Comparing EDM with Conventional Machining / /

Manufacturing engineers turn to EDM (electrical discharge machining) when milling, turning and grinding aren’t up to the task. It’s as if it’s a binary choice: if machining isn’t possible then chose EDM.

The reality is more complex. There’s a significant middle ground where EDM and conventional machining processes go head-to-head. Yes, the wire EDM cutting rate is lower than that milling or turning, but the process scores in other ways. Finished part geometry, workpiece hardness, surface finish and cost are all areas where conventional and EDM compete. Here’s a look at the advantages and limitations of EDM.

Advantages of EDM – Part Geometry / /

With EDM there are no cutting forces and neither tool nor workpiece rotate. In addition, wire EDM is done with wire typically 0.010” diameter. This all means:

  • Thin walls are possible.
  • Cut internal corners with very small radii.
  • Cut thin slots in extrusion dies with wire EDM.
  • Produce blind and high aspect ratio pockets with sinking EDM.
  • Produce non-round openings and cavities.
  • An alternative to broaching for 2D shapes like gears.

Advantages of EDM – Hard Materials / /

Material hardness has little effect on EDM wire cutting rate and doesn’t limit possible part geometries. Tungsten carbide, tool steel, Inconel and any metal harder than RC38 are all good candidates where conventional machining is slow and expensive.

A particular benefit is the ability to bring parts to their final size after heat-treatment. This takes out distortion brought about by hardening and stress-relieving.

Advantages of EDM – Surface Finish / /

Unlike conventional processes, an EDM surface has a very random texture. This is advantageous when directionality or “lay” could influence product performance. Additionally, EDM can create surface finishes as smooth as 5 RMS or around 4 micro-inches Ra. (This entails taking multiple skimming passes, for which the wire EDM cutting rate needs to be very low.)

Cost Advantages of EDM / /

On the right job – complex 2D geometry, hard material – EDM offers cost savings over conventional processes. For example:

  • No special tooling (saves money and lead time.)
  • Skimming passes eliminate secondary finishing operations.
  • Laminate layers of material to cut multiple parts simultaneously.
  • Enables reuse of cut out slugs rather than producing chips.
  • Avoids moving a part through multiple conventional processes. The final shape is achieved in a single set up (which also improves accuracy.)

Limitations of EDM / /

EDM requires an electrically conductive workpiece. It will not work on wood, plastics or composites.

Material removal rates (MMR) are usually lower than for conventional processes. However, direct comparisons are difficult to make since material hardness is such a big factor. MMR is usually calculated in cubic inches per hour with 0.4 in3/hr a typical rate. Calculated this way, a narrow kerf makes the wire EDM cutting rate quite high. Also, workpiece thermal conductivity and melting point have significant impacts on EDM MMR.

Wire EDM can only cut 2D profiles, although a fourth axis to incline the wire enables conical forms and tapers.

An Alternative to Consider / /

EDM is more than just a fall-back for when conventional machining isn’t up to the task. It’s a process to consider whenever the workpiece is hard, electrically conductive, and has specific geometric challenges or surface finish requirements.

Wire EDM Finishing Processes / /

Wire EDM is used to produce a smooth, mirror-like finish, but some finishing may still be required to customize a part. Common finishing processes that can be used for wire EDM parts include:

Painting

Painting a part adds color, varnish, or ink. The painting process may include powder coating, liquid coating, or e-coating. Powder coating uses an electrostatically charged powder which produces a scratch-resistant and uniform coat on the metal part. When a part is liquid coated, wet paint is applied. The e-coating process involves dipping the part into a bath of paint where both the part and paint are electrified, causing the paint to adhere to the part.

Transfers

Transfers apply a label or design to a part. During the transfer process, a design is placed onto the part and pressure is applied through a heated press. Transferring can also be used to print a design that may later be engraved onto the part.

Assembly

Assembly is needed if a part is produced in smaller units that must be pieced together to form a larger product. During assembly, the workpiece is bonded together with other parts to form the final product. Bonding procedures or fasteners may be used to fuse parts permanently or temporarily.

Drilling

Drilling adds a round hole to a part. Drill presses, tapping, or a milling machine may be used to drill. Different types of drills may be used including peck drills or spotting, depending on the type of mark required.

Deburring

Deburring removes raised edges or burrs from a part. Electrochemical deburring, thermal deburring or abrasive flow deburring may be used to deburr a part. Electrochemical deburring uses an anodic metal dissolution to remove unwanted material. Thermal deburring uses a combustible gas in a pressurized chamber to deburr a part. Abrasive deburring uses an abrasive slurry to deburr the part.
