Teaching type CNC engraving machine overall design of the experimental system
Teaching type CNC engraving machine experiment system based on PC for mechanical professional students practise CNC programming, machining small mould; Electrical professional students of print circuit board; Fine arts students in making hand calligraphed, relief. 。 。 。 。 。 The overall scheme is as follows: 1. Overall structure column fixed, engraving head make lateral and move up and down, table for the longitudinal direction. The structure, easy manufacturing, low cost, good stability, able to adapt to the sculpture of soft metal and non-metal materials. 2. Engraving and milling machine adopted in moving parts > motorized spindle to achieve the main movement; Feed movement of the transmission adopts the ball screw pair, step motor through the coupling and the ball screw pair connection. 3. Numerical control system the main movement adopts frequency converter speed control open-loop control, feed movement driven by step motor open loop control. “ Cut & throughout; &ldquo仍然; Time & throughout; For two coordinates linkage control, & other; Carving & throughout; Relief for the three coordinate control two coordinates linkage, use & other; Line cutting & throughout; Processing. Using software CNC, with the aid of existing Windows platform, with the support of engraving software, control system for the main motion and feed motion.
