摘要

提出了一种适应工业机器人轨迹规划阶段以实现连续加工的实用方法。首先,引入L1插值,高效地生成保形五次样条形式的刀具轨迹;然后,在考虑关节运动学约束的情况下,采用平动受限模式,在笛卡尔空间中进行刀尖进给速度规划。在六轴工业机器人上进行的实验验证验证了所提出的轨迹规划方法在加工环境下的有效性。

Enhanced trajectory planning for machining with industrial six-axis robots
This paper presents a practical approach to adapt the trajectory planning stage for industrial robots to realize continuous machining operations. Firstly, L1 interpolation is introduced to generate efficiently the tool-paths in the form of shape-preserving quintic splines. Then, the tool-tip feedrate planning in Cartesian space is done using a smooth jerk limited pattern and taking into account the joints kinematics constraints. Experimental validations conducted on a 6-axis industrial robot demonstrate the effectiveness of the proposed methodology of trajectory planning in the context of machining.
