Broaching operations require stiff machine tools that have to withstand high cutting forces. This work aims to develop a methodology to predict the macroscopic cutting forces on a real, internal broaching operation comprising a large number of teeth. The macroscopic forces are estimated, based on the addition of local forces that are applied to each section and are simultaneously in contact with the broach. These local forces are calculated using a model of specific cutting pressure, depending on the rise per tooth. This study uses two methods to identify this specific cutting pressure model, that is, a direct approach based on orthogonal cutting tests and an inverse approach based on an instrumented broaching operation. It is shown that the direct method is effective in identifying a specific cutting pressure model and enables the prediction of macroscopic forces. Moreover, the direct approach provides more comprehensive results in terms of radial forces.

The paper structured into three parts outlines the present state of the broaching technology. The first part (Mechanik 5-6, 2021) highlighted possible process variants for internal and external operations and designs of broaching machines as well as CNC control systems and other advanced automatization forms. The second part (Mechanik 8-9, 2021) was devoted to the progressive broaching methods such as rotary broaching, hard broaching and MQL application. The third part discusses some important directions of experimental investigations carrying out for more efficient and reliable broaching processes.

“…Optimization process of broaching and reaming tools is continuous and uninterrupted. In this respect, one can see some recent publications: a paper dedicated to geometrical optimization of broaching tool [3]; articles dedicated to the analysis of the distribution of forces in the process of holes machining [4][5][6]; U.S. Patent of a new broaching tool, about which there are many new patents issued every year concerning new designs of tools, and this particular patent is only an example of such a continuous process [7,8].

This paper deals with hole-enlarging multi-ute drilling process. In this respect, the analysis of existing structures, their advantages and disadvantages is carried out and investigated. Cutting conditions during hole-enlarging multi-ute drilling process are shown. Herein, a new design of a hole-enlarging multi-ute drilling, as a holeenlarging multi-ute drill-broaching tool from broaching-speed steel with carbide plates, and a new way of handling new tools are presented. Hole-enlarging multi-ute drillbroaching combines the features of hole-enlarging multi ute drill (in cross-section) and those of broaching tool (in longitudinal section). In so doing, it is possible to increase the quality of hole-making (size variance, surface roughness) to facilitate cutting conditions and increase durability. The results of prototypes testing are presented in the end.
