Abstract

The invention discloses a powder laying precision compensation system and a powder laying precision compensation method used for rapid forming equipment. The powder laying precision compensation system comprises a powder laying device disposed on the bottom plate of the rapid forming equipment and a control host used for the control and the compensation of the elevating of the powder laying device. The powder laying device comprises an optical axis, a powder layer elevating working bench, and an installation plate used for installation of optical axis elevating driving mechanism. The powder laying precision compensation method comprises steps that 1, the elevating clearance value of the optical axis elevating driving mechanism is acquired; 2, the rising path of the optical axis elevating driving mechanism is controlled, 201, the rising of the optical axis elevating driving mechanism is initialized, 202, the rising of the optical axis elevating driving mechanism is compensated, 203, the falling of the optical axis elevating driving mechanism is calibrated; 3, the elevating working distance of the powder layer elevating working bench is set; 4, the elevating of the powder layer elevating working bench is controlled. The rising process of the optical axis elevating driving mechanism is ended by a falling state, and the calibration of the optical axis elevating driving mechanism from the rising state to the falling state is reduced, and the operation precision and the operation reliability of the powder layer elevating working bench are improved.

Description

technical field [0001] The invention belongs to the technical field of motion precision compensation of a powder spreading mechanism of rapid prototyping equipment, and in particular relates to a powder spreading precision compensation system and method for rapid prototyping equipment. Background technique [0002] In rapid prototyping technology, using powder as raw material, the rapid prototyping technology of parts through selective deposition / sintering / melting process is a hot spot in the field of rapid manufacturing. The existing selective sintering technology completes the processing of parts by layered scanning . During the processing, every time a layer is processed, the powder spreading workbench is lowered by a certain distance, the powder feeder sends out a certain amount of powder, and then the powder spreading mechanism flattens it, and then the layer of powder is sintered, and this process is repeated continuously. A process, and finally complete the processin...
