Keynotes and Workshop Speakers

Workshops Sessions

Session 1: Digital Machining

Speaker: Prof. Yusuf Altintas, UBC

UBC MAL developed a set of digital machining software tools which are widely used in aerospace, machine tool, cutting tool, die and mold, automotive and general machining industry. This workshop will explain the tap testing of the machine tools; prediction of chatter-free cutting conditions for process planners; troubleshooting vibration problems; simulation of force, torque, power, vibration and surface form errors; and optimization of NC programs in virtual CAM environment. Sample machining cases will be presented in partnership with Sandvik Coromant.

Session 2: Metrology

Speaker: Prof. Rene Mayer, Polytechnique Montréal

Five-axis machine tools are increasingly used within automated production cells. Their high cost and high productivity mean that any production interruption, such as to diagnose part quality issues, especially when unplanned, causes significant production loss and cost. The workshop will describe the various errors sources affecting machine tools, as per IS0230-1:2012, including errors occurring with each axis (intra-axis errors such as out-of-straightness) and those between axes (inter-axis errors such as out-of-squareness). These errors combine to affect the location of the tool with respect to the workpiece (volumetric errors), that directly impacts the machined part geometric quality. The automatic monitoring of these errors is facilitated by using the touch trigger probe that almost all CNC now have. Its use for machine geometry diagnostic through the SAMBA method will be illustrated with application examples.

Session 3: Machining Innovations

Speaker: Prof. Phil Koshy, McMaster University

Science-based conception and development of innovative processes continue to shape the evolution of machining technology, leading to significant advances. The workshop will focus on recent developments in this light and will emphasize the creative aspects of research on cutting, grinding and electrical discharge machining processes. Novel machining techniques, tooling concepts, test and measurement methods, and process monitoring schemes will be presented.
