This article concerns the application of topological optimization with numerical methods in the ABAQUS system of machine parts on the example of a laser cutter gate. The gate structure was optimized with the initial mass of 566 kg, assuming that the gate deflection is less than the permissible displacements and the reduced stress are lower than the allowable stresses. It has been shown that the optimal construction of the gate has a mass of 28.1 kg. In addition, the new gate can be made from one sheet of sheet metal using a simple laser cutting method.
