Рассмотрены вопросы повышения точности при обработке на станках с ЧПУ, а именно: оценка степени влияния погрешностей геометрической формы инструментальных оправок на точность осевого расположения и угловую жесткость при закреплении в шпинделе станка.
The problems of accuracy improvement at billet processing withemphasison the influence degree of errors in tool holder geometric forms on the accuracy of the in-line arrangement and tangent stiffness atfixing in a machine spindle are considered. The most frequent cases of form errors, occurring at the tool holders production, are considered: circular deviation (particularly occurrence of out-of-roundness in cross-sectional view), deviations of straightness of cone generatrix (bulge, incurvature), angular errors. To evaluate the accuracy of the in-line arrangement and rigidity of corners of the tool spindle intersystem, the ANSYS Software is used.
