Abstract

The invention discloses a low-temperature drilling device of resin-based fiber reinforced composite material and a method thereof. The low-temperature drilling device consists of a low-temperature cooling device, a temperature control device, a cutting force measuring device and a processing unit. A resin-based fiber reinforced composite material laminated plate is drilled under a low-temperature environment, so that the defects of layering and burrs in the drilling of the resin-based fiber reinforced composite material laminated plate are reduced, and the drilled surface quality of the resin-based fiber reinforced composite material laminated plate is improved; and the optimal low-temperature drilling parameters are adjusted through measuring and estimating the cutting force.

Description

technical field [0001] The invention belongs to the technical field of processing resin-based fiber-reinforced composite materials, and in particular relates to a low-temperature drilling processing device and method for resin-based fiber-reinforced composite materials. Background technique [0002] With the widespread application of resin-based fiber-reinforced composite materials, the demand for secondary machining is increasing, especially when composite materials are assembled and connected with other parts, a large number of drilling processes are unavoidable. When processing in a normal temperature environment, due to the anisotropy of the resin-based fiber-reinforced composite material, the interlayer strength is low, and the hardness is high, the strength is high, the thermal conductivity is poor, and the resin matrix is ​​easily polluted by cutting fluid. It is a typical difficult-to-machine material. A large number of experiments have shown that when processing re...
