1Reliability
If a conventional transportation plate is used in a laser beam machine, then the plate can transport dross, but the plate experiences significant thermal deformation and compressive plastic strain
Solution Approach 1:
The transportation plate is designed with non-uniform thickness, where the thickness varies in the laser beam irradiation direction. Specifically, the plate has a first thickness in a first region and a second thickness in a second region, with the second thickness being greater than the first thickness. This local variation in thickness compensates for the thermal deformation caused by laser irradiation, reducing the overall deflection of the plate while maintaining its ability to transport dross.
2Object-affected harmful factors
If the transportation plate is made thicker to reduce deflection, then thermal deformation decreases, but the plate weight and device complexity increase
Solution Approach 1:
Instead of uniformly increasing the plate thickness throughout, the invention applies increased thickness only in specific regions (the second region with greater thickness) where it is most needed to counteract thermal deformation. This localized thickening approach reduces deflection effectively while minimizing the additional weight compared to a uniformly thick plate.
Solution Approach 2:
The invention addresses the deflection problem by introducing a dimensional variation in the thickness parameter along the laser beam irradiation direction. Rather than simply making the plate thicker everywhere (one-dimensional solution), the thickness is varied continuously or in steps along the length of the plate, creating a gradient structure that optimizes stiffness where needed while minimizing overall mass.

AI summary
A method for designing a transportation plate for transporting dross includes the steps of: acquiring a basic deflection amount, in a case where a model plate is defined as a basic model of the transportation plate that transports the dross generated by irradiation of a laser beam on a workpiece from a laser beam machine apparatus and the basic deflection amount is defined as an amount of deflection of the model plate, the deflection occurring due to irradiation of a first laser beam on the model plate; and designing the transportation plate based on the model plate for a first deflection amount to be smaller than the basic deflection amount, in a case where the first deflection amount is defined as an amount of deflection of the transportation plate, the deflection occurring due to the irradiation of the first laser beam on the transportation plate under a substantially identical condition to a condition for the irradiation of the first laser beam on the model plate.
