Abstract

The invention relates to the technical field of numerical control machining, in particular to a flexible speed planning and displacement compensation method for laser cutting, which comprises the following steps of: firstly, constructing a high-order continuous derivable acceleration function model and a high-order continuous derivable deceleration function model; according to the obtained acceleration function model and the deceleration function model, obtaining a corresponding acceleration displacement calculation function model and a deceleration displacement calculation function model; obtaining a total calculation displacement value of the corresponding motion section according to the total interpolation period; and calculating a difference value between the to-be-planned displacement value and the total calculated displacement value according to a rule to obtain a minimum displacement compensation unit value. The speed function construction method provided by the invention has a high-order continuous derivable characteristic, by combining with a displacement compensation method, strong vibration or track distortion cannot be brought to the machine tool while accurate movement displacement is ensured, the requirements of flexible movement and smooth cutting of the machine tool can be met, and compared with a traditional speed planning method, the speed planning method provided by the invention has the advantages that the speed planning efficiency is improved. The method has the advantages of simple process and efficient execution.
