AUTOMATIC MACHINE TOOLS
Automatic machine tools are not new, but they have increased in numbers and types at a great rate since the
end of World War II. At the same time a new word, automation became a new technical term. Automation has
many interpretations, but briefly it means taking most of the handwork and skill away from the machine opera-
tor and often eliminating him altogether by utilizing hopper feeds and automatic measuring devices.
All operations in machining a workpiece on a metal-cutting machine tool are classified as either processing
or handling operations. Processing operations are those in which the actual cutting process or chip removal
takes place. The rest are handling operations. They include loading and clamping the work, advancing with-
drawing the cutting tools, releasing and unloading the work, checking the size of the workpiece, etc.
Machine tools designs with mechanisms that perform the majority of the required handling operations
without the direct participation of the operator are called automatic machine tools.
Highly automatic machine tools are ordinarily classified as automatics and semi-automatics.
Automatics, as their name implies, are machine tools which machine workpieses automatically. They have
a fully automatic working cycle repeated to produce duplicate parts without participation of the operator. All of
the working and handling operations are performed in a definite sequence by the control system adopted in the
automatic, which must be set up to suit the given job.
Semi-automatics are machine tools in which the actual machining operations are performed automatically
in the same manner as on automatics. In this case, however, the operator loads the blank into the machine, starts
the machine, checks the work size, and removes the completed piece by hand. The machining cycle is auto-
matic, but direct participation of the operator is required to start each subsequent cycle, i. e. to machine each
subsequent workpiece.
II. Translate the summary of the text into English.
Данный текст посвящен описанию автоматических инструментов. Термин «автоматизация» появил-
ся в техническом мире недавно. Данный термин имеет несколько значений. Самое распространенное
значение данного понятия – это замена ручного труда на производстве машинным. Автор говорит о том,
что станки снабжены механизмами, которые выполняют необходимые операции без участия оператора.
Такие станки называются станками-автоматами. Станки могут быть полностью автоматизированы. Неко-
торые станки являются полуавтоматами. Станки – автоматы имеют полностью автоматический рабочий
цикл. Вся работа выполняется в строгой последовательности и контролируется системой управления.
Текст заканчивается информацией о полуавтоматах.
