A method for evaluating the contour and tolerance of the toroidal cutter with helicoidal surfaces
Measurement Science and Technology, 2000This paper presents a quality-evaluation model for a cylindrical-shank toroidal milling cutter. The complete toroidal cutter comprises three sections: a cylindrical shank, a truncated cone and a toroid. In machining practice, the cylindrical shank is held by the spindle-head holder and rotates about a central axis.

Influence of the toroidal cutter kinematics on elastic state of the machine parts surface bed
Science Intensive Technologies in Mechanical Engineering, 2022An approach to taut state increasing within elastic-plastic deformation zone in the process of surface plastic deformation has been viewed. The technical idea of solving the problem is based on the study of workplace tool kinematics. A new hard-ening process based on the workplace tool circular oscillation is proposed. To prove the effectiveness of the

Tool path generation for five-axis sculptured surface machining with a toroidal cutter
International Journal of Machining and Machinability of Materials, 2010This paper presents an algorithm to generate tool paths for five-axis sculptured surface machining with a toroidal cutter based on optimal tool position and orientation. The toroidal cutting surface offers a large range of radius of curvatures. Furthermore, the cutter orientation varies depending on the curvature of surface.

Constant Scallop Height Algorithm of Self-Adaptive Tool Orientation with Toroidal Cutter
Advanced Materials Research, 2012Using a 5-axis NC machining tool enables the tool to be oriented in any spatial direction to access a given point. This means interference can be avoided and the position of the tool can be optimized. This paper presents a new approach to generate gouging-free tool paths for constant scallop-height machining using 5-axis toroidal milling.

Isoscallop of Self-Adaptive Tool Orientation with Toroidal Cutter under Optimum Orientation of MCPs
Advanced Materials Research, 2012End-milling of free-form surfaces on 5-sxis NC tools is a complex problem which has been studied by a large number of research scientists. When end-milling non-convex surfaces, there is a risk of interference between the tool and the surface. This paper presents a new approach to generate gouging-free tool path for constant scallop-height machining ...

Prediction of cutting forces and vibration in titanium alloy milling using a toroidal cutter
International Journal of Advanced Manufacturing Technology, 2017Titanium alloys are frequently used when a high strength-to-weight ratio and good hot hardness, corrosion resistance, and fatigue properties are needed. One of the most widely used of these alloys is Ti-6Al-4V. However, titanium alloys with these characteristics generally have poor machinability and tend to cause the machine-tool-workpiece-fixture ...

Local Gouge Detection Algorithm for 5-Axis Sculptured Surface Machining Using the Toroidal Cutter
Advanced Materials Research, 2011Based on the geometrical property of the toroidal cutter, an improved local gouge detection method for 5-axis sculptured surface machining was presented here. By alternately taking full advantage of point projection principles on curve and surface, the minimum distance between the circular curve of the toroidal cutter and the design surface was firstly

Surface swept by a toroidal cutter during 5-axis machining
Computer-Aided Design, 2001This paper presents a method of determining the shape of the surface swept by a tool that follows a 5-axis tool path for machining curved surfaces. The method consists of discretising the tool into pseudo-inserts and identifying imprint points using a modified principle of silhouettes.
