Abstract
Contemporary market must provide products that adapt to customer needs,
which requires large investments and long-term employment. Producers have to
take care of the buyers’ different way of thinking. The quality of products and
services is an important economic indicator. The paper presents studies and
research in the field of bending of metal parts (thickness between 1 and 3 mm) on
CNC machines. This paper tries to provide answers to the many problems arising in
the companies due to the quality of the economic goods. In the technological flow of
the achievement of a metal product, bending is very important, the quality and
conformity of the product depending on this operation. The paper proposes
laborious research and studies on determining the drawings of metal parts with the
thickness between 1 and 3 mm, considering that other variables such: the
temperature variation during the processes of punching and bending, tool usage,
the tolerance between the surfaces of the bending tools, the vibrations of the
machines, their usage and the roughness of the sheet metals may influence the
quality and precision of the products. The calculation of the drawing (the geometry
in plane of the piece) becomes important because it must include the deformation
caused by the bending operation.
