Freyer, Burkhard Heinrich (University of Pretoria, 2016)The studies consist of two simulations of active tool vibration control and tool condition monitoring respectively and a hardware-in-the-loop laboratory demonstration of active tool vibration control typical to ...

Freyer, Burkhard Heinrich; Heyns, P.S. (Philippus Stephanus); Theron, Nicolaas J. (Springer, 2014-06)Signal processing using orthogonal cutting force components for tool condition monitoring has established itself in literature. In the application of single axis strain sensors however a linear combination of cutting ...

Freyer, Burkhard Heinrich; Theron, Nicolaas J.; Heyns, P.S. (Philippus Stephanus); Pickelmann, Lutz A. (Elsevier, 2021-04)This study tests the dual functionality of a piezoelectric transducer for active control of emulated tool vibration. The concept of a self-sensing actuator is here applied jointly with adaptive feedback active vibration ...

Freyer, Burkhard Heinrich; Theron, Nicolaas J.; Heyns, P.S. (Philippus Stephanus) (Sage, 2008)Besides reducing the restricting effects of tool vibrations on productivity, work-piece surface finish and tool life, it is desirable to handle lack of space for sensors at the tool tip and the cost of control systems in ...

Pal, Sukhomay; Heyns, P.S. (Philippus Stephanus); Freyer, Burkhard Heinrich; Theron, Nicolaas J.; Pal, Surjya K. (Springer, 2009-09)One of the big challenges in machining is replacing the cutting tool at the right time. Carrying on the process with a dull tool may degrade the product quality. However, it may be unnecessary to change the cutting tool ...
