Optimisation of Planning Parameters for Machining Blade Electrode Micro-Fillet with Scallop Height Modelling [PDF]
Micromachines, 2021 Aero-engine blades are manufactured by electroforming process with electrodes. The blade electrode is usually machined with five-axis micromilling to get required profile roughness. Tool path planning parameters, such as cutting step and tool tilt angle,

Surface quality enhancement by constant scallop-height in three-axis milling operations
Results in Surfaces and InterfacesThe quality of machined part surfaces are under the impact of scallop height which should be analyzed and minimized. Achieving a uniform scallop-height is important for ensuring a smooth surface finish and maintaining consistent material removal across ...

Analytical method for calculating scallop height of helical toroidal cutter in five-axis milling [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2020 This paper proposed a method to determine the path scallop of toroidal cutter in five-axis milling during a complex surface machining. A mathematical algorithm was developed by taking into consideration the impact of the helical angle and inclination ...

An analytical model taking feed rate effect into consideration for scallop height calculation in milling with torus-end cutter [PDF]
Journal of Intelligent Manufacturing, 2017 Feed rate effect on scallop height in complex surface milling by torus-end mill is rarely studied. In a previous paper, an analytical predictive model of scallop height based on transverse step over distance has been established. However, this model doesn’t take feed rate effect into consideration.

Optimization of Tool Path for Uniform Scallop-Height in Ultra-precision Grinding of Free-form Surfaces [PDF]
Nanomanufacturing and Metrology, 2019 Free-form surfaces have been widely used in complex optical devices to improve the functional performance of imaging and illumination quality and reduce sizes. Ultra-precision grinding is a kind of ultra-precision machining technology for fabricating free-form surfaces with high form accuracy and good surface finish.

Procedia Engineering, 2017 Abstract Generating the best surface quality with minimum machining time is the main objective of CNC milling. Modern CAM systems do not always ensure constant scallop height even though an appropriate option has been specified for CNC program generation.

Constant Scallop-height Machining of Free-form Surfaces [PDF]
Journal of Engineering for Industry, 1994 A novel approach for the NC tool-path generation of free-form surfaces is presented. Traditionally, the distance between adjacent tool-paths in either the Euclidean space or in the parametric space is kept constant. Instead, in this work, the scallop-height is kept constant.

Chinese Journal of AeronauticsIso-scallop height machining means, when machining a freeform surface, the scallop height between any two neighboring tool paths on the surface will be a constant (i.e., the given threshold), which is preferable among various freeform surface machining strategies due to its high machining efficiency as well as better machine tool's dynamics.
