Worked Example

Verified calculation

Given:

  • Lens Focal Length = 0.15
  • Laser Cutting Head Standoff Distance = 0.0025
  • Beam Waist Axial Position Relative to Focal Plane = 0
  • Beam Divergence Half-Angle at Waist = 0.001

Expected Result:

  • Defocus-Induced Kerf Taper Angle (Half-Angle) = 8.3333333331404E-6

Engineering Interpretation:

Under the given input conditions, the calculated result is: Defocus-Induced Kerf Taper Angle (Half-Angle) = 8.3333333331404E-6 rad.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

Half-Angle = atan(0.5 * beam divergence half-angle at waist * abs(laser cutting head standoff distance - beam waist axial position relative to focal plane) / lens focal length)
