Description: During the last step EasyWOOD calculates automatically machining time, length and costs. 3D simulation of the machining process, idling included, is realistic because it shows the 3D model of the machining centre, of the table, tools, motors, sub-pieces and of the workpiece. Furthermore EasyWOOD allows 3D collision detection between machinings and pieces, subpieces and tools. The automatic collision detection module reduces testing, ensures less material and power consumption and consequently respects the environment. In the end EasyWOOD generates part programs and send them directly to the NC centre of the Customer.
