Mastercam’s 2D high speed dynamic milling toolpaths utilize the entire flute length of their cutting tools to achieve great efficiency in milling. They are designed to maximize material removal while minimizing tool wear.
This tutorial introduces you 2D high speed dynamic milling toolpath (Dynamic Area Mill) available in Mastercam.
Dynamic Area Mill—
- Machines pockets using one or more chains to drive the toolpath.
- Use Dynamic Area Mill for parts you normally would machine with a Pocket toolpath.
Make a suitable design. I have just made a pocket on a block
- Select Machine Group from the Machine Type on the Menu Bar, and make the stock setup.
- Select 2D High Speed from Toolpaths on the Menu Bar, and name the NC file when prompted.
- Select the desired chain, here I have selected blue chain.
- In Toolpath type we have various dynamic toolpaths, select the Dynamic Area Mill.
- In Tool, select your desired tool from Select library tool. Recommended tool should posses high flute length and min. 4 number of flutes.
- In cut parameters, enter the following parameters.
Recommended stepover is 15 – 30% of tool diameter
Recommended toolpath radius is 10 – 20% of tool diameter
set as 0.5 mm
Since this operation is meant for roughing, we may use roughing tool. So stock has to be left on walls
- In Depth Cuts, uncheck the check box since we don’t use depth cuts.
- In Entry Motion, set desired parameters.
- In Linking Parameters, set retract, feed plane, top of stock and depth.
At the completion of this operation your toolpath looks somewhat like this.
