The drill Nc milling machining technology: the drilling milling circuit CNC drilling machine technology including the choose to walk knife direction, pensation methods, positioning method, frame structure, the knife point. Are guaranteed the important aspect of milling machining accuracy. 1, go knife direction, pensation methods: When milling cutters cut by board, a block of the milling cutter face always, and cutting edge against a side of the milling cutter is cutting edge. The former, processed surface is bright and clean, dimension precision is high. Spindle always clockwise. So either spindle fixing bench sport or workbench fixed spindle movement of the CNC milling machine, PCB external outline in milling, must use the anticlockwise direction when walking knife. This is usually said inverse milling. And in PCB internal milling box or groove along the way used when milling. Milling board pensation is when the milling machine according to be automatic Ann plate cutter with value to the center of the circuit automatically milling cutter diameter set by the migration of the half, namely radius distance, make the appearance of the milling consistent with program. While such as tool has the function of pensation for pensation of necessary notice direction and procedures used to mand, such as the use of pensation mand errors will make PCB appearance more or less equivalent length and width of milling cutter diameter size. 2, positioning method and the knife point: Positioning method can be divided into two。 One is the second is in the position, orientation. Positioning for technology formulating workers also very important at the board preproduction, usually when the positioning of the scheme should be determined. Position is the general method within. Socalled localization is choose within the mounting holes in the PCB, plug the holes or other nonmetal to dial as positioning hole hole. Hole in the relative position as possible to choose on the diagonal of large diameter and holes. Cannot use metallization holes. Because hole plating thickness differences influence you selected a hole in the coherence, but also take the board is very easy to create the hole and pore surface coating damage, in the edge of PCB under the condition of guaranteed orientation, pin number less as possible. General small plate use 2 pieces pin, the big board, use 3 pieces pin, its advantage is accurate positioning, board shape distortion high precision milling speed, good appearance. Its defect board inside various aperture to prepare various types, such as the diameter of 南通職業(yè)大學(xué)畢業(yè)設(shè)計(jì)（論文） 45 the pin in the plate there is no available positioning hole, in the early production with customers in need when the board to discuss with positioning hole is, relatively troublesome. Meanwhile each kind of plate mill plate template different management more trouble, higher cost. The location is another kind of locating method, is adopted in board external add positioning hole as milling plate localization holes. Its advantage is manageable, if prior regulated production well, milling board in monly fifteen or template. By using the positioning so can39。t once milling down, or PCB board is easy damage, especially makeup, for milling cutters and vacuuming device will bring out circuit boards caused damage and milling cutters broken. And by subsection, the method of bining t
