The term 'chopping down' can be broken down into two separate words, 'HEWING' and 'axing'. 'HEWING' is the process of cutting or shaping a piece of wood with an ax or other tool. It is usually done to make a straight line or to create a specific shape. 'Axing' is the process of using an ax to cut down a tree or other large object. Both processes are used in forestry and construction, and are essential for the production of lumber and other materials.
