This sub-service identifies potential collisions, optimizes machining strategies, and validates tool paths before actual production, minimizing errors, reducing material waste, and enhancing overall machining quality.
About CNC Modeling
CNC modeling, short for Computer Numerical Control modeling, is a technique used in manufacturing to create detailed and precise parts and products. It involves using computer-aided design (CAD) software to design a 3D model of the part or product. This model is then converted into instructions, known as G-code, which guides the CNC machine in cutting and shaping raw materials, such as metal, wood, or plastic, to match the design. CNC modeling offers several advantages over traditional manual machining methods. It allows for higher precision and accuracy, as the machines can follow the design specifications with great detail. This results in parts that fit together perfectly and perform their intended functions reliably. CNC modeling also enables faster production speeds, as the machines can work continuously and do not require breaks or rest periods like human operators. Additionally, CNC modeling is highly versatile, capable of producing complex shapes and designs that would be difficult or impossible to achieve with manual methods. This makes it ideal for manufacturing customized or low-volume parts. Furthermore, CNC machines can be programmed to produce multiple identical parts, ensuring consistency in quality and dimensions. Overall, CNC modeling is a powerful tool in modern manufacturing, offering efficiency, precision, and versatility in producing high-quality parts and products.

CNC Modeling FAQs
How do you convert a CAD model to a format that can be used by CNC machines?
How do you convert a CAD model to a format that can be used by CNC machines?
To convert a CAD model to a format that can be used by CNC machines, you need to first export the CAD model to a commonly accepted format like STL, IGES, or STEP. Then, import this file into a CAM (Computer-Aided Manufacturing) software, which will generate the necessary G-code or M-code that the CNC machine can read and execute.

Tutors & Services Philosophy
Don't Learn Alone
Professionals these days are sitting alone and staring at their computers. They spend years searching online for tools that will increase their workplace efficiency—digging through forums and watching lengthy videos for the right CAD or visualization tip.
Sometimes they just have one small question that would take a person two minutes to answer, but customer support lines are a thing of the past. Big companies will direct you to an FAQ that will hardly begin to answer your question.
Bring Back the Human Connection
We strive to bring human connection back to the work environment. Our tutors work directly with you to solve your problems, similar to the way an apprentice works hand-in-hand with a skilled professional.
Screen-share technologies like Zoom have allowed us to work together in real time. We can see each others' screens and cursors, switch presenters to share information easily, and even turn on webcams for a more human interaction. Learn efficiently across workflows like architectural rendering, interiors, mechanical modeling, and construction documentation.
Tutors, Services, or Both
Sometimes our clients want to learn a program from beginning to end; sometimes they completely hand over the services to us; and other times, they want something in between.
Some clients want to be able to use the program on a basic level and let us do the hard stuff. Others want to co-work with us, supervising our work to ensure their artistic vision is realized. Along the way, they learn the tools—whether that’s SketchUp, Blender, Fusion 360, Revit, or AutoCAD.
By the end of the process, some clients are able to wean themselves completely off of our services and are empowered to do the work themselves. If they get stuck or behind on a deadline, they use us as a lifeline. They can call anytime—even if it’s just a 10-minute question—we are here to help.
