In the course of the first funding period, new regrinding methods for numerical controls by means of clothoids for the straight-straight, straight-circle and circle-circle transitions in the two-dimensional space have been successfully investigated and developed. Due to the linear and controllable curvature outline, the clothoid regrinding enables a limitation of the jerk and the transverse acceleration. In most cases, this results in a high and smooth velocity. This, in turn, can lead to an improved productivity and surface quality. With the smooth dynamic profile the clothoid regrinding also helps to protect and conserve drives and mechanics.In this funding period the focus will be on the analysis and development of clothoid splines as a two-dimensional interpolation method for numerical controls. According to the available interpolation types in the state of the art, interpolating as well as approximating methods based on clothoids will be implemented.As in the first funding period in this project a version of the developed algorithms will be executed in a real-time environment and ported to an NC kernel. This is to demonstrate the advantages of clothoids for the interpolation over current methods.

在第一个融资期间，已经成功地研究和开发了二维空间中的直线，直圈和圆圈转换的新型数值控制方法。由于线性且可控的曲率轮廓，衣服的重新磨碎可以限制混蛋和横向加速度。在大多数情况下，这会导致高速度。反过来，这可以提高生产率和表面质量。借助平滑的动态剖面，衣服再研磨也有助于保护和保护驱动器和力学。在此资金期间，重点将放在塑料样条作为数值控制的二维插值方法上的分析和开发。根据最新技术状态的可用插值类型，将实施插值以及基于衣服的近似方法。在该项目的第一个资金期间，将在实时环境中执行开发算法的版本，并移植到NC内核。这是为了证明与当前方法相对于当前方法的插值的优势。
