Method for machining curvilinear surfaces at the constant Vc and Vf milling parameters

摘要

the characteristic feature of milling surface krzywoliniowych variability is cross-sectional layer skrawanej.this property is related to the complex movements tools with respect to the work surface.change the size of skrawanej layers are linked to changes of the angle of contact. how to change the angle and tools to the treatment.the variability of field layer skrawanej affects physical phenomena occurring during the process of removing (strength, vibration) and technological parameters (roughness, the deviations of the shape).the essence of the patent is that milling parameters vc and vf during surface treatment krzywoliniowych are fixed. it is related to using a suitable strategy in cad / cam systems.on the basis of the angle of inclination, the work surface. and depth of milling ap determined diameter effective def.when the cross section of skrawnej is variable changes also diameter effective def and thus removing speed vc.therefore, the blade relative to the work surface is generated on the work surface and the spatial model on the basis of selected is variable speed cutting.in a similar manner selected is variable speed motion posuwowego vf.on the basis of the radius of curvature and the diameter of the frezu dfr work outline rp determined actual velocity posuwowego vf.the proposed method is characterized by constant change both speed n (in order to ensure a constant speed vc), as well as posuwowego velocity so that the value of vfks = const.innovation method is using path generated by the cam tool to determine the kinematic parameters.
