In manufacturing, an undercut is a special type of recessed surface that is inaccessible using a straight tool. In turning, it refers to a recess in a diameter generally on the inside diameter of the part. In milling, it refers to a feature which is not visible when the part is viewed from the spindle. In … Zobraziť viac On turned parts an undercut is also known as a neck or "relief groove". They are often used at the end of the threaded portion of a shaft or screw to provide clearance for the cutting tool. Zobraziť viac Undercuts from etching (microfabrication) are a side effect, not an intentional feature. Zobraziť viac Undercut - Any indentation or protrusion in a shape that will prevent its withdrawal from a one-piece mold. Zobraziť viac In milling the spindle is where a cutting tool is mounted. In some situations material must be cut from a direction where the feature can not be seen from the perspective of the spindle and requires special tooling to reach behind the visible material.

The Euro dust cup design is another method of dust cup retention that has a tighter seal for better prevention of lubrication leaking out. Bakelite relief is designed with a sharp relief to assist in removal of granulations along the die wall. WebUndercutting Cut Style These end mills have a long shank and a cutting edge that curves around the top of the ball end, allowing them to reach into pockets to create undercuts. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. ipcrf pictures
