Short Description:
A computer numerical control (CNC) router is a computer-controlled cutting machine which typically mounts a hand-held router as a spindle which is used for cutting various materials, such as wood, composites, metals, plastics, glass, and foams.
Idea Details:
The idea of making a compact and low cost 3 axis CNC Engraver Machine comes from increase in demand of low cost and Portable machine..As the increase in rapid growth of technology and software available..It is not difficult so we decided to make a machine which can mill the wood, plastics, thin sheet and alloy..Design and Fabrication is done using a Precision Stepper Motor that combined with liner 12 mm bearing arrangement on the gantry type aluminum structure on which the x and y axis is smoothly slide on rail bearing and for z axis we use Threaded rod and arrangement for up and down motion that increases and more precisely result obtained..It is an Microcontroller (Arduino uno) based embedded system with a standard pc user interface software for easy drawing..The System also features an offline G code parser and then interpretated on the microcontroller from a USB. Improved procedures are employed in the system to reduce the computational overheads in controlling a 3-axis CNC machine, while avoiding any loss in overall system performance.
