Roughing and Reroughing

Back      Next


Roughing and Reroughing NC Sequences are used specifically for high-speed mold machining. They allow different scanning strategies within single sequence


The topics covered are as follows.

  • Defining a new Roughing NC Sequence
  • Creating a Mill Window within and outside the NC Sequence and specifying its Depth
    Choosing the most suitable toolpath scanning strategy
  • Optimizing the toolpath for high speed machining
  • Eliminating the sudden direction changes with the smooth transition moves
  • Scallop Height control
  • Implementing different scanning strategies within single sequence
  • Defining a new Reroughing NC Sequence
  • Simulation of two sequences in the Vericut simultaneously
  • How to confine the re-roughing to a desired region
