Abstract

The invention discloses a titanium alloy casting pouring riser cleaning process based on an industrial robot. The machining process comprises the steps of distance measuring, cutting, rough grinding and semi-finishing grinding. After these steps, a titanium alloy casting riser can be cut and ground to be flush with the plane of the root of the titanium alloy casting riser, and the surface with lower roughness can be obtained. The riser removing efficiency can be greatly improved, residual stress is reduced, burn is prevented, the roughness of the surface of a machined workpiece after processing and the consistency after rise removing can be ensured, and the titanium alloy grinding process is more perfect.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to a riser cutting process, in particular to a process for cleaning the riser of titanium alloy castings based on an industrial robot. Background technique [0002] Titanium alloy has high specific strength and good heat and corrosion resistance. It is a light-weight high-temperature structural material and has been widely used in military fields such as aviation, navigation, chemical industry, and weaponry. Net-shaped structural parts reduce production costs, and the application ratio accounts for more than 90%. The removal of the riser of cast titanium parts is one of the main processes in the processing of titanium alloy parts. Since titanium alloy is a difficult-to-machine material, there are problems such as large grinding force, high grinding temperature, and serious adhesion of the grinding wheel during processing. , these problems seriously restrict the efficiency of grin...
