Leads

Introduction

This topic explains the Leads page of the 4 Axis Advanced Rough operation found in the Mill 4 Axis Rotary Wizard.

Leads

Entry

  • Plunge - the tool plunges directly to the start point of the toolpath. The Lead-in and Lead-out settings become available.

 

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.

         

 

 

  • Center Cutting Tool

    - With this check box cleared, you do not have access to the Ramp Entry options.
    - With this check box selected, you have access to the Ramp Entry options.

     

  • Ramp - sets the lead-in motion for the rough toolpath segments (for center cutting tool only). Several ramping strategies are available:

    • Automatic - automatically selects from the following ramp options:Line,Spiral,Zig Zag, andProfileare attempted in this order until a successful ramp entry is accomplished (without gouging).

    • Line - the lead-in move is along an angular line, using theAngle of Approachvalue.

    • Spiral - creates a helical entry into the stock material, the tool engages the stock with helical interpolation. TheRamp LengthandAngle of Approach valuesdefine the helix.

    • Zig Zag - similar to line ramp, the length of the ramp is limited so you get zig and zag angular moves. The zag move is in opposite direction to the zig move and at the same angle to the horizontal. This uses theAngle of Approach and Ramp Length values.

    • Profile - the tool engages the stock following the contour of the part or the toolpath profile.

      • Ramp Length - sets the single segment length for the selected ramp type.

      • Angle of Approach - sets the angle which the ramp move forms with the toolpath segment to which it is connected. This defines the angle of the ramp move to the horizontal.
