Sleeve angle control and precise sleeve matching method

The invention relates to a sleeve angle control and precise sleeve matching method. The method includes the following steps of forming armholes according to a clothes style, wherein h refers to the armhole eye height, B refers to the armhole width, D refers to the chest circumference of finished clothes, and B=D*(22-27%); manufacturing sleeve caps according to the requirements of arm lifting angles of the clothes style, wherein H refers to the sleeve cap height, and H=h*COS(beta); measuring a front armhole arc oa and a rear armhole arc ob; making oa same as a front sleeve upper arc OA, makingob same as a rear sleeve upper arc OB, and then obtaining sleeve width AB, wherein OA and OB are intersected on a horizontal line of the sleeve cap height H; according to the front sleeve upper arc OAand the rear sleeve upper arc OB, copying a new sleeve cap line; according to the diameters of the sleeve widths of different clothes styles, the chest circumference of the finished clothes and the arm lifting angles, calcula
