Abstract. The issue of improving a laser head housing design to ensure its portability with the account for capabilities of additive equipment, allowing to manufacture parts of the housing of high complexity out of plastic, is covered. Manufacturing the laser head housing of plastic makes it possible to reduce its material consumption as compared with housing made of aluminum alloy D16. It is proposed to further reduce the material consumption of the plastic housing by introducing special pockets and stiffening ribs into its design. A comparative analysis is performed in CAE-module of CAD/CAM-system SolidWorks to examine the strength and rigidity of the design options for the body, assembled from parts with the pockets and stiffeners, as well as without them. Results of modeling the deformation process show that it is possible to replace the material of aluminum alloy housing parts with plastic and that a decrease in material consumption and a change in the housing design do not lead to a loss of its strength and rigidity, which causes an unacceptable deviation of the laser beam from the vertical, i.e. does not affect the operation of the laser head. It is proposed to introduce such a laser head into a vertical machining center so that, along with traditional methods of processing workpieces from various materials, a wider range of different types of laser processing is available by cutting. This will allow not only to expand the technological and functional capabilities of such equipment with numerical control and reduce the time of production, but also to improve the technological, accuracy and functional characteristics of the manufactured product.
