Summary: This paper proposes a method for generating iso-scallop tool paths based on uniform scallop height. The method is able to minimize the total length of the tool path while maximizing the interval between cutter location points. By iteratively calculating scallop points based on a discrete feature point set, the method improves computational efficiency. Experimental results show that the generated iso-scallop tool paths have uniform scallop height and shorter total lengths compared to iso-planar tool paths.

Summary: A contour parallel tool path generation method for pocket machining is developed based on sound field synthesis theory. The method extracts the simplified medial axis tree of the pocket and obtains the final tool path through sound field synthesis. Experimental results demonstrate that the tool path obtained by the novel method has advantages in improving machining quality and efficiency.

Summary: Tool path planning is crucial for multi-axis machining to fully utilize machine tools' producing capabilities. While most studies focus on tool path topology, research on tool orientation planning is limited. Various factors like interference and collision pose challenges on tool orientation planning, highlighting the importance of high precision in generating time-optimal tool paths.

Summary: This paper introduces a novel method for generating adaptive spiral tool paths for CNC machining of complex sculptured surfaces without the need for surface fitting. The algorithm utilizes a uniform 2D circular mesh to compute cutter location points, which are then refined adaptively to eliminate redundancy in machining and minimize tool lifts. The developed system was found to be more efficient and robust than commercial CAM software in terms of surface quality, productivity, and memory requirements.

Summary: This paper presents a geometric smoothing algorithm for five-axis machining of curved surfaces, which smooths linear tool path segments to avoid undesired marks on finished surfaces. The proposed algorithm ensures continuity of first, second, and third geometric derivatives at meeting points of splined path segments to achieve smoother tool-tip and tool axis orientation, reducing tracking errors and contour errors.
