Leads

Introduction

This topic explains the options found in the Leads page of the Mill 2 Axis Wizard for the following operations:

 

  • Profile Rough
  • Profile Finish
  • Chamfer Mill
  • Corner Rounding

 

This topic also provides links to related topics.

Leads

Entry

  • Plunge - the tool plunges directly to the start point of the toolpath.

 

 

Type

    • Single Depth - From the Feed Plane, Single Depth will move at the Plunge Feedrate to the full Depth of Cut.

    • Peck - From the Feed Plane, Peck will move at the Plunge Feedrate to the Peck Depth, return to the Feed Plane with a rapid move, rapid down to a point above the last depth equal to the amount of the Feed Plane being used, before continuing to the next Peck Depth amount at the Plunge Feedrate. This method will be repeated until the full Depth of Cut is reached.


      • Peck Depth - sets the increment to use for each peck.

 

    • Fast Peck - From the Feed Plane, Peck will move at the Plunge Feedrate to the Peck Depth, Rapid up to an amount equal the Feed Plane being used, before continuing to the next Peck Depth amount at the Plunge Feedrate. This method will be repeated until the full Depth of Cut is reached.


      • Peck Depth - sets the increment to use for each peck.

         

 

 

  • Ramp - creates a linear ramp move into the stock. The ramps are automatically adjusted, based on values entered, so that collision into the model is avoided. When this option is selected the following boxes become available.

 

Note: The Ramp option is not available in the Chamfer Mill operation.


    • Angle of Approach - sets the angle of the toolpath ramp move. When using this option without defining a Maximum Length, the ramp is applied to the entire profile (from the toolpath start point to the top of feature).

 

 

    • Maximum Length

Select the check box to define the maximum horizontal distance over which the ramp move is applied.

Clear the check box when not limiting the length of the ramp move. The ramp move is created using only the Angle of Approach.

 

 

Warning: The Ramp approach type does not support collision detection or island avoidance. This should be used with caution.

 

 

Lead-in

  • Vertical - generates a plunge feed move into the feature.

 

Warning: The Vertical Lead-in type is not actually a lead-in as it only creates a plunge move into the feature. Most machine controllers cannot apply compensation commands to a vertical plunge (Z-axis) move. (G41/G42 are not output when using the Vertical Lead-in.)

 

  • Parallel - generates a linear feed move into the feature parallel to the toolpath using the specified length.



    • Length - sets the length of the lead-in from the feature.

  • Right Angle - generates a linear feed at a right angle to the toolpath using the specified length.



    • Length - sets the length of the lead-in from the feature.

  • Circular - creates a linear move followed by an arc sweep into the start of the feature. You have complete control over both the line move and the arc move using the following settings.

 

Line

 

  • Right Angle - creates a line segment at a right angle to the arc.

    • Length - sets the length of the line.



  • User Defined - enables the Angle parameter for you to customize the angle of the line.

    • Angle - sets the angle of the line segment.



    • Length - sets the length of the line segment.



  • Tangent - sets the Angle of the line to 0.00 degrees to the arc to make the line and arc tangent.

    • Length - sets the length of the line segment.

 

 

Arc

 

  • Radius - sets the radius of the arc sweep into the start of the feature.

Right Angle User Defined Tangent


  • Sweep Angle - sets the length of the sweep based on the angle of the arc.

Right Angle User Defined Tangent

 

 

  • Blend - generates a linear move and then an arc move into the feature. This lead type can be used to lean-in and lead-out of the feature from the same point. The blend lead type creates a tangent path into the feature.



Line

 

  • Length - sets the length of the line segment.


 

Arc

 

  • Radius - sets the radius of the lead move into the start of the feature.


 

 

Lead-out

  • Same As Lead-in

Select this check box to use the Lead-in settings to automatically set the Lead-out settings.

Clear the check box to set the Lead-out independently from the Lead-in.

  • Vertical - generates a vertical move out of the feature.

 

Warning: The Vertical Lead-out type is not actually a lead-out as it only creates a vertical move out of the feature. Most machine controllers cannot cancel compensation commands to a vertical (Z-axis) move. (G41/G42 are not canceled when using the Vertical Lead-out.)

 

  • Parallel - generates a linear feed move out of the feature parallel to the toolpath using the specified length.



    • Length - sets the length of the lead-out from the feature.

  • Right Angle - generates a linear feed at a right angle to the toolpath using the specified length.



    • Length - sets the length of the lead-out from the feature.

  • Circular - creates an arc sweep followed by a linear move at the end of the feature. You have complete control over both the arc move, and the line move using the following settings.

 

Line

 

  • Right Angle - creates a line segment at a right angle to the arc.

    • Length - sets the length of the line.



  • User Defined - enables the Angle parameter for you to customize the angle of the line.

    • Angle - sets the angle of the line segment.



    • Length - sets the length of the line segment.



  • Tangent - sets the Angle of the line to 0.00 degrees to the arc to make the line and arc tangent.

    • Length - sets the length of the line segment.

 

 

Arc

 

  • Radius - sets the radius of the arc sweep out of the feature.

Right Angle User Defined Tangent


  • Sweep Angle - sets the length of the sweep based on the angle of the arc.

Right Angle User Defined Tangent

 

 

  • Blend - generates an arc move and then a linear move out of the feature. This lead type can be used to lean-in and lead-out of the feature from the same point. The blend lead type creates a tangent path out of the feature.



Line

 

  • Length - sets the length of the line segment.


 

Arc

 

  • Radius - sets the radius of the lead move into the end of the feature.


 

  • Overlap Amount - sets the length of overlap between the start point and end point of the toolpath to change the lead-in and lead-out locations.
