Nineteenth century, the best mechanic should count Whitworth (full Mingyuesefu · Whitworth), he made a measuring machine in 1834, the measuring machine can measure the length of the error millionths of an inch about. The principle of this measuring machine and micrometer same multi-axis drilling, by rotating the indexing plate can be out of the thread clamped workpieces, using slider indexing indexing readout board. In 1835, Whitworth invention hobbing in his 32 years of age. In addition, Whitworth also designed the inner circle and outer circle measuring cylinder plug and ring gauges. All the recommendations of machine tool production industry have adopted the same standard thread sizes. Later, multi-axis drilling manufacturers, British Standards Institute to develop industry accepted this proposal, and since then until today, such as a standard threaded screw is used by various countries. 1950 period after World War II into the automation, due to the NC and group control machine tools and automatic lines, the development of the machine began to enter the era of automation. CNC machine tools are computer after the invention, the use of digital control theory, the processing procedures, requirements, and tool change operation code as digital and text information storage, in accordance with its instructions issued by the control machine tools, according to the established requirements for processing The new machines. The world's first CNC machine tools (milling) was born (1951) CNC multi-axis CNC machine tools drilling program, the United States Parsons (full name John Parsons) in the development of inspection aircraft propeller blade section outlines board leaf processing When presented to the US Air Force aircraft, with the participation and assistance of MIT, and finally succeeded in 1949. 1951 multi-axis drilling price, they officially made the first prototype tube CNC machine tools, automation successfully solved the problem of complex parts of many varieties of small batch processing. Later, on the one hand from the CNC milling machine to extend the principles of milling and boring machines, drilling machines and lathes, on the other hand, the transition from tubes to transistors, integrated circuits direction. In 1958, the United States developed into automatic tool change to multi-step process of machining centers.
