Abstract:

Дискові відрізні фрези є інструментом, який працює у найбільш складних, з точки зору динамічного стану в процесі відрізки заготовок, умовах. Дискові відрізні фрези працюють в умовах скованого різання, пов'язаного зі складністю відведення стружки та тепла із зони різання, тому процес відрізання дисковими фрезами супроводжується великою кількістю фізико-хімічних явищ. До них відносяться явища, пов'язані із пластичним деформуванням і руйнуванням металу в процесі зняття стружки, з тепловими явищами, електромагнітними, хімічними, динамічними та іншими явищами. Ці явища взаємозалежні між собою та вп

Abstract:

Secondary hardwood products manufacturers have been placing heavy emphasis on lumber yield improvements in recent years. More attention has been on lumber grade and cutting technology rather than cutting bill design. However, understanding the underlying physical phenomena of cutting bill requirements and yield is essential to improve lumber yield in rough mills. This understanding could also be helpful in constructing a novel lumber yield estimation model. The purpose of this study was to advance the understanding of the phenomena relating cutting bill requirements and yield. The scientific

Since aircrafts manufacturers intend to produce low consumption and efficient aircrafts, parts become more and more difficult to machine. Some processes like „air machining“ enables a one-step production for complex aluminium alloy shaped parts. Although the assembly offers a large access to cutting tool, the lack of stiffness for large parts, and especially for thin-walled aeronautics parts implies strong vibrations during machining. The aim of the study is to solve these difficulties in order to keep productivity and improve surface quality. Further innovative solutions are considered like m

The dimensional accuracy of cutting tools and the status of ground cutting edge considerably influence the processing precision of workpieces. However, inspection of the flatness of cutting edges are mainly conducted through manual measurement using microscopes or unaided eyes. Conventional manual inspection is often under the constraints of the inspectors’ physical conditions such as visual acuity and stamina, leadin
