A wire-cut EDM machine using the CNC drawing plotter and optical line follower techniques was produced in 1974. Dulebohn later used the same plotter CNC program to directly control the EDM machine, and the first CNC EDM machine was produced in 1976. [10] Commercial wire EDM capability and use has advanced substantially during recent decades. [11]
CNC routers can perform the tasks of many carpentry shop machines such as the panel saw, the spindle moulder, and the boring machine. They can also cut joinery such as mortises and tenons. A CNC router is very similar in concept to a CNC milling machine. Instead of routing by hand, tool paths are controlled via computer numerical control.
A CNC machine that operates on wood CNC machines typically use some kind of coolant, typically a water-miscible oil, to keep the tool and parts from getting hot. A CNC metal lathe with the door open. In machining, numerical control, also called computer numerical control (CNC), [1] is the automated control of tools by means of a computer. [2]
Genertec was founded in the 1950s as part of the First Five Year Plan (1953–1957) to break ground within China in machinery manufacturing. Some of the key products in its machinery business include "heavy-duty CNC milling-boring machines, heavy-duty mechanical presses, large automatic metal forming machines and a series of milling machines."

As with other machine tools, CNC (computer numerical control) technology was applied to plasma cutting machines in the late 1980s into the 1990s, giving plasma cutting machines greater flexibility to cut diverse shapes "on demand" based on a set of instructions that were programmed into the machine's numerical control. [2] These CNC plasma ...
The wire goes in the one near the edge, and the post is inserted into the hole in the center. Automated wire-wrap machines, as manufactured by the Gardner Denver Company in the 1960s and 1970s, were capable of automatically routing, cutting, stripping and wrapping wires onto an electronic "backplane" or "circuit board".
Apple's smartphone shipments in China were 52% higher in April than a year ago, extending a rebound seen in the previous month, according to data from a research firm affiliated the Chinese ...
The introduction of lower-cost CNC machines radically changed the manufacturing industry. Curves are as easy to cut as straight lines, complex 3-D structures are relatively easy to produce, and the number of machining steps that required human action have been dramatically reduced.
