Feed & Spin [M]


This tab enables you to define the feed, spin, Machining Level and Max. Chip Thickness for the tool chosen.  

The units (Metric/Imperial) are selected according to the CAM-Part units chosen while creating the a CAM-Part. These units are suppressed and cannot be changed.

Feed Units

The Feed values can be displayed in the following two types of units:

  • F is the default type displaying units of distance per time.
  • FZ displays the equivalent values in units of distance per tooth, which are calculated according to the formula FZ = F/(Number of flutes × S).

Feed  

This section defines the feed rate of the tool

  • Feed XY - Feed rate in the XY plane.
  • Feed Finish XY - Feed rate used for finish milling. The Feed finish XY check box enables you to optionally define different values for Feed XY. When this check box is selected, the corresponding edit box is available so that you can edit its value. When this check box is not selected, the specified Feed XY value is used for both rough and finish machining.
  • Feed Z - Feed rate in the Z direction.
  • Feed Z for penetration only - When this check box is selected, the defined Feed Z is used only for vertical movements. When this check box is not selected, the defined Feed Z is used for all movements when the Z-coordinate changes.

This option is available for End Mill, Bull Nose, Ball Nose, Face Mill, Taper, Taper Ball Nose, Engraving, Lollipop, Centre Drill and Spot Drill tools.

  • Feed Link, % - feed rate used for tool path linking movements.

  • Feed Lead In/Out, % - feed rates used for approach and retreat tool movements.

Spin Units

The Spin values are displayed in the following two types of units:

  • S is the default type displaying revolutions per minute.
  • V displays the equivalent values for material cutting speed (velocity between the edge of the cutting tool and the surface of the workpiece), which are calculated according to the formula V = (S × π × Diameter)/1000 for Metric units and V = (S × π × Diameter)/12 for Metric units.

Spin

This section defines the spinning speed of the tool by the following values:

  • Spin rate - normal spin rate; used in rough milling.
  • Spin finish - finish spin rate; used in finish milling.

The Spin finish check box enables you to optionally define different values for Spin rate and Spin finish. When this check box is selected, the corresponding edit box is available so that you can edit its value. When this check box is not selected, the specified Spin rate value is used for both rough and finish machining.

The Spin direction section enables you to choose between the clockwise (CW) or counterclockwise (CCW) direction.

Machining Level

Machining level enables you to assign a level different than the CAM-Part default that is specific to each Tool Item.

Max. Chip Thickness

Max. Chip Thickness is automatically calculated by the Technology Wizard, but you can instead specify a preferred value that is associated to the Cutter (e.g., that which is recommended by the tool manufacturer for the given type of Cutter Material).

Because this value is automatically calculated according to several factors, it is recommended not to specify a Max. Chip Thickness for any given tool.
