Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to a high-precision military sand table rapid prototyping device and method. Background technique [0002] The military sand table has the characteristics of strong three-dimensional sense and intuitive image. It can accurately display the terrain of the theater, indicate the composition of the enemy's position, the deployment of military forces, and the configuration of weapons. all play an important role. [0003] Modern military behavior has higher requirements for sand table production, which are mainly reflected in two aspects: [0004] The first is high dimensional accuracy. For example, the location deployment of howitzers and bunkers needs to fully consider many factors such as their range, surrounding terrain, and shell trajectory, and requires high precision in the size of the sand table. [0005] The second is that the production time should be shor...
