Problems solved by technology

However, in the processing of oral prosthesis, the processing requirements of different regions are different, and the trajectory shape is also completely different. A single speed planning method is difficult to meet all situations. It is necessary for the system to adaptively select the corresponding Velocity Planning Method

Abstract

The invention provides a numerical control processing method for a dental restoration body. The method comprises the following steps of: determining the type of an interpolation track section by applying a set of classification standard to the interpolation track section according to a result obtained by applying the set of classification standard to the interpolation track section, wherein the interpolation track section is divided into a first type, a second type and a third type; and processing the interpolation track section by different dental restoration body numerical control processing methods according to the type of the interpolation track section so as to mold the dental restoration body, wherein the dental restoration body numerical control processing method comprises a first speed planning method, a second speed planning method and a third speed planning method. By the numerical control processing method for the dental restoration body provided by the embodiment of the invention, tracks in different areas are classified; and by different corresponding subsequent processing methods, the processing time of the dental restoration body can be remarkably saved, the processing efficiency can be improved, and the accuracy of the dental restoration body can be ensured at the same time.

Description

technical field [0001] The invention relates to the technical field of numerical control processing of oral restorations, in particular to a numerical control processing method of oral restorations. Background technique [0002] Modern CAD / CAM technology has been widely used in the field of oral restoration processing. However, the surfaces of oral restorations are mostly complex curved surfaces, and the processing object is zirconia, a special brittle material. The existing oral restoration processing systems have problems of low efficiency, precision and difficult control of the process. Material processing technology requirements and improving processing efficiency as much as possible are key issues in the field of oral restoration processing. [0003] In the high-end CNC system, the speed forward planning technology is generally used to avoid frequent start and stop of the processing process, reduce the speed fluctuation to achieve the processing effect and improve the ...
