“…In order to obtain an efficient computational method for curvilinear discretization we decided to use a numerical method which was recently proposed by Nagata (2005) and has already been applied successfully to diverse engineering problems (Neto, Oliveira, Alves, & Menezes, 2010;Neto, Oliveira, Menezes, & Alves, 2012;Boschiroli, Fünfzig, Romani, & Albrecht, 2011;Sekine, & Obikawa, 2010). The main idea behind this parametric surface description (subsequently named Nagata patch) is the quadratic discretization of a curved segment from the position and normal vectors at the end points.…”

This paper presents methodologies to discretize nominal robot paths extracted from 3-D CAD drawings. Behind robot path discretization is the ability to have a robot adjusting the traversed paths so that the contact between robot tool and work-piece is properly maintained. In addition, a hybrid force/motion control system based on Fuzzy-PI control is proposed to adjust robot paths with external sensory feedback. All these capabilities allow to facilitate the robot programming process and to increase the robots autonomy.Comment: Expert Systems with Application

“…In this section, path interval determination suitable for filleted end milling is newly proposed in contrast with the milling process simulation. In ball end milling, path interval determination is commonly applied as the procedure using the relationship between a path interval and scallop height on an instantaneous section (20,21) . [-] 2…”

This paper focuses on the mathematical modeling for 5-axis milling with a filleted end mill. Several coordinate systems are introduced to describe the relationship between a cutter orientation and a machined surface. Then, a cutting point on a cutting edge is geometrically formulated as an integrated form of some expressions. The fundamental simulations based on the modeling were implemented to investigate the characteristics of path-interval and feed-interval scallops on a machined surface; moreover, path interval determination is proposed for suitable estimation in filleted end milling. As a result, it was found that the proposed approach could provide the characteristics of microscopic topography in detail.

“…The machine movement produced by CAM has great influence on surface quality, machining efficiency, etc. in practical milling process, so that tool path generation has been studied for the further advancement of milling [13][14][15]. However, there still exist the further demands awaited highly such as higher machining speeds and longer tool life.…”

This study describes remarkable characteristics of a novel path interval determination in filleted end milling with a tool inclination. CNC milling machine is one of the core technologies in practical manufacturing. Computer-aided technologies have contributed to the technological advancement. Tool path generation in computer-aided manufacturing is really important for CNC milling process. Although there are a lot of parameters treated in tool path generation, path interval is one of the influential factors in considering the balance between manufacturing efficiency and machined surface feature. A path interval determination in filleted end milling commonly entails the intersection problems with mathematical complexities in essence. The related studies have been reported so far, while there has scarcely been a procedure to cope effectively with the complexities. Hence, this study focused on a novel path interval determination proposed in our previous study. After the analytical discussions were made with the computational and experimental results, it was acquired from the explicit evidences that the novel procedure possessed remarkable characteristics contributable for a path interval determination in multi-axis filleted end milling.
