“…The tolerance was controlled by selecting the overlapping time. Tajima and Sencer [83] proposed the velocity blending method based on the jerk limited acceleration profile (JLAP). The proposed algorithm was reported to be able to achieve better performance than the spline based corner rounding method by reducing the overall cycle time 6-7%.…”

Driven by the ever increasing demand in function integration, more and more next generation high value-added products, such as head-up displays, solar concentrators and intra-ocular-lens, etc., are designed to possess freeform (i.e., non-rotational symmetric) surfaces. The toolpath, composed of high density of short linear and circular segments, is generally used in computer numerical control (CNC) systems to machine those products. However, the discontinuity between toolpath segments leads to high-frequency fluctuation of feedrate and acceleration, which will decrease the machining efficiency and product surface finish. Driven by the ever-increasing need for high-speed high-precision machining of those products, many novel toolpath interpolation and smoothing approaches have been proposed in both academia and industry, aiming to alleviate the issues caused by the conventional toolpath representation and interpolation methods. This paper provides a comprehensive review of the state-of-the-art toolpath interpolation and smoothing approaches with systematic classifications. The advantages and disadvantages of these approaches are discussed. Possible future research directions are also offered.

“…In Sencer et al (2015); Tajima et al (2018), chains of FIR filters are used in interpolation problems for online planning of multi-dimensional trajectories with time and frequency specifications. In the field of multi-dimensional interpolation, it is worth mentioning that also B-splines can be generated via a chain of FIR filters, see Biagiotti andMelchiorri (2011, 2013).…”

This paper starts from the results reported in the article "FIR Filters for Online Trajectory Planning with Time-and Frequency-Domain Specifications", where the use of a cascade of FIR (Finite Impulse Response) filters for planning minimum-time multi-segment polynomial trajectories, i.e. trajectories composed of several polynomial segments, under constraints of velocity, acceleration, etc. is proposed. In particular, in that paper the relationship between the limits acting on the trajectory derivatives (i.e. velocity, acceleration, jerk, etc.), and the parameters of the filters is deduced, along with a set of constraints among these parameters that guarantees the time-optimality of the trajectory in the rest-to-rest case, that is with null boundary conditions on the trajectory derivatives. However, the choice of the parameters, when these conditions are not satisfied, was still an open problem, at least

“…Okwudire and Ding [14] used optimal control to generate time-optimal cornering trajectories. Weck and Ye [26] and recently, Sencer et al [27] investigated on filtering techniques to accurately travel along sharp corners. Tsai and Huang [28] investigated incorporation of servo dynamics into cornering trajectory generation to improve dynamic contouring accuracy.…”
