Time-optimal feedrate scheduling with actuator constraints for 5-axis machining

چکیده
Cycle time minimization is one of the major goals to achieve in manufacturing. Maximizing feedrate direct solution; however, physical motions need be under specified motion limits avoid high-frequency vibration, causing machining error. In this paper, a time-optimal scheduling approach with corner smoothing for 5-axis G1 toolpaths presented machining. One key feature proposed method describe orientation toolpath spherical coordinate system (SCS), instead commonly used unit sphere. With this, position and are integrated become hyper-curve 5-dimensional (5-D) space. The designed 5-D hyper-curve. Thus, no synchronization needed, making easier. A quintic B-spline utilized smoothen sharp corners toolpath. Then, S-shape profile each block optimized actuator constraints, objective minimizing cycle time. Particle swarm optimization (PSO) provide solution. Experiments conducted validate approach, results compared two other existing approaches. It found that can shorter less contour errors, showing effectiveness approach.

In order to perform the machining of molds, the shapes and desired tool paths designed using CAD/CAM systems are typically appr...
متن کاملAutomatic feedrate adjustment for pocket machining
As high-speed machining and unmanned machining become common, the demand for cutting-load regularization increases, so NC machining can be more ef®cient. To be presented is a simple cutting-load regularization method for pocket machining. As the conventional off-line approaches where cutting-load is predicted and cutting parameters are adjusted before actual cutting, the proposed method require...
متن کاملOptimal grids for five-axis machining
This paper presents a new grid generation method for tool path planning for five-axis machining based on minimization of the kinematics error. First, the procedure constructs a space-filling curve so that the scallops between the resulting tracks of the tool do not exceed a prescribed tolerance. At the second stage (which is the subject of this paper) a one-dimensional grid along the space-fill...

متن کاملDynamic approach of the feedrate interpolation for trajectory planning process in multi-axis machining
Feedrate interpolation, which consists in generating the set points sent to the axis controllers from the initial path, constitutes a major line of the trajectory planning process. In multi-axis high speed machining the feedrate is usually evaluated by a kinematic method as the maximum feedrate respecting the joint velocity, acceleration an jerk limits. However this approach requires a difficul...
