With the continuous improvement of service performance requirements of aerospace key components

the difficult-to-cut materials

such as high-performance titanium alloy

nickel-based superalloy

high-strength steel

are widely used in the manufacturing process. Cutting process is the main machining method for these difficult-to-cut materials

whereas the problems should be faced

including the low cutting force

high cutting temperature

severe tool wear

poor machining quality. Recently

researchers have done much work on the prediction and control the cutting force

cutting temperature

tool wear and surface quality in the cutting process. This article systematically reviews the simulation and intelligent control technology of cutting force

cutting temperature

tool wear and surface quality in cutting process of difficult-to-cut materials in aerospace industry

and the problems and challenges are then analyzed. Subsequently

the future development trend of the simulation and control technology on cutting process is prospected.
