DESC:TECHNICAL FIELD
[0001] The present disclosure relates generally to the field of punching or engraving machines. More particularly, the present disclosure relates to an apparatus for engraving markings on curved surface of workpiece, and method thereof.

BACKGROUND
[0002] The following description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0001] Generally, various punching machines are known and available which are suitable for marking through engraving. These punching machines perform the engraving by means of piercers and cylinders on the so-called ogive portion (i.e., a roundly tapered end of a two-dimensional or three-dimensional object, here - cylinder), the shape of which is given by the rotation of a profile with a circumferential arc configuration, around the axis of the cylinder.
[0002] As known in the conventional art, a piercing or a punching machine is used for marking writings, numbers and the like on metallic curved surfaces, such as the ogive-shaped portion of cylinders. This allows for the marking by engraving of symbols. The piercers are then disposed and held on a disc along a spiral arrangement. The disc is generally operated and driven into rotation by two independent mechanisms, one for the engraving of the symbols which are always the same, and the other for the variable symbols. The first mechanism causes an intermittent mono-directional rotational motion, while the second mechanism causes a continuous rotational motion, in both the senses. The disc bearing the piercers may be then brought into rotation alternatively by only one of said two mechanisms.
[0003] However, such punching machines lack 3-axes motion for stamping rows on an ogive or a curved portion, preferably of a cylinder. Further, these conventional machines also lack an arrangement for a plurality of stamping rollers corresponding to the 3-axes stamping rows. The traditional machines are generally manually operated and thus increase human error. Also these conventional machines are unable to mark the three lines consisting of letters and numbers simultaneously on the curved face.
[0004] There is therefore a need for a new, simple and compact stamping apparatus for engraving markings on a curved surface with 3-axes motion.
[0005] All publications herein are incorporated by reference to the same extent as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
