CNC Projects
A Computer Numerical Controlled (CNC) machine is a motorized maneuverable tool, which is controlled by a computer, according to specific input instructions. Instructions are delivered to a CNC machine in the form of a sequential program of machine control instructions such as G-code and then executed. The program is generated from a graphical Computer Aided Design (CAD) file. This means a computer converts the design produced by CAD, into numbers. The numbers can be considered to be the coordinates of a graph and they control the movement of a cutter. In this way the computer controls the cutting and shaping of the material without the use of a manual operator. The Camaster Stinger SR23 I've acquired is a 3-axis servo motor CNC outfitted with a 1HP HSD collet spindle. A servo motor is a rotary actuator that allows for precise control of angular positions. Spindles are more powerful and will maintain their full torque down to much lower RPMs than a router. Spindles use precision bearings, which means less run-out and much smoother and more accurate cutting. This particular machine has a repeatability or accuracy within 0.001 of an inch. Below are some projects done with this machine. All photos can be clicked on for better viewing. |
