“…(Zhang, et al, (2018) developed off-line feed-rate optimization techniques. While (Liang, et al, (2017), (Ridwan, et al, (2012b) focused on feed-rate scheduling to improve processing efficiency. Numerous studies (Lie Tang & Landers, 2012), (Karunakaran & Shringi, 2008), (Ratava & Lohtander, 2018b) and (Ridwan, Xu, & Ho, 2012a) proposed various adaptive feed-rate methods to achieve efficiency and precision.…”

<p>Informed production decision-making requires a structured understanding of the production process and costs associated. This research proposes a decision support system incorporating the learning effects on selecting cost-effective machining production process. The approach is applied to the case on manufacturing wind turbine blades. The machining industry has experienced a surge in demand for complex machining applications and an availability of a wide range of new machining technologies. Producing complex structures requires experienced CNC programmers that perform extensive strategy planning, design and optimization. The system developed considers the production processes, cost items, power learning curve and experience of the programmers. This enables managers to evaluate between various production processes and select the most cost-efficient process. An analytical approach to evaluate cost efficiency between 3-axis CNC and 5-axis CNC machines. The result is a user-friendly planning and selection tool aiding in answering critical managerial questions related to cost-effectiveness.</p><div><br></div>

“…On the other hand, one of the key factors to deliver the smooth feedrate profile is to confine jerk under a specific limit. Thus, many jerk-limited feedrate designs, such as time-optimal [13,14], sine-shape [15], and S-shape [16][17][18], were introduced. Among others, the S-shape feedrate design is commonly adopted due to its simplicity and smoothness.…”

Cycle time minimization is one of the major goals that many manufacturers are eager to achieve. Maximizing feedrate is the direct solution, however, physical motions need to be under the specified motion limits to avoid high-frequency vibration, causing machining error. In this paper, a time-optimal feedrate scheduling approach for 5-axis G1 toolpath is presented for 5-axis machining. A quintic B-spline corner smoothing method is utilized to smoothen sharp corners in the toolpath. Then, the S-shape feedrate profile of each block is optimized under the actuator motion constraints, with the objective of minimizing the cycle time. Particle swarm optimization (PSO) is used to provide the optimized solution. Experiments are conducted to validate the proposed approach and the results are compared with two other existing approaches. It is found that the proposed method can achieve shorter cycle time and less contour errors, showing the effectiveness of the proposed approach.

“…The existence of such surfaces is complicated by the modification of polynomials and NURBS surfaces. NURBS is one of the most popular and successful methods for designing complex surfaces in computer-aided manufacturing [25][26][27][28][29], geometric design (CAD) and computer graphics [30][31][32][33][34][35].…”

Shaped plates with a special shape of texture on the front surface are widely used in the production of products of complex shapes from heat-resistant materials. An important stage of technological preparation for the formation of a system for the automated production of plates using laser ablation is the assignment of recommendations for the shape of the front surface. The technical result is ensured by the rational shape of the front surface of the replaceable multifaceted plate, which meets the requirements of manufacturability and increased performance when using it. Placement on the front surface of a microrelief, which is formed by a set of holes in the form of a group of micro-holes with a radius of 20-40 μm, a depth of 20-40 μm, which ensures the placement and retention of a suspension based on molybdenum disulfide during drilling, and the coordinates of the centers of the holes are determined by new analytical dependencies. This technological solution will significantly increase the speed of writing programs to control machines for laser ablation.
