刨斜面有两种方法,斜夹正刨和正夹斜刨。斜夹正刨,加工精度低,装夹困难,很少采用。正夹斜刨,加工精度高,定位准确可靠,经常采用。但是,由于标注角度不统一,难免使刀架倾斜的角度出现差错。下面介绍一种快捷的判别方法,见图所示。 刀架倾斜角度的定义:机床纵向铅垂面与待加工斜面的夹角,即刀架丝杠的进给方向与待加工斜面的夹角。 1)当零件图标注的角度是ψ_1,符合定义,刀架直接倾斜ψ_1角即可; 2)当零件图标注角是ψ_2时,倾斜角度为ψ=90°
Planing bevel There are two ways, oblique folder is planing and positive clip diagonal planing. Diagonal folder is planing, machining accuracy is low, clamping difficulties, rarely used. Positive folder oblique plane, high precision machining, accurate and reliable positioning, often used. However, due to inconsistencies in labeling, it is inevitable that the angle of the knife holder tilted wrong. The following describes a quick method of discrimination, as shown. The definition of the angle of the knife holder: the angle between the longitudinal vertical plane of the machine tool and the bevel to be machined, that is, the feeding direction of the lead screw of the knife holder and the bevel to be machined. 1) When the angle of the part icon is ψ_1, in line with the definition, the tool holder can be directly tilted by ψ_1; 2) When the part icon angle is ψ_2, the tilt angle is ψ = 90 °
