1：WHAT IS CNC MACHINING? AN OVERVIEW OF THE CNC MACHINING
CNC machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery.
Short for “computer numerical control,” the CNC process runs in contrast to — and thereby supersedes — the limitations of manual control,where live operators are needed to prompt and guide the commands of machining tools via levers, buttons and wheels. To the onlooker, a CNC system might resemble a regular set of computer components, but the software programs and consoles employed in CNC machining distinguish it from all other
forms of computation.
CNC MACHINE PROGRAMMING
In CNC, machines are operated via numerical control, wherein a software program is designated to control an object. The language behind CNC machining is alternately referred to as G-code, and it’s written to control the various behaviors of a corresponding machine,such as the speed, feed rate and coordination.
Basically, CNC machining makes it possible to pre-program the speed and position of machine tool functions and run them via software in repetitive, predictable cycles, all with little involvement from human operators. Due to these capabilities, the process has been adopted across all corners of the manufacturing sector and is especially vital in the areas of metal and plastic production.
For starters, a 2D or 3D CAD drawing is conceived, which is then translated to computer code for the CNC system to execute. After the program is inputted, the operator gives it a trial run to ensure no mistakes are present in the coding.
