Rapid prototyping is a process where physical objects are being created using free form fabrication. It is used at a wide level in various industries. In the process, rapid prototypingtakes virtual designs from animation and modelling based software. It then transforms these virtual designs in to physical space.
What is CNC?
Computer Numerical Control (CNC) is a machining process where a rotary device like a cutting machine is being operated by a computer and used to cut a specified shape. Various steps are followed and cutting tools are changed for getting the desired shape. During the fabrication process, the systematic shape is being built using high precision and finishing.
CNC milling has been serving the automation and animation industry since a considerable period. Even though there are various other applications available for cutting too, the accurate and the swift performance by CNC has no match till date.
Benefits of Using CNC Milling Machines in Rapid Prototyping
1.CNC machininghas been designed to fulfil a specific list of milling task. Depending upon the dimensions and orientation of the cutting tool, there are different types of milling machine centres âEUR" horizontal cutting and vertical cutting.In addition, according to the size of the component, there are large size machines and small size machines. This means that one has several options depending upon the orientation and size of component.
2. CNC machines are being controlled by software called âEUR~Integrated Control SoftwareâEUR(TM). With the help of a proficient G code programmer, the machine can be operated to provide even more precise cutting and orientation. This efficient software provides updates that help in improving the performance of the machine over the long run. In order to ease the task of a programmer, various touch screen machines are being introduced to control the software all on its own without any manual interference.
3. CNC millinghas the ability to fabricate a wide range of components. Different CNC milling machines are used in factories and work places. Some of these are 3 axis, 4 axis and 5 axis centres.More axes the machine has, more detailed and precise operations can be performed. Depending upon the type of detailing one requires in the model, requisite axis centre can be chosen to create the design.
4. Many a times, it happens that the model lacks the requisite precision level and orientation. This leads to wastage of time and resources as well.However, in case of CNC machines there is a special chip management system. This specialised system helps in knowing the precision level and the orientation angles on prior basis.This way one can avoid the wastage and create required models at once.
5. In non-CNC milling machines, the operators have to work near to the work place where the cutting and drilling operations are being performed. This may affect them in case of an error in operations or an accident due to machine failure. In CNC milling machines, the operators work in an enclosed area at a considerable distance from the machines using integrated softwares.
