Surface and Cutline Milling

Back      Next


Surface milling NC Sequence is usually used to semi-finish or finish the shallow surfaces. It is a versatile sequence which can generate a lot of toolpath strategies.


The topics covered are as follows.

  • Defining a new surface milling NC Sequence
    Introduction to different cut definition options to suit the surface topology
  • Choosing the proper scanning strategy
  • Controlling the connection movement between cutting passes
  • Introduction to available entry/exit movements
  • Creating multi-step toolpaths
  • Defining Sloped Mill Surface to classify surfaces based upon slope angle
  • Facing a part with Surface Milling NC Sequence
  • Using OVERTRAVEL_DISTANCE parameter to control the contact of tool with reference model
  • Defining surface milling NC Sequence to finish a hole
  • Controlling the cutting direction
  • Selecting suitable SCAN_TYPE for selected surfaces
  • Introduction to ARC_TANGENT entry/exit condition
  • How to create CL data for a given NC Sequence
  • How to mirror the CL Data
  • Adding Auto Inner Cutlines
  • Adding smooth Entry/Exit motions
  • Adding smooth connection movements between tool passes
  • Inserting a CL Command at the end of CL Data
  • Patterning a NC Sequence
  • Generating CL Data for a patterned NC Sequence
  • Gouge checking patterned NC Sequence

Cutline Machining follows surface topology

I found the tutorials to be very informative both from Software and Manufacturing knowledge point of view.

I really like their "Exercise" style of coaching. Everyone can follow the step-by-step approach. The exercises are quite clear for learning ,and if you have a little experience, in what you want to do, then the tutorials will help you a lot.

I have been in the Moulding Industry since a lot of years and was already familiar with most manufacturing techniques. But there were also some facts which were unknown to me.

I really like their product and will be interested to receive updates if they add more exercises.
