Abstract

The invention relates to a controllable quick back-forth point feeding grinding system based on a grinding temperature empirical model. The grinding system comprises a high-speed grinding wheel spindle system (1), a spindle power signal real-time collecting and processing system (2), an expert database system (3), a CNC system (4) and a quick back-forth point feeding workbench (5). On the one hand, due to the fact that a grinding wheel retreats in time, too high grinding temperature is avoided, workpiece surface burning and subsurface damage are restrained, and the machining quality of the surface of a workpiece is improved; on the other hand, a clearance generated by retreating of the grinding wheel enables grinding fluid to directly enter a grinding area, the grinding area is effectively cooled and lubricated, blocking and dulling of the grinding wheel are reduced, and it is guaranteed that the grinding process is conducted continuously. Above all, based on real-time feedback of grinding spindle power signals, machining quality is guaranteed in the intelligent, controllable and optimized grinding process, and meanwhile machining efficiency is greatly improved.

Description

technical field

[0001] The invention relates to a controllable fast reciprocating point-feed grinding method based on an empirical model of grinding temperature. The grinding method is designed for high-efficiency deep-cut grinding and profile grinding, and specifically relates to titanium alloys, nickel-based alloys, etc. that are difficult to process. The invention relates to high-efficiency deep cutting of materials and profile grinding of large gears, belonging to the technical field of mechanical grinding. Background technique

[0002] Titanium and nickel alloys are widely used in the manufacture of important components in the aerospace industry, such as jet engine turbine blades and brake disc. The excellent properties of these alloys also make them difficult to machine. It is a very challenging task to process these materials into the desired shape under the premise of ensuring high processing efficiency and surface quality. Grinding with superabrasive abrasive whee...
