Lays down the diemnsions of these cutters with plain parallel or parallel flatted shanks. The cutters are particular intended for directly obtained clearances of moulds, patterns and dies, when these exceed 2 52'. Applies to flat-end cutters and ball-nosed cutters. There are short type, medium type, and long type cutters.
Abstract
Overview
ISO 3940:1977 is an international standard published by the International Organization for Standardization (ISO) that specifies the dimensions for tapered die-sinking cutters with parallel shanks. These specialized cutting tools are primarily used for creating precise clearances in moulds, patterns, and dies, particularly when those clearances exceed an angle of 2° 52'. The standard covers cutters with plain parallel shanks as well as those with parallel flatted shanks. ISO 3940:1977 includes dimensional guidelines for both flat-end and ball-nosed cutters, available in three types based on length: short, medium, and long.
