Cnc machinery factory in Dongguan of Chinas machinery enterprises still need to observe the actual demand recovery

    1. CNC lathe cutter compensation
    CNC lathe tool compensation function including tool position compensation and arc radius compensation from two aspects.T function is specified, in processing procedures used TXXXX first two XX for cutting tools, after two XX for cutting tool compensation, such as T0202.If the cutter compensation of 00, cancel the knife repairing.
    (1) tool position compensation tool wear or reinstall tool cutter location changes, large CNC machinery factory, dongguan boring processing factory in guangzhou, shenzhen large frame welding, grinding mills, large gantry milling machine, large CNC gantry milling machine, large computer gong mechanical processing plants, boring mills, q345 seamless tube factory, q235 steel factory, aluminum and magnesium, manganese plate processing, a3 cold plate, 45 # steel processing machinery factory, dongguan machinery, dongguan machinery factory set up, the tool position compensation, after processing program, it does not need to be compiled again.Method is to measure each of the cutting tool and the input to the specified storage location, program execution tool compensation command, the actual location of the cutter is instead of the original position.
    If there is no tool compensation, tool point move from 0 to 1, the corresponding procedures section is N60G00C45X93T0200, if the cutter compensation is X = + 3, + 4 Z =, storage, and deposited in the corresponding compensation after execution of knife repairing, cutting tool move from 0 to 2 points, rather than 1 point, the corresponding procedures section is N60G00X45Z93T0202.
    Cutting tool arc radius compensation (2) CNC lathe processing program, the tool tip is considered to be an imaginary point P (point), but in fact, in order to improve the tool life and reduce the surface roughness of workpiece and tool tip be ground into small radius arc (point AB arc), as shown in figure 3, it will have the shape of the machining error.Tip arc, on the other hand, the location, shape of cutting tool to the workpiece machining will also impact, and the cutting tool arc radius compensation can be used to solve.Shape and the location of the cutting tool parameter called point location, as shown in figure 4, expressed with parameter 0 ~ 9, P points for theoretical point.
    (3) the knife repairing parameters of each cutter compensation number corresponding to the cutting tool position compensation (X and Z value) mechanical processing factory, dongguan large CNC machinery processing plants, boring processing factory in guangzhou, shenzhen large frame welding, grinding mills, large gantry milling machine, large CNC gantry milling machine, large computer gong mechanical processing plants, boring mills, q345 seamless tube factory, q235 steel factory, aluminum and magnesium, manganese plate processing, a3 cold plate, 45 # steel processing machinery, dongguan dongguan machinery factory and knives circular arc radius compensation (R and T value), a total of four parameters, the input to the corresponding memory before processing, displayed on the CRT is shown in figure 5.In the process of automatic, CNC system according to the memory of the value of X, Z, R, T, automatic correction tool position error and automatically tip arc radius compensation.
    2. Processing center, CNC milling machine tool compensation
    Processing center, CNC milling machine, CNC system, cutting tool compensation function including the cutting tool radius compensation, the cutting tool compensation function such as Angle compensation and length compensation.(1) the cutting tool radius compensation (G41, G42, G40) cutter radius value in advance in the memory HXX, XX number for storage.After the tool radius compensation, CNC automatic calculation system, and makes the tool automatic compensation according to the calculation results.Tool radius compensation (G41) refers to the left towards the programming process track movement direction of the left (as shown in figure 1), the cutting tool radius compensation (G42) refers to the right tool to programming process track to the right direction.Cancellation of tool radius compensation in G40, cancellation of tool radius compensation H00 is also available.
    Use note: to establish a stoppage time, cancel the knife, which USES G41, G42, G40 instructions procedures section must be using G00 or G01, shall not use G02 or G03, when negative cutting tool radius compensation, G41 and G42 function.
    Have the functions of B and C tool radius compensation two forms of compensation.Because B function cutter radius compensation according to the procedures in this section is only knife repairing has been done, and can't solve the problem of the transition between the procedures section, request the workpiece contour processing into a rounded transition, therefore the workpiece Angle of manufacturability is bad, C function cutter radius compensation can automatic processing the two transfer procedures section cutting tool center orbit, can be completely according to the workpiece contour to programming, so almost all modern CNC numerical control machine adopts C function cutter radius compensation.Then their quest to establish a tool radius compensation program period of follow-up two paragraph must have specified compensation plane displacement instructions (G00, G01, G02, G03), otherwise unable to establish the correct tool compensation.
