CNC machined parts are parts manufactured through computer numerical control (CNC) technology. And it has been widely applied in various industries, such as aerospace, automotive, shipbuilding, medical and other fields. So, let's understand that measurement errors in CNC machined parts may be affected by various factors. Here are some of the main factors: × 9312;Machine tool errors: spindle rotation errors: This includes coaxiality errors in several sections of the spindle neck, various errors in the bearings themselves, coaxiality errors between bearings, and spindle deflection. Guidrail error: The guide rail is the benchmark for determining the relative position relationship of various parts of the machine tool, and its uneven wear and installation quality can also lead to errors. Error transmissionis chaini: Errores manufacturae et congregationis variorum componentum in catena transmissionis, etiam porta et lacrima in usu potest causare errores transmissionis Error instrumenti: Instrumentum inevitabilem extinguit dum procedura succidit, tunc magnitudinem et formam opus mutat. The design, manufacturing, and grinding errors of cutting tools will have a direct impact on the machining results Error fixturae: Functio fixturae est facere opus ex instrumento equivalentem et instrumentum machinae in positio recto tenere. The geometric errors of fixtures have a significant impact on machining errors, especially positional errors Positioning error: This mainly includes baseline mislignment and inaccurate positioning error Error caused by deformation of the process system: Workpiece stiffness: If the stiffness of the work piece is relatively low compared to the machine tool, tool, and fixture, the deformation caused by insufficient stiffness under the action of cutting force will affect the machining accuracy of the work piece. Tool rigidity: The rigidity of the tool can also affect machining accuracy. The stiffness of machine tools components: Machine tools components are composed of many parts, and their stiffness also affects machining accuracy Errores due to thermal deformation in the process system: Thermal deformation is another important factor that leads to machining errors Labpiece material error: The material of mechanical parts may have defects or unevenness during the manufacturing process, such as internal stress, incomplete melting, etc., which can have a negative impact on the processing results Error measurement: CNC Machining centers are mainly affected by the measurement accuracy of measuring tools and the operating methods of the operator, resulting in inaccurate measured dimensions Error Alimentationis: dum procedura Alimentationis, instrumentum CNC machinationis centrum influentur a valore alimentationis alimentationis alimentationis systemae operationis quando movetur ad positionem initii, quod etiam errores potest causare. To reduce these errors, a series of measures can be taken, such as improving machine tool accuracy, optimizing tool design, improving fixture design, precise positioning, enhancing process system stiffness, controlling thermal deformation, optimizing workpiece material selection, improving measurement accuracy, and precise control of the cutting process.
