Precision machining is essential in creating and designing the machines, parts, tools and other hardware essential to modern manufacturing to maintain process control and tolerances that operate under extremely tight specifications. It is used to compose many large and small objects and their components that we use in our daily lives. If an object is made up of many small parts, those parts often need to be fabricated with precision machining to ensure they fit together precisely and function properly.
Precision machining is a subtractive process used in situations where material needs to be removed from raw materials to create a finished product. Precision machining can be used to create a wide variety of products, items and parts for any number of different objects and materials. These parts often require tight tolerance variations from nominal size and part-to-part, meaning there is not much room for error in the production of the part. Repeatability and well-controlled tolerances are hallmarks of precision machining.
Components, parts and finished durable products designed to maintain extremely tight tolerance margins and a high degree of durability are common drivers that are essential to the use of precision machining. For example, parts that need to work together as part of a machine may need to always be aligned within a specific margin of 0.01mm to 0.05mm. Precision engineering and machining help ensure that these parts are not only manufactured with precision, but produced with this level of precision time and time again. Another common application of precision engineering might be when a tool or component needs repair or restoration. After a period of use, a tool or part of an object may require machine calibration, grooving or welding to restore it to its original state. This can also be done by precision machining.
Precision machining is a subtractive process in which custom software, engineering tools and process steps are used with raw materials such as plastics, ceramics, metals or composites to create the desired delicate product. Precision machining typically follows instructions given by computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. These programs and blueprints enhance the ability to meet tight tolerances. While most designs end up in engineering and computer-aided design, many designs begin with hand-drawn sketches in the initial stages.
