Trajectory Milling

Back      Next

 

Trajectory milling is a 3 to 5 axis milling sequence. It allows to sweep a tool along any user-defined trajectory. It gives the user very low level control over the tool path.

Contents

The topics covered are as follows.

  • Defining a Composite datum curve
  • Defining a 2-Axis trajectory milling NC Sequence.
  • How to perform 2-Axis multi-step trajectory milling
  • How to perform 2-Axis multi-pass trajectory milling
  • Defining a 3-Axis trajectory milling NC Sequence.
  • Adding smooth entry/exit motions.
  • Checking the gouges against reference part.
  • Shifting the toolpath upward to avoid gouging by using AXIS_SHIFT parameter
  • How to perform 3-Axis multi-step trajectory milling.
  • Machine a slot in multiple steps
  • Controlling the connection movement between slices by CONNECTION_TYPE parameter
  • Machining a slot (groove) which lies on a curved surface
  • Face a part by a succession of trajectory passes

Testimonials

"We purchased both of the tutorials about a month ago, and I have to say I was skeptical because they were considerably less expensive compared to the other available tutorials that I found.  We had one of our CNC programmers and our lead mold designer evaluate them before we used these to train two new employees.  Both engineers had very good things to say about the tutorials.  Each said they learned or remembered things they hadn't used in a while and that the time they spent going through these was well spent.  I have to admit I can't wait for this company to produce some more generic tutorials on modeling, assembly, surfacing, etc.  In my opinion these tutorials represent a good value.  I hope they're able to continue to produce good material and keep their prices in check."
