Volume and Local Milling

Back      Next

 

Volume milling is the mostly used NC Sequence while machining a part. So it is given its due share in our tutorials.

Contents


The topics covered are as follows.
  • Defining a new Volume milling NC Sequence
  • Controlling the cutting condition at corners to avoid vibration
  • Specifying the linear ramp motion instead of plunge
  • Specifying the helical ramp motion
  • Controlling the cutting feed along ramp motion
  • Simulating toolpath in Vericut for verification
  • Specifying an axis for plunge motion to the next slice
  • Defining a Local Milling NC Sequence for rest milling operation
  • Using Volume Milling for profiling of the walls of the mill volume
  • Controlling the entry/exit condition of the tool
  • Controlling the surface finish by specifying scallop or cusp height
  • Performing profiling and facing within a single NC Sequence by using pocketing strategy of Volume Milling
  • Customization of the toolpath
  • How to copy a NC Sequence and specify new references
  • How to use excluded surfaces option to exclude the selected surfaces from profiling
  • How to control the entry/exit into cut for longer tool life and less machine tool acceleration/deceleration
  • Introduction to the following entry/exit movements between slices
        1: Lea in, Lead out
        2: Ramping
        3: S-shape Connections
  • Defining a local milling NC Sequence to machine the material left at corners by a previous tool
  • Facing a part's top surface with Volume Milling
  • Defining a Mill Window
  • Specifying Tool Side for Mill Window
  • Machining the part with Slice by Slice strategy
    Declaring Approach Walls for a Mill Volume
  • Offsetting the selected surface of a Mill Volume
  • Introduction to Smart retract option
  • Introduction to Top Surfaces functionality

 

 

Roughing a Cavity- Helical Entry and Minimum Corner Radius Control to Avoid Vibration at Corner

 

Pocketing- Profiling of Walls and Facing of Horizontal Surfaces within a single NC Sequence

 





Profiling- Finishing of Steep Walls with "S" Connection, Tool Stays in Constant Contact



Local Milling- Machining the material left by previous tool

 

 



High Speed Facing- Single Entry/Exit, "S" Connection between Passes, Corner Rounding







Thin Wall Structure







Machining of Thin wall component with Slice by Slice Scanning







Smart Retract- Minimizes the time wasted in Retract and Plunge movements






Mill Window requires less references to select

Testimonials

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.
