Machines Used In Cnc Machining Process And Characteristics

Cad software is used to create things by designing and drawing using geometric shapes to construct a model.

Cad and cnc meaning. Cnc means computer numerical control. Computer aided design cad is a computer technology that designs a product and documents the designs process. Cadcam software is used to design and manufacture prototypes finished products and production runs. With cnc each object to be manufactured gets a custom computer program usually written in an international standard language called g code stored in and executed by the machine control unit mcu a microcomputer attached to the machine. Cad is an acronym for computer aided design and cam is an acronym for computer aided manufacturing. Cad may facilitate the manufacturing process by transferring detailed diagrams of a products materials processes tolerances and dimensions with specific conventions for the product in question. Cad computer aided drawingdrafting and cam computer aided manufacturing are computer technologies used for mainly product designing and manufacturing purposes where former is used in designing of the product through some designing software while latter involves software for controlling the machines in the industries such as cnc machines. Cadcam stands for computer aided design computer aided manufacturing. Cnc machinists can either write g code from scratch modify existing g code or generate g code using cam software. Cam software can generate g code from either images or cad files. The numbers can be considered to be the coordinates of a graph and they control the movement of the cutter. In this way the computer controls the cutting and shaping of the material. The program contains the instructions and parameters the machine tool will follow such as the feed rate of materials and the positioning and speed of the. In todays extensive cad industry there are also cad editing programs that automatically convert cad files into g code. Numerical control also computer numerical control and commonly called cnc is the automated control of machining tools drills boring tools lathes and 3d printers by means of a computera cnc machine processes a piece of material metal plastic wood ceramic or composite to meet specifications by following a coded programmed instruction and without a manual operator.

This means a computer converts the design produced by computer aided design software cad into numbers.
