This book explains the challenges and advancements in cutting precise cylindrical shapes on
difficult materials through spark erosion. Titled Spin while Burn it addresses the drawbacks
associated with this process including unsatisfactory surface finish and limited productivity.
Despite utilizing advanced computing and statistical optimization methods achieving the ideal
balance between material removal rate (MRR) and surface quality remains elusive. In response
the book introduces a hybrid ultrasonic-assisted approach in the wire electrical discharge
turning (WEDT) process. By integrating a rotating workpiece with ultrasonic vibration the
authors evaluate its impact on MRR and surface finish. Through meticulous design experiments
and statistical analysis they explore various cutting parameters and machining paths. The book
highlights the characterization of machined surfaces through elemental analysis and surface
morphology evaluations. The results demonstrate the positiveeffects of integrating ultrasonic
vibration into WEDT even without optimized ultrasonic parameters. By reducing electrode wire
debris and employing multi-objective parameter optimization using the genetic algorithm
significant improvements are achieved in MRR and surface roughness compared to conventional
WEDT. Spin while Burn consists of five chapters delving into the challenges history
principles performance and future perspectives of the Spin-while-Burn process in
manufacturing. This comprehensive book offers valuable insights into enhancing surface quality
and productivity in the cutting of precise cylindrical shapes on challenging materials through
spark erosion.
