What is planning?

Flattening is a technique used to shape sheet metal.

Flattening is a technique used to bend and shape thin sheet metal parts. The process involves tapping the metal with a specialized planing hammer as it rests on a rounded stake to smooth out defects and achieve the proper curve. Planing is commonly performed in auto repair shops, aircraft factories, and many other industrial metal fabrication environments. In the past, workers flattened sheets by hand, but most experts today use pneumatic or electric machines to shape metal parts quickly and accurately.

Planing was used in medieval times to make armor for knights.

Metalworking has been a common practice throughout the world for many centuries, and blacksmiths used planing tools to create sword hilts, metal bowls, and body armor. Today, professionals plan sheet metal to manufacture car fenders, gas tanks, airplane bodies and decorative parts such as lamps. Many hobbyists and hobbyists also use the technique in their own shops, while restoring vehicles or creating decorative jewelry.

After shaping a sheet into its final basic shape using rougher machining techniques, a specialist places the material on a stake or anvil and hammers out small imperfections. The planing pile is basically a small metal sphere on top of a rod that is attached to the ground. Several different hammers can be used, depending on the type of metal and the level of perfection the worker hopes to achieve. Some experts use large wooden mallets and ball hammers in their work, while others employ planing hammers that are specially designed for the task.

Small dents or raised edges on a piece of metal are tapped with the planing hammer and smoothed along the curve of the stake. It typically takes hundreds of strokes to work a sheet perfectly. By carefully lining up the part on the pile, a metallurgist can achieve almost any desired shape. A professional can manipulate a sheet to create a long, steady curve or nearly round it into a perfect circle if desired.

The metal is machined in most modern auto repair shops and factories. A pneumatic or motor-controlled planer can make a more accurate finished product in a fraction of the time and effort required with hand tools. A worker lines up the metal part and controls the hammer with a foot pedal or hand trigger. Using air pressure or electrical power, the hammer taps the sheet lightly several times per second. The worker must simply push and pull the metal piece by hand during work to work the entire sheet.
