Precision and CNC Machining, and Rapid Prototyping Machining is the most important part of manufacturing to remove material from a work piece in the form of chips. Machining is required where tight tolerances on dimensions and finishes are mandatory. Traditional Machining includes primers on turning, milling, drilling, and grinding. Machining is a part of the manufacturing of almost all metal products. Machining combines several processes, which can be divided in to following categories. â€Cutting- involves single-point or multipoint cutting tools, each with a defined geometry â€Abrasive processes, which include grinding â€Nontraditional machining processes, making use of electrical, chemical and optimal sources of energy There are three principal machining processes namely turning, drilling and milling. Other operations also include shaping, planning, boring, broaching and sawing. CNC Machining helps to cut curves as straight lines producing 3-D structures quite easily. Intervention of human involvement has considerably reduced because of CNC Machining. It has led to improved automation of manufacturing processes lending consistency and quality to work. CNC Machining allows flexibility and reduces duration of machining work. CNC Machining works through a computer "controller" that reads G-code instructions and drives a machine tool. CNC performs numerically directed interpolation of a cutting tool in the work envelope of a machine. CNC machining is done from files created by CAM software packages, without the need of producing a drafted paper drawing of the manufactured component. CNC Machining can be done at a stretch over night and over weekends without human intervention. CNC Machining operations work smartly with error detection features, enabling CNC machines to contact the operator's mobile phone if it finds that a tool has broken. New CNC machines use logical commands called parametric programming to do CNC Machining. CNC Machining Cycles are enhanced through Parametric programming allowing custom machining cycles like fixture creation and bolt circles. Through Parametric programming CNC Machining can create additional fixture locations on a work holding device and the machine can be manually steered to the new location to drill and form the patterns required to mount additional clamps at that location. Parametric programs are also used in CNC Machining to shorten long programs with incremental or stepped passes. A loop can be created with variables for step values and other parameters, and in doing so remove a large amount of repetition in the program body. Precision Machining involves an automated process that can work with precision CNC machining systems (computerized machines) to produce highly detailed parts effectively and quickly. Precision Machining services can be used for grinding, CNC milling and turning operations that require accuracy. Precision Machining process can utilize many types of plastics, alloys and steel. Aerospace industry relies on Precision Machining services for its needs. Rapid Prototyping helps you to design 3D models of your product for marketing purposes. Though the term includes word â€rapid,†the whole process can take from hours to days based on the customer needs. Rapid Prototyping started in late eighties and now it is effectively used with CAD (computer aided drafting) technologies to transform files into objects. It is seen that many people don’t want to buy Rapid Prototyping equipment because they consider it bulky and costly. Therefore, some Rapid Prototyping manufacturers are now offering units made specifically for office environments.
