Stock removal is usually done with an oxyfuel torch in metal fabrication.
Material removal is a term commonly used to describe the action of removing some amount of material from a workpiece. There are several different ways to go about this process, including common approaches such as milling, drilling, grinding, filling and planing. The choice of how to proceed with stock removal will often depend on the type of material involved, along with the type of part being manufactured.
The idea of stock removal is common in many manufacturing applications, including anything involving metal or woodworking. The idea is to remove excess materials that will not be part of the final design of the object. For example, if the product is being created using metal components, grinding the components into the proper shape before starting the joining would be an example of material removal. Likewise, planing and sawing are common approaches to the removal process when it comes to woodworking projects such as furniture construction.
One of the purposes of stock removal is to assist in reshaping the raw materials to match the finished product design. An example of this type of activity can be found in the production of knives. Here, the objective is to mold the metal used for the blades into the proper thickness and shape, often using grinding and other machining techniques to get rid of excess material that is not needed. In this application, the metal can be heated to make the shaping process easier to perform and then follow with the lapping to get the sharp edges needed for the knife.
Assuming the blade handle will be made of wood, shaping the wood by planing or some sort of lapping process may also be involved in the overall finish of each knife. Here, stock removal is used to ensure that the handle is the right size for the knife blade and that the handle fits comfortably in the hand, minimizing the possibility of slipping and resulting in cuts on the hand while using the device.
De-stocking can be used for do-it-yourself projects at home, as well as part of a larger manufacturing process in a factory environment. The scope of construction or manufacture will also determine the exact methods that are used in the process. For simple home projects, removal tools are often common devices such as hand mills, drill bits, and grinding wheels. Larger operations will utilize stock removal equipment that can withstand repeated action, making it possible to produce a series of finished units during the course of a workday.
