“…Table 2 presents some researches in FFM which discussed trade-off between machining variables [29][30][31][32][33][34]. This trade-off occurs because of the sculptured surface characteristics from which happen the start-stop and acceleration and deceleration of the feed of the tools, or it is known as dynamic behaviour of the machining tools in FFM [5].…”

“…There are 57 articles discussed about machining time and toolpath, only 1 other article discuss machine time without discussing tool path Related with dynamic behaviour of the machining tools in FFM mention by [5], there are 22 articles discuss about dynamic machining behaviour, 5 articles discuss about feed rate scheduling, and 2 out of those discuss both topics.…”

“…Literature studies shows some topics of interest in SDR due to the complexity of the problems related to the sculptured characteristics of the machining cavity walls. In products with prismatic and rotational features, the machining time is linear with the tool path length, but on the sculpture surface, the machining time is not linear to the length of the machining surface as the consequence of the acceleration and deceleration of the feed rate [3][4][5] caused by changes in the surface contour of the sculpture and differences in critical distance (CD) in each layer so that it requires tools with different diameters for each cutting layer. Compared to the machining process for making cavities with prismatic or rotational shapes, the machining process for SDR with sculptured surface/ walls requires a different approach.…”

“…There are several research topics in FFM 3-axis milling machines objectives, such as energy savings [7][8], machining time [9][10], surface roughness and tool life [11]. Some other topics are related with the characteristics of sculptured surface that need to be considered in setting the FFM objectives, such as dynamic behaviour of machining and feedrate scheduling [5,11], subdivision of machining area and tool allocation [4,[13][14][15], and prediction and evaluation of process parameters [6]. These topics arise because the geometric contours of the FFM are different from rotational and prismatic features [6].…”

Sculptured-dies roughing (SDR) has some different objectives that maybe contradicting and therefore needs trade-off among them. Compared to prismatic and rotational shape machining, SDR is more complex considering the sculptured characteristics of machining surface. Layer-by layer approach applied in SDR requires multiple tools selection and determination of the depth of cut for each cutting layer. Those decisions need to be considered in SDR optimization problem. The trade-off between different objectives are required, such as machining residues/cut-off (or coverage) from the roughing process to be traded-off with the machining (roughing) time. This paper presents a stateof-the-art review on cutting layer and cutting tools selection (CLT) by multi-objective optimization for SDR and presents the needs for a trade-off between machining time and cut-off (residual volume) by minimizing machining Time per Volume Coefficient (TVC). The process is conducted simultaneously. A systematic literature review is presented to show the complexity of the geometric related problem, the optimization techniques that have been applied, and the different objectives in SDR, including some multi-objective coverage. Finally, some directions on algorithms for optimizing TVC in TLC problem is presented. Considering the combinatorial problem in CLT, this paper overviews the Multi-Objectives Dynamic Programming approach (MODP) and Metaheuristics Multiple Objective approaches (MOGA etc.) for CLT problem optimization. The results confirm that the optimum tools combination and cutting layer selection could increase SDR efficiency. The paper conclusion discussed recommended metaheuristic approach to trade-off between machining time and residual volume in more complex problem.
