Products, Processes and Systems Engineering Laboratory (LIPPS)

Established in 1998, the Products, Processes and Systems Engineering Laboratory, which comprises more than 95 members, is a leader in its sector in Canada. LIPPS conducts research aimed at creating, validating and optimizing products, processes and manufacturing systems, focusing on a multidisciplinary approach that incorporates mechanical engineering, software engineering and industrial engineering concepts.

LIPPS stands apart because of its approach, which combines applied research with industrial development activities.

Research

Research at LIPPS revolves around two complementary axes in modern industry.

Axis 1: Physical domain (materials, tools, processes)

Optimization of manufacturing processes (machining, welding, grinding, rapid prototyping, moulding and numerically controlled machining)
High-speed machining and clean machining (environmentally friendly machining that respects workplace safety standards)
Instrumentation and control of processes and products (non-destructive control)
Automatic metrology and inspection (CMM, post-processor, vision and laser scanner)
Materials characterization
Recycling and reuse of materials
Tool life and machinability testing
Materials and composites processing

Axis 2: Virtual domain (CAD/CAM, digitization and optimization of manufacturing processes)

Design for efficient manufacturing and assembly
Integrated engineering methods, models and tools (CAD, CAM, FE, integrated technical data management)
Dimensional and geometric variation management (tolerancing, planning sheets, process capabilities)
Product lifecycle management and engineering change management
Design of experiments (DOE), statistical data analysis and optimization
