“…The spindle-SVDH-tool finite element model is restricted to the rotating system composed of the spindle shaft, the SVDH and the drill. An experimental modal identification procedure was carried out on the different spindle substructures and showed that spindle behaviour can be restricted to rotating structure behaviour [12]. The interfaces represented by the HSK63 taper, spring and ball retainer, and collet chuck were taken into account in the model.…”

“…Such rotating systems have been successfully modelled through rotor-dynamics studies [10,11]. In previous works [12,13], a dynamic high-speed spindle-bearing system model based on rotor dynamics prediction was presented. Element kinematics were formulated in a corotational coordinate frame and enabled a special rotor beam element to be developed.…”

The machining of deep holes is limited due to inadequate chip evacuation, which induces tool breakage. To limit this drawback, retreat cycles and lubrication are used. An alternative response to the evacuation problem is based on high-speed vibratory drilling. A specific tool holder induces axial self-maintained vibration of the drill, which enables the chips to be split. The chips are thus of a small size and can be evacuated. To anticipate the potential risk of decreased spindle lifespan associated with these vibrations, a model of the behavior of the system (spindle-self-vibrating drilling head-tool) is elaborated. In order to assess the dynamic behavior of the system, this study develops a rotor-based finite element model, integrated with the modelling of component interfaces. The current results indicate that the simulations are consistent with the experimental measurements. The influence of spindle speed and feed rate on bearing lifespan is highlighted.

“…Prediction of frequency response at the tool tip is of paramount importance in assessing the machining quality at the design stage. Gagnola et al [1] formulated a dynamic model of a high-speed spindle-bearing system and it is elaborated on the basis of rotor dynamics predictions and readjusted with respect to experimental modal identification. Further, the stability limits calculated from the rotating FRF which is significantly higher due to the increased dynamic stiffness.…”

Abstract-Present work aims at designing the manual vertical milling machine tool from the available variable speed drilling machine in the workshop. To this end, a realistic spindle tool unit of manual drilling machine is first considered and its modal characteristics are arrived experimentally. While, using the drilling machine in a moving x-y plane as in milling operations, the topology of spindle unit is slightly modified relatively to the existing drill tool spindle in order to minimize the chattering during machining in normal conditions,. The tool tip frequency response and stability lobe diagrams are obtained for different topologies using finite element method. The optimized topology of spindle unit is selected and its solid model is prepared in solidworks (R) . While the Z-motion is designed in above stages, the X and Y table movements are provided with a carefully designed bed unit actuated by ball-screw mechanisms.

ARTICLE INFO ABSTRACT Article history:This paper proposes a method to predict chatter vibration generated in milling processes and to enhance machining quality and surface finish. Chatter vibration is a common problem in the milling of thin walls and floors. It causes a poor surface finish, or even marks, to appear on the final machined surface. Therefore, an effective method is necessary to predict chatter vibration in machine tools. In this investigation, chatter vibration is measured by an accelerometer, microphone, and Acoustic Emission (AE) sensor in a machining operation. Based on the results of the experiment, a microphone can be applied for the prediction of chatter vibration in milling processes. . 채터진동의 발생 은 공작물 표면상의 나타나는 채터무늬나 특유의 소음, 진동 그리 고 절삭력의 변화 등으로 판단할 수 있다 [3] .
