Paper Abstract

To increase the flexibility of the generative LAPS-J (laser aided power solidification -- powder jet) process, a special focusing device has been developed. The beam of a Nd:YAG laser is delivered into the production machine via a step-index glass fiber. To utilize the resulting top-hat intensity distribution, the end facet of the fiber is imaged on the workpiece by a special optical system, consisting of four lenses. It allows the variation of the scale of imaging between 4:1 and 1:1. By the computer controlled movement of two motors it is possible to change the width of the generated tracks in this range during laser processing. Integrated in a turning center, the LAPS-J proces allows new and complex applications, e.g. in the fields of cladding, rapid prototyping or repairing of metal parts. With an additional process control, the quality and accuracy of generated metallic parts can be considerably increased.
