A hybrid analytical and discrete based methodology to calculate path scallop of helical toroidal cutter in five-axis milling [PDF]
FME Transactions, 2018 This paper presents a new method to calculate path scallop height of toroidal cutter during free-form surface machining in five-axis milling. The scallop height was defined as the distance between the tool intersection point and the normal point on the ...

Modelling of the Face-Milling Process by Toroidal Cutter
Materials, 2023 When face milling using a toroidal cutter, with a change in the depth of the cut, the entering angle varies as well. An experimental test of the influence of cutting parameters, such as the depth of the cut and the feed per tooth on the cutting force components and surface roughness parameters, was conducted. The experimental test was carried out using

A new method for choosing between ball-end cutter and toroidal cutter when machining free-form surfaces [PDF]
International Journal of Advanced Manufacturing Technology, 2020 End-milling of free-form surfaces on multi-axis CNC machines are complex and expensive operations involved in the production of many high-value parts, molds and stamping dies. For such operations, the choice of the cutter type to use is very important given the considerable impact of this choice on the quality of the machined surface and the duration ...
