Abstract:

In order to improve the programming accuracy and eficiency during the NC machining process by toothbrush-hair-planting machines,a hole-position image of the toothbrush head was firstly obtained with the help of a scanner.Then,based on the image identification technique,the data processing technique and the platform of Visual C + +.NET.a program of the NC machining by toothbrush-hair-planting machines was generated.This process
includes the aspects of image inputting,edge position limitation of the image,median filtering,outline distillation,image regularity and calculation of the hole parameters.The experimental resuhs show that the proposed method is feasible and effective,with a precision that can meet the production requirements.It can be used to locate the hole position accurately and rapidly,thus lessening the time cost of the supplementary machining.

Key words: toothbrush-hair-planting machine, NC machining, hole-position image identification
