CNC Technology

2016-06-07


With skilled craftsmen dwindling in numbers, CNC machines quickly becomes the technology of choice for large and small woodwork shops.

Computer Numerical Control (CNC) is for operating machine tools with computer programmed instructions. They are keyed into a computer and sent to automatic devices; typically rotary servo mortors driving ballscrews, or other mechanisms such as a rack and pinion, or timing belt drives.

CNC systems are used to execute a series of precise movements and operations. Recent developments such as automatic part measurement and parametric scaling of parts, allow an operator to upload a set of instructions.

It also lets the computer calculate the exact cut path according to predefined parameters. The control of these machines range from simple linear positioning, complex contouring to laser cutting. CNC has been applied to nearly every type of woodworking operation, which includes sawing, routing and sanding.
