Seminar – Dr. Yusuf Altintas: Digital Machining

Digital Machining

Speaker: Dr. Yusuf Altintas

Professor UBC Mechanical Engineering. Director of the Manufacturing Automation Laboratory (MAL) and NSERC – P&WC- Sandvik Coromant Industrial Research Chair Professorship to develop next-generation Digital Machining Twin Technology.

Location: CEME Building (6250 Applied Science Lane), room 1203

The Department of Mechanical Engineering’s Distinguished Colloquium series invites leading researchers to share their expertise on a variety of topics with our academic community.


Our research aims to develop mathematical models of metal cutting operations, machine tool vibrations, and control. The science-based digital models allow the virtual design of machine tools; simulation, optimization and online monitoring of machining operations.  The model predicts the cutting forces, torque, and power consumed in machining parts by considering material properties, cutter geometry, structural flexibilities, and cutting conditions along the tool path. The dynamics of servo drive control systems and trajectory generation of machine tools are considered. An in-house developed virtual and real-time CNC system allows the design and analysis of any five-axis machine tool controller. The virtual machining system simulates the process and adjusts the federate along the tool path in the CAM environment. The system is also used for online monitoring and control of machine tools and the machining process by communicating with CNC in real time as a digital twin. The presentation will cover the overview of fundamental research we conducted at our laboratory and its application in industry.


Professor Altintas obtained his Bachelor’s from Istanbul Technical University (1975), M.Sc. (1980) from the University of New Brunswick and Ph.D. (1987) from McMaster University in Canada. He worked as a machine tool manufacturing engineer in Turkey (1977-1978),  process development engineer in Pratt & Whitney Canada in Montreal (1980-1981), and served as the principal engineer of the Canadian Institute of Metalworking at McMaster University in Hamilton (1981-1982). He joined The University of British Columbia and founded Manufacturing Automation Laboratory in 1986. He conducts research on metal cutting, machine tool vibrations, control, sensors and actuators for machine tools, and virtual machining. He has published over 200  archival journal and 100 conference articles with over ~38,000 citations with an h index of 100 (Google Scholar), and a widely used “Manufacturing Automation: Principals of Metal Cutting Mechanics, Machine Tool Vibrations and CNC Design. 1st ed. 2000, 2nd ed.:2012 with Chinese (2003,2020) and Turkish (2017) Editions. His research laboratory created advanced machining process simulation (CUTPRO), virtual part machining process simulation (MACHPRO) and open-modular 5-axis CNC system (Virtual CNC), which are used by over 300 companies and research centers in the field of machining and machine tools worldwide.

Professor Altintas is a fellow of Royal Society of Canada, National Academy of Engineering (USA), CIRP, ASME, SME, ACATECH, CAE, EC, Tokyo University, P&WC, AvH and ISNM. He received Pratt & Whitney Canada’s (P&WC) university partnership (1997), APEG BC’s Meritorious Achievement (2002), APEG BC R.H. McLachlan (2010), UBC Killam Teaching Prize of Engineering (2011), Gold Medal of Engineers Canada (2011), SME Albert M. Sergent Progress Award (2012), NSERC Synergy Award, ASME Blackall Machine Tool and Gage best journal paper award, the special scientific award of the Republic of Turkey in Science and Engineering (2013), Georg Schlesinger Production Engineering Award (Berlin, 2016), and ASME William T. Ennor Manufacturing Technology Award (USA, 2016). He holds Honorary Doctorate Degrees from Stuttgart University (2009) and Budapest University of Technology (2013), and holds an Honorary Professor title from BEIHANG University in Beijing. He was the past president of CIRP (International Academy of Production Engineering Researchers) for the term 2016 – 2017. He is designated as the Distinguished University Scholar at the University of British Columbia (since 2017). He is the founding coordinator of Mechatronics Option and was cofounder of the Manufacturing Engineering Degree program at UBC.

He directed NSERC CANRIMT Machining Research Network across Canada (2010-2022), and holds the NSERC – P&WC- Sandvik Coromant Industrial Research Chair Professorship to develop next-generation Digital Machining Twin Technology (since 2002). He is also founding president of MAL Manufacturing Automation Lab. Inc. ( which develops virtual machining technology.
