Method and strip steel knife from a steel strip having a bainite and decarburized surface. The steel strip has a generally rectangular cross-section, and the method includes machining a plurality of beveled surfaces in a region of a longitudinal edge of the steel strip to create at least a cutting surface defining a longitudinal cutting edge; first hardening at least a part of the cutting surface to form a first cutting edge region of the longitudinal cutting edge; smoothing the cutting surface of at least the first cutting edge region toward the longitudinal cutting edge; and at least one further hardening in the first cutting edge region to form a distal cutting edge region of the longitudinal cutting edge within the first cutting edge region having an increased material hardness with respect to the first cutting edge region located outside the distal cutting edge region.

Methods, devices, and apparatus for processing a strip of material including: measuring and feeding the strip of material to a predetermined length; and making broaching cuts on the strip of material using a plurality of cutting tools configured to make a plurality of angled cuts.

The invention relates to steel-rule cutting dies having a die block with at least one kerf configured to receive a corresponding steel-rule intended to be partially inserted into the kerf. The die block also has at least one element having magnetic properties, such as for instance a magnet, located or embedded in proximity to each kerf for providing a magnetic field that retains the steel-rule when the steel-rule is received into the corresponding kerf. The presence of the magnetic element(s) in proximity to the kerf(s) allows maintaining the corresponding rule(s) in position within its kerf even if the kerf is cut loosely. The corresponding rule may be quickly and easily inserted and accurately maintained even if the die block expand or retract under atmospheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifing and longer run-time.

A method for performing a design rule check of a computer aided design (CAD) file corresponding to a geometry of a tool for use in a process for making an article from a starting material. Design rules defined to avoid a geometry of the tool documented as causing an inefficiency in a non-printing or non-platemaking operation of the process are stored in a computer. A design rule checking (DRC) module of the computer processes the CAD file relative to the stored design rules, identifies violations, automatically suggests design changes responsive to each violation, receives a user input responsive to suggested design changes, and modifies the CAD file in response to the user input. Non-transitory computer readable media containing code for implementing the method and related CAD systems are also described.

An assembly and method of forming a press cutting die that includes a cutting blade that is supported by a blade support assembly or blade support. The blade support includes a first base portion and a second base portion that are each contoured to cooperate with one another to capture a portion of the cutting blade along an interface between the first and second base portions. Preferably, one or more keys extend between the first and second base portions and traverse the geometric plane associated with the cutting blade. Such a press cutting die is particularly applicable for cutting biologically compatible materials having a desired shape from a bulk source of the biologically compatible material.

The present invention provides a blade cutting device capable of simplifying the work of cutting blade-shaped materials (31), and accurately forming blades. The blade cutting device includes a material accommodation section (32) comprising a plurality of accommodation chambers (R1 to R10) for accommodating the band-shaped materials (31) used to form blades, in such a manner as to be sorted by type; a band-shaped material machining section (33) comprising a feed unit for feeding a band-shaped material (31) pulled out from a predetermined accommodation chamber and a cutting unit (55) for cutting the band-shaped material (31) into a predetermined length for forming blades; and a control section for causing the material accommodation section (32) to move so as to locate the predetermined accommodation chamber of the material accommodation section (32) at a position facing the band-shaped material machining section (33). The predetermined accommodation chamber is located at the position facing the band-shaped material machining section (33), and the band-shaped material (31) pulled out from the predetermined accommodation chamber is cut into a predetermined length for forming blades. The work of selecting the band-shaped materials (31) can be simplified, and blades can be formed accurately.

A mold used for blanking a metal plate to shape a blank to be drawn. The mold has a surface treatment film and a top face to be brought into contact with the metal plate and a peripheral end face communicated indirectly with the top face. At least the top face is coated with the surface treatment film.

Applying padding material around shaped cutting blades includes: receiving a blade shape diagram and a rule of blade; bending the rule of blade according to the blade shape diagram to produce the shaped cutting blades; and applying the padding material around the shaped cutting blades using the blade shape diagram to produce a padded shaped cutting blade, wherein the padding material provides a spring action to quickly detach the shaped cutting blades from a plate matter.
