The lathe is one of the oldest manufacturing technologies on Earth; in fact, its earliest version dates back to the Egyptians around BC. The technology has exponentially increased, become more and more advanced every decade, and today, lathes are used to create everything from artisan wooden bowls to large parts for heavy machinery. Lathe: Lathes are machines that shape material by rotating a drive, which turns the piece being worked on against cutting tools that can be switched out to obtain the appropriate cut. Tool: The tooling is the cutting mechanism affixed to the machine to build parts. Headstock: The headstock holds the workpiece, provides power to various parts of the machine, and rotates the spindle. Carriage: The carriage supports the cutting tool, guiding and feeding it against the workpiece. Although they might look alike, horizontal CNC turning centers are an evolutionary leap from the CNC lathe machines of the past.

The term CNC stands for 'computer numerical control', and the CNC machining definition is that it is a subtractive manufacturing process which typically employs computerized controls and machine tools to remove layers of material from a stock piece—known as the blank or workpiece—and produces a custom-designed part. This process is suitable for a wide range of materials, including metals, plastics , wood, glass , foam, and composites, and finds application in a variety of industries, such as large CNC machining and CNC machining aerospace parts. Note there is a difference between the CNC machining definition and the CNC machine definition- one is a process and the other is a machine.

Skip to Main Content. A not-for-profit organization, IEEE is the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity. Use of this web site signifies your agreement to the terms and conditions. The prototype can handle the machining of parts with relative complexity, i. The implementation process started from the structure of a manual parallel lathe, which was redesigned in order to increase the degrees of freedom and turn it into a 4-axis milling lathe. Each axis contains a ballscrew activated by a servomotor and controlled by a servodriv. Velocity- and position-related movement is programmed using specific software which is able to interpret geometric code G-code generated by CAM, as the result of a CAD design, for the computer-aided machining of parts, establishing a HMI.

Use the keyboard up, down, left and right to move spindle to the machining origin of the workpiece, then use Page Up and Page Down keys to move the Z-axis down to contact the machining surface.

The history of numerical control NC began when the automation of machine tools first incorporated concepts of abstractly programmable logic, and it continues today with the ongoing evolution of computer numerical control CNC technology.

A turret shown center , with tooling attached is programmed to move to the bar of raw material and remove material to create the programmed result. If the center has both tuning and milling capabilities, such as the one above, the rotation can be stopped to allow for milling out of other shapes. Request Your Quote. While a lot of factors go into determining if a part can be made most cost-effectively on a specific CNC turning center, some things we look at are:.

Когда он проволок ее по ковру, с ее ног соскочили туфли. Затем он одним движением швырнул ее на пол возле своего терминала. Сьюзан упала на спину, юбка ее задралась. Верхняя пуговица блузки расстегнулась, и в синеватом свете экрана было видно, как тяжело вздымается ее грудь. Она в ужасе смотрела, как он придавливает ее к полу, стараясь разобрать выражение его глаз.

 Сколько в тебе снобизма.  - Хейл вздохнул и повернулся к своему компьютеру. В этом вся ее сущность. Блестящий криптограф - и давнишнее разочарование Хейла. Он часто представлял, как занимается с ней сексом: прижимает ее к овальной поверхности ТРАНСТЕКСТА и берет прямо там, на теплом кафеле черного пола.

Росио улыбнулась: - Todo bajo el sol. Чего только нет под солнцем. - Это был девиз туристского бюро Севильи.

Его редеющие седые волосы спутались, и даже несмотря на прохладу, создаваемую мощным кондиционером, на лбу у него выступили капельки пота. Его костюм выглядел так, будто он в нем спал. Стратмор сидел за современным письменным столом с двумя клавиатурами и монитором в расположенной сбоку нише. Стол был завален компьютерными распечатками и выглядел каким-то чужеродным в этом задернутом шторами помещении. - Тяжелая неделя? - спросила .

Вина ляжет на АНБ. - Мы успеем найти его партнера. - Думаю.

 - Сколько будет сто десять минус тридцать пять и две десятых. - Семьдесят четыре и восемь десятых, - сказала Сьюзан.  - Но я не думаю… - С дороги! - закричал Джабба, рванувшись к клавиатуре монитора.

Пол был уставлен десятками больничных коек. В дальнем углу, прямо под табло, которое когда-то показывало счет проходивших здесь матчей, он увидел слегка покосившуюся телефонную будку. Дай Бог, чтобы телефон работал, мысленно взмолился Беккер.
