“…He indicates how to choose the parameters of a broach, but it does not establish neither a methodology to simulate the cutting forces nor an evaluation of the cutting parameters in each discretized section of the broach. To determine broach parameters, Terry et al (1992) did not proceed by simulation of cutting forces, but by a series of equations like Taylor's tool life equation and maximum stress admitted by the broach. This solution, computer-assisted, proposes broach parameters not far away from the norms because the equations implemented in this software come from the norms themselves.…”

International audienceThis article proposes a simulation of cutting forces in broaching of fir tree slots. Every step needed to build an in-house fir tree broaching simulation is presented. This simulation is based on the discretization of each tooth of the broach, computation of elementary cutting forces of each discretized section, and finally the summation of each elementary cutting force into a global axes system. This work also presents orthogonal cutting experiments to implement realistic specific cutting forces into the model. The simulation obtained is compared with the real force signals of a fir tree broach to evaluate the quality of the simulation. At the end, the application to industrial context is developed

“…Redesign is a potential solution where several iterations may be required with the added expense of increased time, cost, and effort (Salomone 1995). Various other researchers have investigated applying concurrent engineering for optimizing product design (Dowlatshahi 1992, Terry et al 1992, Noble and Tanchoco 1993, Luh et al 1999. However, the application of CE to projects commonly results in cost overruns or time delays due to the uncertainty associated with freezing of the design in the early stages of the project (Amornsawadwatana et al 2003).…”

Concurrent Engineering aims to incorporate the overlapping of processes in order to reduce its time-to-market and thereby sustain the existence of organizations in increasingly competitive times. Although faster product design, development, and delivery are the intended outcomes of concurrent engineering, one of the undesirable by-products is an increase in risks as a consequence of uncertainties between interdependent processes. Hence, the risks need to be identified, assessed, and mitigated together with concurrent engineering considerations for the elimination of the 'domino-effect' within risk management. This paper concentrates primarily on knowledge elicitation techniques that were used to provide information to the Intelligent Risk Mapping and Assessment System (IRMAS TM ) to identify, prioritise, analyse, and assist project managers to manage perceived sources of CE risks. Techniques such as expert interviews, brainstorming, the Delphi technique, and the analogy process are discussed in relation to compiling the knowledge used for this expert system. A total of 589 risk items were identified for different project types, and information on 4372 items and 136 lessons learned were collected from experts at HdH. The core of the research is a reasoning methodology used for Knowledge Elicitation of a Risk Mapping and Assessment System which will not only support the decisionmaking process of the user but also aid the knowledge retrieval, storage, sharing, and updating process of manufacturing organizations. This research provides a systematic engineering approach to risk management of concurrent product and process development.

“…Since the number of simultaneously engaged cutting edges with the workpiece is relatively high in broaching, the chip load on each individual cutting edge is smaller and tool life is distinctively longer than other machining operations. 1 In addition, broaching machines are not as sophisticated as CNC milling or CNC turning machines; thus, a highly skilled operator is not necessary to run the broaching machine.…”

“…Gilormini et al 4 analyzed the cutting forces on a single broaching and compared them to the forces in slotting and tapping processes. Terry et al 1 presented a system for optimal design of broaching tools. They presented the factors that affect productivity in broaching and explained the design constraints, their importance, and their selection method.…”

Prediction of cutting forces is one of the fundamental stages in the modeling of machining processes. The costly machining tests can be replaced by virtual simulations where cutting parameters and material properties can be altered repeatedly with no cost. Broaching is one of the machining operations which is extensively used in the industry. The geometry of broaching tool varies according to the desired profile of the workpiece which can be a simple line or complicated curves. This broad range of geometries imposes complexity on the distribution of the chip load along the cutting edge. Therefore, introducing a practical force model for broaching operation can be challenging. An attempt is made in this paper to present a force model for broaching. The newly proposed force model expresses the cutting edge as a B-spline parametric curve and uses its flexibility to calculate the chip load as well as cutting forces for orthogonal and oblique broaching. Verified by previously published experimental results, the presented model has a great capability to simulate broaching cutter geometry along with cutting forces.
