Feature top fillet milling

Use the Feature top fillet milling page to specify the cutting range in the axial and radial directions of the tool.

Axial

Multiple cuts are generated along the axial direction.

Extent — Select how to calculate the limits of multiple passes.

• Number of cuts — Enter a number to limit the number of passes.
• Top fillet extent — Machine the total height of the fillet.
• Stock extent — Machine the distance between the tool start position and the end of the block.

Extra depth — Specify an extra distance above and below the fillet for your toolpath range.

Note: This option is only available for when you select an Extent of Top fillet extent.

Stepdown — Enter the maximum distance between successive passes.

• Copy stepdown from tool — Click to load the axial depth of cut from the active tool's cutting data. The axial depth of cut is measured along the tool axis.
• If you enter the value manually, the button changes to .
  Note: These options are only available when you select an Extent of Top fillet extent or Stock extent.

Tool position — Select the position of the tool relative to the fillet.

• Top axial depth — The distance the tool extends above the top of the fillet.
• Bottom axial depth — The distance the tool extends below the bottom of the fillet.
• Gauge diameter — The effective tool diameter at the contact point of the tool on the fillet.
Note: These options are only available when you select an Extent of Number of cuts or Stock extent.

Radial

Multiple cuts are generated along the radial direction.

Extent — Select how to calculate the limits of multiple passes.

• Number of cuts — Enter a number to limit the number of passes.
• Chamfer extent — Machine the total height of the fillet.
• Stock extent — Machine the distance between the tool start position and the end of the block.

Extra width — Specify an extra distance radially around the fillet for your toolpath range.

Note: This option is only available for when you select an Extent of Top fillet extent.

Stepover — Enter the distance between successive area clearance passes at a single Z height.

• Copy stepover from tool — Click to load the radial depth of cut from the active tool's cutting data. The radial depth of cut is measured normal to the tool axis.
• If you enter the value manually, the button changes to .
  Note: These options are only available when you select an Extent of Top fillet extent or Stock extent.

Other options

Tolerance — Enter a tolerance value to determine how accurately the toolpath follows the feature.

Cut direction — Select the milling technology.

Select a Cut Direction from the following:

• Climb — Select to create toolpaths using only climb milling, where possible. The tool is on the left of the machined edge when viewed in the direction of tool travel.

  

• Conventional — Select to create toolpaths using only conventional or upcut milling, where possible. The tool is on the right of the machined edge when viewed in the direction of tool travel.

  

• Any — Select to create toolpaths using both conventional and climb milling. This minimises the tool lifts and tool travel.

Thickness — Enter the amount of material to be left on the part. Click the Thickness button to separate the Thickness box in to Radial thickness Axial thickness . Use these to specify separate Radial and Axial thickness as independent values. Separate Radial and Axial thickness values are useful for orthogonal parts. You can use independent thickness on sloping walled parts, although it is more difficult to predict the results.

Radial thickness — Enter the radial offset to the tool. When 2.5-axis or 3-axis machining, a positive value leaves material on vertical walls.

Axial thickness — Enter the offset to the tool, in the tool axis direction only. When 2.5-axis or 3-axis machining, a positive value leaves material on horizontal faces.
