High-Quality Customized Milling Service Parts Professional Aluminium CNC Milling Parts
Q9: Why do you need a CAD drawing to cut a simple rectangle, circle, or letter?
A: Even the simplest of shapes require a CAD drawing. That CAD drawing will be imported into CAM (computer-aided manufacturing) software. From that drawing, we would utilize the geometry to apply the toolpath to all entities intended to be machined. We also want to avoid the liability of cutting something that wasn't approved.
A CNC machine is a computer-controlled cutting machine used in the manufacturing world. It involves the use of computers to control the machine tools via G-code. Therefore, only a CAD drawing could be used in the CAM software that both gives us a visual representation and controls the machine.

Q10: Why do you need to design and machine a work-holding component to machine my parts?
A: CNC machines move at a very high rate of speed combined with a massive amount of torque. Maintaining the desired fixed position throughout the force of cutting ensures repeatable results. If the part moves while being machined, the high tolerances of the part will be compromised. Therefore machining a "jig" or workholding fixture may be required to complete the part.
