What is Tool and Die?
Tool & Die is a process where skilled manufacturing tool & die makerss create molds, fixtures, machine tools, cutting tools, gauges, and other tools for use in manufacturing processes. An example would be milling cutters or form tools. Tool and die making is a skilled craftsmanship, where the tool maker has learned through academic education and hands on instruction and apprenticeship.

How Does Tool and Die work?
Generally the Tool and Die maker will be working off of engineering drawings; marking out the designs on a raw material (usually metal or wood). The next step is to cut the piece into size and shape. This is done manually using machine tools such as jig grinders, grinding machines, milling machines, and lathes, among others. Hand tools will also be used at this point (for example: files). Additionally, many tool makers will now use computer-aided design software, CNC machine tools, and computer-aided manufacturing; helping the tool maker to be more accurate in the production of his projects.

The tool and die making process is generally used for the benefit of producing products. Some of the more common tools made include: Milling Cutters, Form Tools, Lathe Bits, and Metal Forming Rolls. Tool Making may further include making machine tools/precision fixturing to manufacture and/or test products during their creation. This is a common practice as it is often a necessary step in modifying standard tools and the fabrication of custom tools.

Tool makers usually work on manufacturing production floors or in tool rooms. Tool rooms are kept clean and cool so they reduce any metal expansion from higher temperatures. Manufacturing production floors and specialty machine shops are usually filled with machinery. To maintain safe working environments, machines have shields and guards.

What is Die Making?
A genre of tool making called Die making concentrates on the making and maintenance of dies. Machining dies requires a skill that demands a lot of precision to ensure that the punches and dies have accurate clearance.

What is a Die?
Tool makers are often die makers, hence the term 'tool and die' makers. A Die is a specialized tool used in industries where materials are cut or shaped by a press. Dies are custom made to the precise production specs of the final item produced. There are many types of dies, used for a wide variety of manufacturing processes and operations. The Die operation is typically named after the specific type of die that performs the process.

Press Die: used in fabrication of sheet metal parts. Usually consists of two parts: a punch and die
Bending Dies: can create straight line bends
Blanking Dies: used to produce a flat piece of material by cutting the material in one operation. Typically used to cut the outside contour of finished product. Known for accuracy, uniform appearance and flatness.
Broaching Dies: are often used to remove extra material from parts that are too thick for shaving.
Bulging Dies: A bulging die expands the closed end of the material.
Coining Dies: Used to form completely different surface features on the front and back of the same surface (an Embossing or Forming die would create mirror images on each surface).
Compound Dies: used to perform more than one process during one press cycle. A compound die is an inverted type of blanking die that punches upward, allowing the cutting of internal and external part features in one press stroke.
Curling Dies: used for a curling process, where the material is rolled into a curved shape.
Cut off Dies: used to remove excess material or to cut off material.
Extrusion Dies: use extremely high pressure from a punch to squeeze metal into a desired form.
Forming Dies: used to bend a blank along a curved surface.
Cold Forming Dies: this process uses the punch and the die to create the desired form.
Roll forming: a continuous bending operation where a strip of metal is passed through consecutive sets of rolls, using either pre-cut or post-cut dies.
Pancake Dies: used to perform blanking and/or piercing in a one simple procedure.
Progressive Dies: used to pass material through a set of operations for progressive modifications.
Trimming Dies: typically used in the last operation performed; used to cut away excess material or features from a part.

  1. Nicely explained the process, each step is very clear.I think anyone has no question about Dies and marking tools after reading this post.Thanks for your time and effort.
