“…Its alteration makes it possible to produce a tool with the flute shape, as close as possible to required. Literature is using algorithms to solve both the direct [32][33][34][35] and the inverse problems in profiling the helical flutes [36][37][38][39][40][41][42][43][44]. Simulating relative positions of the profiling tool and of the workpiece is basically performed in AutoCAD, NX, and CATIA environments [45][46][47][48].…”

“…Abrasive machining has been the main method for finishing machine parts [1]. The manufacture of cutting tools [2][3][4][5][6] and grinding of helical grooves [7] from modern tool materials is critically important for the production of high quality parts. Active depth grinding technology is one of the most efficient ways to manufacture tool structures and machine parts from hard and brittle materials with high surface quality and dimensional accuracy [8][9][10][11][12].…”

In this paper, a set of indicators for an effective assessment of the cutting ability of a grinding wheel was established based on the detection of the degree of filling and immersion of abrasive edges. It has been pointed out that a profile of a populated circle has a direct correlation with the average number of recognized faces. A new indicators for measuring zones with active edges and their distribution on the surface of a grinding wheel was developed, which can be identified by the models algorithms, is formed

“…Due to its major influence on the geometry and quality of the cutting edge, flute grinding is considered to be the most important process step. Besides its dominating influence on the cutting-edge generation, flute grinding also has the highest material removal Vw which goes along with a high primary processing time [1,2]. To maximise productivity and increase economic efficiency, the flute is usually manufactured by creep feed grinding The grinding of helical flutes is especially challenging.…”

Resource efficiency is gaining relevance in every aspect of production. Hence, cutting tools are exposed to high demands regarding productivity and quality. Considering the various grinding operations in tool manufacturing, flute grinding is the most significant process step as it defines the peripheral cutting edge and the rake face. Therefore, it has a substantial influence on the machining behaviour of, for example, milling tools. When it comes to helical flutes, the complex contact conditions between grinding wheel and tool blank during the multiaxial grinding process are particularly difficult to determine. Due to the lack of knowledge about those contact conditions, the grinding wheels typically used for flute grinding cannot wholly meet the actual process requirements. In order to optimise the design of the grinding wheels, a numerical model was developed. Based on that, a simulation tool was implemented to analyse the complex contact conditions during flute grinding depending on the process parameters and tool/workpiece geometry. The influence of different grinding parameters on the effective contact length, the specific material removal rate and the equivalent chip thickness was evaluated by employing the computer-based model. The generated results were then used to develop a new optimised tool concept for a more efficient flute grinding process.
