Performance Horizontal Roughing was important to be done prior to the 3-axis Projection Pocketing in order to save time. The whole process in total took 1 hour. 3D milling – Process consisted of two phases: First phase: horizontal roughing Tool: BallMill 26mm in diameter Dimensions of the board: 600 by 400mm Boards of 8mm thickness Time taken: 9 min. Second phase: Projection Pocketing following a rectangular path Tool: Ballmill 12mm in diameter Global parameters intol: 0 , outtol: 0.4, % Tool Diameter: 25 % Time taken: 48 minutes
