Angle From Curve

Introduction

This topic will explain Angle from curve, describe where to find it, and will provide an example.

Angle from curve

Angle from curve allows a fixed tilt angle to be added to the tool orientation from the user defined curve. The curve must be located above the drive surface. The system creates the tool orientation by connecting each toolpath point on the drive surface to the closest point on the tilt curve.

 

Important: Make sure that your tilt curve is located above your drive surface. The tools maximum tilting is 90 degrees (vertical) or 0 degrees (horizontal). So if your tool axis is already tilted 35 degrees from the present toolpath point to your curve and you set a fixed tilt angle of -60 degrees, the tool will only tilt 0 degrees (horizontal).

 

The following image shows (1) the selected Tilt Curve and (2) the resulting tool axis orientation at various points on the drive surface.

To access Angle from curve: 

 

• The Angle from curve option can be found on the Tool axis control page with Tool axis will... set to either: 
  
  
  • Tilted through curve
    
    
  • Tilted from curve away
    
    
• With one of these selected for Tool axis will... the option can be found in the drop down list next to Curve tilt type.

Example

• The example shows a curved surface with a certain radius. The tilt curve is placed above. It has the same shape as the surface but a smaller radius. Look at the tool axis orientation at the end of the curve. The tool goes through that point because it is the closest one when you look from the top (second image).

 

 

 

 

• When you tilt the tool 10 degrees, you get this result.
