“…Each graph vertice and edge define some tool structure part, its structural component or the structure part or structural component parameters. A set of options of structural component layout of the broach structure operation part is represented by a set of graph traversals [17][18][19][20][21].…”

“…The key factors defining the strength, stiffness and long life cycle of the broach structure are structural and geometrical parameters of teeth: step t, chip groove depth (tooth height) h, length of a rear side b, tooth thickness g with average height, face γ and back α angles, radii of chip groove rounding-off r and tooth back radius R, cutting edge form (availability of chip separation fillets or grooves) [1,[7][8][9][19][20][21].…”

The authors considered a methodology for the automated design of cylindrical broach structures consisting of the following stages: forming a 3D-parametric geometrical broach image, assessing a broach structure stress-strain state during operation. The paper presents the results of software implementation of the algorithm for forming a broach structure parametric model from 3D-geometrical prototypes in the system Solidworks. To assess a stress-strain state of tools with the numerical method of finite elements in Solidworks Simulation, the authors formed an analytical design model taking into account strain of geometric prototypes. A series of numerical experiments was aimed at researching a stress-strain state of broach teeth under cutting forces action. According to the results of numerical experiments, by means of the least square method the authors obtained analytical expressions to estimate the influence of geometrical and design parameters of the broach teeth structure on elastic displacements of cutting edges vertice and equivalent stresses of the most loaded teeth components. The authors developed recommendations on the change of the teeth section parameters allowing for the extension of the broach structure operation life and reducing the tool life consumption for the batch of parts.
