十年前，在芝加哥出现了一种基于并联运动学结构的新型机床。从那时起，许多这些并联运动机器（PKM）已在世界各地开发。他们的主要兴趣在于其高动态特性，这有助于在高速铣削中更快地进行。为了开发PKM刀具的高速铣削并突出其潜力，法国实验室IRCCyN现在配备了VERNE。该PKM工具由西班牙公司Fatronik开发。然而，高速铣削加工是一项复杂的任务，其中大量的参数影响零件的最终精度和机器的生产率。例如，NC（数控）和计算机辅助制造（CAM）参数（前馈、铣削策略等），工件几何形状、机床结构、刀具等，对最后的部分有直接的影响。因此，开发了一种方法，以检查机器（串行或并行）在铣削中的能力，这依赖于两种方法。第一种是实验方法（使用坐标测量机或获取输出轴编码器），而第二种是模拟方法。在介绍了运动学的VERNE，实验方法进行到目前为止，将提出。
Abstract Ten years ago a new kind of machine tool was presented in Chicago, based on parallel kinematics architectures. Since then, many of these parallel kinematics machines (PKMs) have been developed around the world. Their main interest lies in their high dynamic characteristics, which could help in going faster in high-speed milling. In order to develop high-speed milling on PKM tools and to highlight their potentialities, the French laboratory IRCCyN is now equipped with the VERNE. This PKM tool has been developed by the Spanish company Fatronik. However, the high-speed milling production process is a complex task, in which a great number of parameters influence the final precision of the part and the productivity of the machine. For example, the NC (numerical control) and computer-aided manufacturing (CAM) parameters (feed forward, milling strategies, etc.), the piece geometry, the machine structure, the tool, etc., have a direct consequence on the final part. Hence, a method has been developed in order to check the capability of the machine (either serial or parallel) in milling, which relies on two approaches. The first one is an experimental approach (either using a coordinate measuring machine or acquiring the output axis encoders), while the second one is a simulated approach. After introducing the kinematics of the VERNE, the experimental approach performed so far will be presented.
