Creep Feed Profile Grinding Of Ni

Creep feed grinding is a special grinding strategy where considerable material removal rates and high surface qualities are attained along with quite low grinding wheel wear. It was applied in the early 1950s for the first time and lead to an extensive development of machines, grinding

Creep feed profile grinding (CFPG) as a crucial precision process that is applied to produce the final profile of the blade tenon. However, sudden surface burns and microcracks of machined γ-TiAl blade tenon often occur because of its low plasticity and high strength during grinding processes, leading to poor surface integrity.

and deep forms [2]. Creep-feed grinding has been used as early as high-speed grinding, dating back to mid-1960s. In creep-feed grinding, low workpiece speeds and large depths of cut are used. Typical creep-feed workpiece speeds are lower than 60 mm/ min [3]. In the early 1990s, however, HEDG emerged as a process that increased the efficiency of ...
