“…1(b), that deal with material removal as the tool spins around its axis. The physical shape of the tool (e.g., the number of teeth) affects cutting force Sun et al [2013]; Larue and Altintas [2005]; Zhang et al [2016]; Xu et al [2017] and vibration Sonthipermpoon et al [2010]; Lu et al [2014], which can affect the quality of flank milling. A post-process may need to regulate the speed as the tool follows our tool path.…”

“…Mathematical modeling of the cutting force under the flank milling is also an active research area, see e.g. [25,26,27,28,29] and references cited therein. Looking for toolpaths that minimize (the mean value of) the tool deflection force are studied in [30].…”

“…Another physical factor strongly correlated to the cutting force is not only the vibration of the milling tool but also of the milled object itself. Vibration phenomenon of thin impeller blades during flank milling is discussed in [27]. An optimization-based approach that incorporates physical properties such as stiffness or vibrations is proposed in [31].…”

A new method for 5-axis flank computer numerically controlled (CNC) machining using a predefined set of tappered ball-endmill tools (aka conical) cutters is proposed. The space of lines that admit tangential motion of an associated truncated cone along a general, doubly curved, free-form surface is explored. These lines serve as discrete positions of conical axes in 3D space. Spline surface fitting is used to generate a ruled surface that represents a single continuous sweep of a rigid conical milling tool. An optimization based approach is then applied to globally minimize the error between the design surface and the conical envelope. Our computer simulation are validated with physical experiments on two benchmark industrial datasets, reducing significantly the execution times while preserving or even reducing the milling error when compared to the state-of-the-art industrial software.

The paper presents a method of forecasting the product surface topography after five-axis machining with a lens-shaped end-mill. Surface roughness is one of the key parameters considered when assessing the effectiveness of the machining process, especially in the aviation, automotive, tooling and medical equipment industries. The developed method, the first published, presented in the paper is based on the analytical equations of the trajectory of the cutting edge motion, on the basis of which the cutter action surface is generated. The developed model takes into account: cutting depth, cutting width, feed, lead angle and radial runout. Experimental studies were conducted using three different materials: 40HM steel, Al7035 aluminum alloy and Ti Grade 5 titanium alloy. Various values of the cutting width parameters and different feeds were used in the tests. Based on the results of the experimental tests, an empirical model (response surface model) was determined and was then used to verify the simulation model. The simulation results and the results of experimental tests were compared and conclusions were drawn regarding the developed models. The developed models supported by numerical simulation can be used to approximately estimate the influence of the width of cut br and feed ft on selected height characteristics Sa and Sz^ of the geometric structure of the surface (GSS) after machining with a lens-shaped end-mill in terms of the process parameters adopted in the tests. It was found that the influence of the ft on the Sa and Sz^ is greater for small values of br. The effect of br is greater with lower ft values. The cutting width br has the greatest influence on Sa and Sz^, and ft and the interaction of these parameters has the least influence.
