How familiar are you with CNC milling? It refers to a machining process that removes material from workpieces in order to produce custom parts. Different types of materials can be used in the machining process, like glass, wood, plastic, and metal.
The precision and versatility of this technology have made it prominent in the aerospace and medical industry. There are various providers of products designed with precision machining, creating innovative manufacturing solutions for customers.
OVERVIEW OF THE PROCES
In the same fashion as the other CNC machining processes, milling has to be computerized in order to operate machine tools whose job is to shape and cut materials. This procedure involves the same stages of production, starting by creating a CAD model, converting this model into a format compatible with a CNC program, setting up the milling machine, and performing the given operation.
The CAD model designed at the start of the process is either a 2D or 3D design of the part. The job of operators is to prepare the machine by securing the workpiece to the work surface of the machine and attaching the necessary tools. Once the machine is prepared for the process, the operator sets the program in motion, which instructs the machine to perform the required tasks.
After the initiation of the CNC cutting process, the machine is expected to rotate the tools for cutting at a given speed. Parts are shaped by gradually removing material until the desired form is achieved. In the beginning, the cutting tools remove only tiny pieces of the entire workpiece to create an approximate form. Afterward, the workpiece is subjected to another more accurate and precise procedure to ensure the part has the right features.
