An in-situ Inverse Projected-Fringe system for on-machine inspection of axisymmetric parts is developed. Parts considered for this study are specular with RMS surface roughness >1 μm and have large slopes with radii of about 50 mm. The in-situ syste

This paper describes a new approach for parameterizing friction models. Velocity measurements of a spring-mass-damper oscillator with a friction contact are used to determine the Coulomb friction coefficient for the friction-based energy dissipation.

This paper details frequency response function (FRF) measurement and simulation for a dynamic oscillator with a sliding (Coulomb) friction contact. The oscillator is approximated physically using the friction measuring machine (FMM), a parallelogram

The objective of this paper was to conduct a study of the multi-level multi-variable design space in titanium machining through high performance computing (HPC) simulations that was otherwise too vast to be explored by physical experiments alone. For

In single-point metal turning and boring processes, a chip nest can often be created that is a hazard to part and operators alike. In order to mitigate this, a process called modulated tool path (MTP) machining was developed that superimposes a sinus

A post-processing algorithm for CNC machine NC code was developed for altering NC code based on measurements from a stand-alone coordinate metrology system that measures the orientation and offset of the part and machine coordinate systems (CS). With

Complex metal parts produced by additive manufacturing processes are often very difficult to dimensionally characterize by traditional contact and non-contact metrology systems. The most efficient and effective approach to measuring metal additively

The modulated tool path (MTP) chip breaking process has been modified to improve chip management capabilities and to prevent large chip nest accumulations commonly encountered in threading operations. The use of MTP to create segmented chips requires

An analytical time domain model is developed to predict the motion of a multi-mode cutting tool during orthogonal turning operations. This model is an extension of a single mode model that finds the solution to the governing delay differential equati
