The formula used for the moving layer:
P is the power of laser, 8 W in our case.
r_{o} is the radius of laser beam, 0.001 m (1 mm) in our case.
Due to curved surface of the gear in this case, we have to consider motion in all directions. Therefore, r^{2} = (x-x_{o})^{2}+(y-y_{o})^{2}+(z-z_{o})^{2} is the distance of the beam from any point. Here, x, y and z are direction of the global coordinate system respectively. x_{o}, y_{o} and z_{o} are the terms used for defining the motion. In our case,
x_{o} = P_{x0}+(P_{x1}-P_{x0}).t
y_{o} = P_{y0}+(P_{y1}-P_{y0}).t
z_{o} = P_{z0}+(P_{z1}-P_{z0}).t
Where, P_{x0}, P_{y0} and P_{z0} are starting coordinates of the laser beam and P_{x1}, P_{y1} and P_{z1} are ending coordinates.
To get an idea, these points can be found under Geometry Primitives of the simulation.
Can I do this on the curved surface of the cylinder? How can I modify the coordinates?
May be this can help: https://www.simscale.com/projects/ahmedhussain18/circular_welding_analysis/
I want a helical motion on the outside. So it has to move along the axis of the cylinder as well as a circular motion. So I need to use cylindrical coordinate system.
