How Glass CNC Machining Works

CNC (computer numerical control) milling machines evolved from numerically controlled machines developed to create precision rotor blades for helicopters in the 1950s. In the early 1970s, these machines began to be controlled by computers running programs to operate the various motions of the milling tools.

Basically, glass CNC machining in Sydney automates everything a human operator would have to do to manually mill a piece of glass via information input into the CNC program. Then, the machine replicates with great precision each action to mass produce milling or cutting of glass at a rate and accuracy that cannot be duplicated by a human operator.

Motion Control with CNC Machining

Glass CNC machining utilizes at least two-and as many as four-directions of motion that can be directly programmed by the software. These are called axes. An axis may be a linear direction or circular. The more potential axes a CNC machine is capable of, the more complex and expensive the machine is. Axes are usually designated by letters. Typically, linear axis are designated X, Y, and Z. Circular or rotary axis are normally A, B and C.

Software for CNC Programming

The computer program utilized in glass CNC machining is written in a language called G-Code. The program issues instructions to stepper motors that convert electronic signals into highly accurate mechanical movements that guide the milling tool. The format of the language is configured in sentences and the CNC controller executes the instructions sequentially, one step at a time. A series of words specific to CNC programming communicate to the milling or cutting machine what it's supposed to do.
