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]
In 2003, Makino developed the first conventional horizontal wire EDM that automatically threads and machines with a 0.02mm diameter wire. [6] In 2006, the company developed High Energy Applied Technology (HEAT) for wire EDMs to increase speed in wire EDMing, [6] and released the EDAC1 micro EDM ram machine. Makino is also the only manufacturer ...
Electrical discharge machining (or EDM) is one of the most accurate manufacturing processes available for creating complex or simple shapes and geometries within parts and assemblies. A machining method typically used for hard metals, EDM makes it possible to work with metals for which traditional machining techniques are ineffective.
WorkNC Wire EDM is a CAD/CAM software for Wire Electrical discharge machining. Dialog boxes guide the user through the system. Functions within WorkNC Wire EDM allow the extraction of cross sections, ready for 2- or 4-axis cutting. Alternatively, the 3D surfaces of the CAD model can be used directly.
Or, if there are 5 operations at 1.5 hours each, but only 30 minutes total machine time, then 7.5 hours is charged for just 30 minutes of machining. [3] Lastly, the volume (number of parts to machine) plays a critical role in amortizing the set-up time, programming time and other activities into the cost of the part.
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]
The vertical machine consists of a base, column, table, and spindle head. The spindle head has a servo-mechanism that automatically advances the tool and controls the gap between the cathode (tool) and the workpiece. [1] CNC machines of up to six axes are available. [2] Copper is often used as the electrode material.
Today's CAM systems support the full range of machine tools including: turning, 5 axis machining, waterjet, laser / plasma cutting, and wire EDM. Today’s CAM user can easily generate streamlined tool paths, optimized tool axis tilt for higher feed rates, better tool life and surface finish, and ideal cutting depth.
