CNC machines are a type of lathe designed to facilitate and automate agricultural or other manpower-requiring jobs. CNC (Computer Numerical Control) stands for computerized numerical control. These devices are a workbench needed in the machinery, agriculture and automotive sectors. CNC machines operate in every field today in order to increase speed and professionalism in jobs that require manpower.
The idea of numerical control was first put forward after the Second World War for the cutting of complex parts in the aircraft production of the United States. Because it was very difficult to produce the mentioned parts by processing on the cutting benches of that period. PARSONS COMPANY and MIT collaborated to design the first CNC machine. As a result of these studies, the first CNC machine, CINCINNATTI – HYDROTEL, went down in history as a milling machine. The first CNC machines used vacuum tubes or electrical relays. However, when these equipments started to fail frequently, the replacement costs increased and it was necessary to turn to other techniques. For this reason, small electronic tubes and circuits in one piece began to be used in CNC machines. Today, these electronic circuits continue to be developed and used. With ROM (Read Only Memory, Read – Store) technology, CNC machines now make it possible to store programs in memory.
The basic working logic of CNC machines is based on the operation of human language by converting it into machine language through commands coded with numbers, letters and similar symbols. In CNC machines, it is possible to stop a command loaded to the control unit at any step of the process. It is even possible to stop the work of a working CNC machine, change it and resume it. Uploading the commands written in the computer environment to the CNC machines can be done with very different methods depending on the brand and model of the device.
Examples of CNC machines are lathe, milling machine, drill machine, boring machine, and grinding machine. All these machines have their own unique capacities, memories and processing speeds.
CNC machines have many advantages over other non-automatic machines that do the same job. Since the adjustment settings of CNC machines are very sensitive, the most detailed operations can be done with high precision. Since the human factor is largely eliminated, rapid and effective work can be achieved. We hope in this article What is CNC? You couldn’t answer the question.
