Design Of Open CNC With Flame Cutting Based On Motion Controller

In China’s CNC machine tool industry, CNC flame cutting as a commonly used cuttingequipment for cutting, domestic enterprises in great demand. Since the presence of NC systemis not yet fully independent development, and system closed other reasons. Current CNCflame cutting machines generally expensive and difficult to upgrade the system. So the facefor many small and medium enterprises, to design a reliable economical CNC flame cuttingmachine has a large market demand.Combined CNC flame machining principle and processing Factors influencing accuracyof the work piece as a reference to design a motion control card based on Open CNC flamecutting machines. First, through the analysis and workpiece machining principle factorsaffecting the quality, mading flame cutting machine design requirements. Then the designrequirements for CNC flame cutting machines, made general scheme of the system, and thecorresponding control strategy, namely IPC+motion control card of the open-loop mode. Webuild a control strategy based control system and select the appropriate hardware. CNCsystem itself is an open system, CNC flame cutting machine CNC servo drive part can becombined as a test platform for a variety of CNC control experiments.According to transmission design, select screw nut, coupling drive feed. Select gantrystructure as the flame cutting machine frame structure, gear selection and calculation testscarried out, and the main transmission parts to choose checked. Mainly on the sliding screwand rolling screw strength and transmission efficiency was calculated checked. Proposed andimplemented stepper motor control, the motor chosen and made a calculation check. Test toverify this through the transmission control method has a good feasibility. Finally, CNC flamecutting machines and sources of error are analyzed, and through error compensation methodto improve CNC flame cutting machine precision..
