fab]lab. The lab provides students and researchers with access to state-of-the-art manufacturing and rapid prototyping equipment, including a CNC router.
What is a CNC Router?
A CNC router is a computer-controlled cutting machine that can precisely and accurately cut a range of materials, including wood, plastic, and metal. The machine works by following a set of programmed instructions, or toolpaths, to guide the cutting tool to create complex shapes and designs.
Preparing the CNC Router
To use the CNC router at the d[fab]lab, students need to prepare the bed of the machine and their material stock. The bed of the machine is 4'x 8' and can currently accommodate up to 4" of Z height. The student should have their digital file ready, and toolpaths are generated with RhinoCAM, a plugin available on the eight computers in the d[fab]lab.
Learning RhinoCAM
RhinoCAM is a software plugin that allows students to create toolpaths for CNC machines. However, the technicians in the d[fab]lab are unable to teach this software to students, which emphasizes the need for students to take the initiative to learn it. Learning RhinoCAM is essential to creating toolpaths that are specific to their design.
Taking the Initiative to Learn
To make the most of the digital fabrication lab and its equipment, students must take the initiative to learn. This includes not only learning RhinoCAM but also understanding the properties of the materials they plan to cut. For instance, wood and metal have different properties and require different toolpaths to produce quality results.
The Importance of Material Stock
The material stock used in a CNC router plays a crucial role in determining the quality of the end product. Therefore, it is essential to select the appropriate material for the job and prepare it accordingly. Students must ensure that the material is clean, flat, and well supported. They must also consider the thickness of the material, as this will determine the machine's Z height.
Incorporating CNC Router in Educational Programs
The availability of CNC routers in educational institutions is an excellent opportunity for students to learn about digital fabrication and manufacturing. A CNC router can be used to create endless possibilities, from designing intricate parts for projects to creating prototypes. CNC routers can encourage students to think creatively and gain practical experience in an advanced technology that is shaping the future of manufacturing.
Conclusion
In conclusion, the CNC router is a powerful tool that has revolutionized the world of digital fabrication. The Cal Poly d[fab]lab provides students with access to this cutting-edge technology, inspiring innovation and creativity. However, to utilize this resource effectively, students must take the initiative to learn RhinoCAM and understand the properties of different materials. Incorporating CNC routers in educational programs will prepare students for the future of digital manufacturing and ensure that they are well-equipped to meet the industry's demands.
