Developing from the numerical control, or NC, machining measure which used punched tape cards, CNC machining is an assembling cycle that uses modernized controls to work and control machine and slicing instruments to shape stock material, e.g., metal, wood, plastic, composite, froth, and so on into custom parts and plans. While the Automatic CNC machine [เครื่อง กลึง อัตโนมัติ, which is the term in Thai] measure offers different capacities and activities, the crucial standards of the cycle remain to a great extent something similar all through every one of them. The fundamental CNC machining measure incorporates the accompanying stages:
- Designing the CAD model
- Preparing the CNC machine
- Converting the CAD record to a CNC program
- Executing the machining activity
Computer-Aided Design Model Design
The CNC machining measure starts with the formation of a 2D vector or 3D strong aspect CAD plan either in-house or by a CAD/CAM configuration administration organization. Computer-aided design programming permits fashioners and makers to deliver a model or delivery of their parts and items alongside the important specialized details, like measurements and calculations, for creating the part or item.
Plans for CNC machined parts are limited by the capacities, or ineptitudes, of the CNC machine and tooling. For instance, most CNC machine tooling is tube-shaped in this way the part calculations conceivable through the CNC machining measure are restricted as the tooling makes bent corner areas. Also, the properties of the material being machined, tooling plan, and work holding abilities of the machine further confine the plan prospects, like the base part thicknesses, most extreme part size, and incorporation and intricacy of inside cavities and provisions.
When the CAD configuration is finished, the originator sends out it to a CNC-viable document design, like STEP or IGES.
Computer-Aided Design File Conversion
The organized CAD configuration document goes through a program, commonly computer-aided manufacturing programming, to extricate the part math and creates the advanced programming code which will control the CNC machine and control the tooling to deliver the specially crafted part.
