Understanding dental CAD/CAM for restorations - dental Milling Machines from a mechanical engineering viewpoint. Part A: chairside Milling Machines.
International journal of computerized dentistry, 2016Co-Authors: Nicolas Lebon, Laurent Tapie, Francois Duret, Jean-pierre AttalAbstract:Nowadays, dental numerical controlled (NC) Milling Machines are available for dental laboratories (labside solution) and dental production centers. This article provides a mechanical engineering approach to NC Milling Machines to help dental technicians understand the involvement of technology in digital dentistry practice. The technical and economic criteria are described for four labside and two production center dental NC Milling Machines available on the market. The technical criteria are focused on the capacities of the embedded technologies of Milling Machines to mill prosthetic materials and various restoration shapes. The economic criteria are focused on investment cost and interoperability with third-party software. The clinical relevance of the technology is discussed through the accuracy and integrity of the restoration. It can be asserted that dental production center Milling Machines offer a wider range of materials and types of restoration shapes than labside solutions, while labside solutions offer a wider range than chairside solutions. The accuracy and integrity of restorations may be improved as a function of the embedded technologies provided. However, the more complex the technical solutions available, the more skilled the user must be. Investment cost and interoperability with third-party software increase according to the quality of the embedded technologies implemented. Each private dental practice may decide which fabrication option to use depending on the scope of the practice.

theoretical experimental modeling of Milling Machines for the prediction of chatter vibration
International Journal of Machine Tools & Manufacture, 2011Co-Authors: Giuseppe Catania, Nicolò MancinelliAbstract:Abstract Productivity of high speed Milling operations can be seriously limited by chatter occurrence. Chatter vibrations can imprint a poor surface finish on the workpiece and can damage the cutting tool and the machine. Chatter occurrence is strongly affected by the dynamic response of the whole system, i.e. the Milling machine, the tool holder, the tool, the workpiece and the workpiece clamping fixture. Tool changes must be taken into account in order to properly predict chatter occurrence. In this study, a model of the Milling machine–tool is proposed: the machine frame and the spindle were modeled by an experimentally evaluated modal model, while the tool was modeled by a discrete modal approach, based on the continuous beam shape analytical eigenfunctions. A chatter identification technique, based on this analytical–experimental model, was implemented. Tool changes can be easily taken into account without requiring any experimental tests. A 4 axis numerically controlled (NC) Milling machine was instrumented in order to identify and validate the proposed model. The Milling machine model was excited by regenerative, time-varying cutting forces, leading to a set of Delay Differential Equations (DDEs) with periodic coefficients. The stability lobe charts were evaluated using the semi-discretization method that was extended to n >2 degrees of freedom (dof) models. The stability predictions obtained by the analytical model are compared to the results of several cutting tests accomplished on the instrumented NC Milling machine.
