Figure 1.43 Approximation error
CNC machining error â–³ number is caused by programming error â–³, machine error â–³ machine, positioning error â–³ set, knife error â–³ knife and other errors formed. That is: â–³ number plus = f (â–³ â–³ + + machine + â–³ set + â–³ knife)among them:
(1) The programming error △ consists of approximation error δ and rounding error. The approximation error δ is generated during the process of approximating a non-circular curve with a straight segment or an arc segment, as shown in Figure 1.43. The rounding error is an error generated by rounding off the coordinate values ​​to integer pulse equivalent values ​​during data processing. Pulse equivalent refers to the displacement of the corresponding axis for each unit pulse. Ordinary precision CNC machine tools, the general pulse equivalent value is 0.01mm; more accurate CNC machine tool pulse equivalent value is 0.005mm or 0.001mm.
(2) The machine tool error â–³ machine is caused by the numerical control system error, feed system error and other reasons.
(3) Positioning error â–³ is determined when the workpiece is positioned on the fixture and the fixture is positioned on the machine.
(4) Tool setting error The tool is generated when the relative position between the tool and the workpiece is determined.
