Evaluation of infeed strategies for turning of large thread profiles
Апстракт
Several infeed strategies for multipass threading operations on CNC lathes are well known and they are
implemented in form of apropriate canned cycles in system software of CNCs. These strategies are especially
suitable for triangular profiles of thread. Paper presents method developed for analysing of infeed strategy in
threading operations for arbitrary geometry of thread profile and geometry of tool profile, including trapezoidal
threads and worm wheels. Proposed method uses two criteria for evaluation of specific infeed strategy in multipass
turning of threads. The first one is the measure of balance of uncut chip area in subsequent passes (implemented
application in Matlab is described). Calculation of chip area is based on numerical integration The second criterion
is referred to predicion of cutting forces and their distibution in subsequent passes.. Cutting force estimation is
based on specific cutting forces and engaged chip area acting on discretized lenghts of cuttin...g edges.
