Implant denture is the most essential method of oral repair, and its processing depends heavily on the precision machining center. Most special denture machine tools do not take into account the requirement of automatic machining of parts. During processing, the parts need to be double-clamped, which changes the geometry of the parts. In this paper, a small special machine tool with seven axes has been developed to realize the automatic processing of implant dentures. Firstly, the processing technology of implant dentures is introduced, and the function of a special machine tool is analyzed. Then, the mechanical structure of the machine tool is established. It has seven moving axes and two cylinders, with the capability of five-axis linkage and combined turning and milling. Uniquely, it has a backside machining unit, which allows the entire automated machining process to be completed after only one clamping. The topological movement chain of the machine tool under different working modes is introduced emphatically. The results show that the machine structure can satisfy the automatic machining process of denture parts. Meanwhile, the spatial geometric error model under each topology is established, which provides a theoretical basis for the error compensation of the machine tools.

The micro-discharge tool setting method is to apply a certain voltage between the tool and the tool set. When the distance between the tool and the tool set is less than the discharge gap, the medium between the tool and the tool set discharges and the voltage decreases, monitoring the voltage signal and recording the machine coordinates when the voltage changes times to complete the tool setting process. In this paper, the influence of the times and duration of the discharge on the tool clearance and the shape of the tool nose during the micro-discharge tool setting process is studied. The research shows that the tool clearance is related to the discharge duration. When the duration of the discharge is less than 4s, the tool clearance becomes smaller with the increase of the times of tool setting process, and the governing tool nose damage is breakage by the discharge current impact. When the discharge duration is greater than or equal to 4s, the tool clearance becomes larger as the number of times of tool setting process increases. The burr that grows at the nose of the tool changes the nose shape. The above research provides support for the subsequent micro-discharge tool setting tool to achieve high-precision non-destructive tool setting process and optimize tool setting parameters.
