... force and torque. Drilling experiments showed a net reduction of 17.18% in thrust force and 26.98% in torque while machining Ti–6Al–4V using the flute and margin textured tool, which justified the effectiveness of micro scale textures in minimizing the chip evacuation forces. The experimental analysis...

... the tool path. The feed is adjusted by limiting feed-dependent peak outputs to a set of user-defined constraints. The constraints are the tool shank bending stress, tool deflection, maximum chip load (to avoid edge chipping), and the torque limit of the machine. The linear and angular feeds of the tool...

..., can be calculated using this model from experimentally measured values of the instantaneous thrust force and torque. Good matches between the calculated shear strengths and the handbook values for thermally drilling low carbon steel confirm the model’s validity. 01 12 2006 24 09 2007 06...

... to match the measured and modeling thrust force determines a coefficient of friction of 0.7 in this study. The model is validated by comparing the thrust force, torque, and temperature to experimental measurements with reasonable accuracy. The FEM results show that the peak temperature of the workpiece...

...Rodolfo Haber-Guerra; Steven Y. Liang; José R. Alique; Rodolfo Haber-Haber This paper presents the design and implementation of a two-input/two-output fuzzy logic-based torque control system embedded in an open architecture computer numerical control (CNC) for optimizing the material removal rate...

... the rolling deformation of ribbed strip, taking into account friction variation in the roll bite. The calculated results such as the rolling forces, torque, and the rib height of the rolled product while considering friction variation in the roll bite are compared with the measured results obtained from...

... are extended to facilitate the prediction of dynamic cutting forces. Separate thrust, torque, and radial force models for the major cutting edges, secondary cutting edge, and for the indentation zone are formulated. The effects of drill installation errors on the radial cutting forces acting on the chisel edge...

.... An artificial neural network (ANN), using “Torque-versus-Insertion-Depth” signature signals as input, is designed to distinguish between successful and failed insertions. The ANN is first tested using simulation data from an analytical model for screw insertions, and then validated using experimental torque...

...Anish Paul; S. G. Kapoor; R. E. DeVor An oblique cutting model is developed to predict the thrust and torque created by the chisel edge of a drill with an arbitrary point geometry. The chisel edge geometry is modeled using a mathematical representation of the flank grinding parameters and the flute...

... increases, the chips tend to cluster together and clog the flutes, causing increased forces, poor hole quality, elevated drill temperatures, and drill breakage. In this paper, a model for chip evacuation has been developed to predict the force and torque arising from the evacuation of the discontinuous...

...M. Shiraishi; S. Sugano; S. Aoshima To compensate for the effects of coupling torque and load variations experienced in SCARA-type robots, we propose a new method of sensor-based decoupling control. In this method the plant is first nominalized with the use of a disturbance observer...
