Online panel cutting optimization software. generate optimized cutting patterns based on the available stock sheets by nesting the required parts.
The depth of cut is the distance that the tool bit moves into the work. usually measured in thousandths of an inch or millimeters. general machine practice is to use a depth of cut up to five times the rate of feed, such as rough cutting stainless steel using a feed of 0.020 inches per revolution and a depth of cut of 0.100 inch. which would reduce the diameter by 0.200 inch.
A. general . the lathe is a machine tool used principally for shaping articles of metal, wood, or other material. all lathes, except the vertical turret type, have one thing in common for all usual machining operations the workpiece is held and rotated around a horizontal axis while being formed to size and shape by a cutting tool.
Dec 08, 2016nbsp018332in-feed grinding also called plunge grinding is used to grind cylindrical parts with notches or complex shapes, such as gear shafts. here, the workpiece rest blade needs to be tooled to match the shape of the part. the grinding and regulating wheels must be dressed to match the parts desired profile cut.
