电火花线切割概述（Overview of WEDM） Documents from the network, I collected, finishing, and if there are omissions, errors, but also please correct me! Objective and requirement of NC wire cutting practice; 1. Grasp the machining principle, characteristics and application range of wire cutting 2. Understand the system composition and functions of WEDM machine tools 3, master the linear cutting machine programming methods, at least master a method, skilled in the preparation of general procedures 4. Master the operation method of WEDM machine tools 5. Understand the automatic programming method of WEDM machine tools 6. Understand the routine maintenance and basic troubleshooting of WEDM machine tools Overview of WEDM The electrode wire EDM wire (molybdenum wire, tungsten molybdenum wire etc.) as the tool electrode, in pulsed power supply under the effect of spark discharge formed between the tool electrode and the workpiece, the spark channel instantly generate a lot of heat, the surface melting and vaporization, electric fire cutting machine through the X-Y thread carriage movement, the the wire electrode along a prescribed trajectory, so as to achieve the purpose of workpiece This paper takes BKDC as an example Machine specification: Control shaft number: X, Y, U, V four axis linkage control Minimum setting: 0.001mm Minimum mobile unit: 0.001mm Input mode: serial input, disk input, keyboard input Code mode: ISO, 3B, DXF code Instruction mode: increment value, absolute value Instruction unit: metric, British Backlash compensation: X, Y, U, V, four axis, 0~127 mu m Line diameter compensation: 0~9.999mm Processing methods: file mode CMD, ISO, 3B, DXF files can be converted to ISO files Automatic alignment and automatic alignment of the center of the hole Automatic back vertical Cutting direction: forward or reverse Graphic display: the upper plane, the lower plane, the wire rack, the upper plane, the lower plane figure, the coefficient of arbitrary choice Processing status dis
