Choose by feature geometry

Start with access, material conductivity and the feature that makes conventional cutting difficult.

Cut detailed profiles without tool contact

Wire EDM can support electrically conductive parts when a through-profile is difficult to reach with a conventional cutter.

Define in the drawingClosed or open profile, stock thickness, datum references, entry strategy and critical dimensions.

Review focusWire access, start position, corner intent, material state and profile inspection.

Useful RFQ question: Is the required geometry a complete through-feature?

Review access before widening the feature

Narrow conductive-material features may suit wire cutting when milling access or cutter stiffness becomes limiting.

Define in the drawingSlot width, depth or through-condition, end geometry, material thickness and tolerance notes.

Review focusAvailable wire path, internal radius, flushing, workholding and feature relationship.

Useful RFQ question: Can the wire enter and leave the complete cut path?

Translate sharp-corner intent into a feasible radius

Wire EDM can reduce internal corner radius, but the final value still depends on wire size, strategy and surface expectation.

Define in the drawingFunctional corner, maximum permitted radius, mating feature and inspection requirement.

Review focusWire diameter, skim strategy, profile continuity and whether the corner truly controls function.

Useful RFQ question: What is the largest internal radius the design can accept?

Cut after heat treatment by project review

Electrical discharge removes conductive material without relying on conventional cutting hardness limits.

Define in the drawingMaterial grade, heat-treatment state, hardness record, thickness and protected surfaces.

Review focusConductivity, material condition, recast-layer sensitivity, sequence and dimensional inspection.

Useful RFQ question: Is the part already at its final heat-treatment condition?

Reduce mechanical cutting force

A non-contact cutting route may help when thin geometry could distort under conventional tool pressure.

Define in the drawingWall or web dimensions, support surfaces, profile relationship and acceptable edge condition.

Review focusWorkholding, thermal behavior, cut sequence, part release and post-cut inspection.

Useful RFQ question: Which feature is most sensitive to cutting force or release stress?

Wire EDMVerified route

Machine accuracy is not the same as guaranteed part tolerance. Material, thickness, wire path, corner radius, surface expectation and inspection method determine the final route.

When wire EDM earns its place

The process is most useful when feature access, conductive material or cutting force changes the manufacturing decision.

E-01

Detailed through-profiles

Profiles and cutouts that require a continuous wire path through conductive stock.

E-02

Tooling and precision inserts

Drawing-defined inserts or plates where internal feature relationships matter.

E-03

Delicate conductive features

Thin sections or fine geometry that benefit from a low-force material-removal route.

From CAD profile to inspected feature

Wire EDM planning is a sequence of access, material, path, surface and verification decisions.

Review geometry

Confirm a through-path, corner intent, thickness and critical datum relationships.

Confirm material state

Check conductivity, grade, heat treatment and surfaces that must be protected.

Plan the cut

Define start strategy, wire path, workholding, pass strategy and release sequence.

Inspect the profile

Verify agreed dimensions, edge condition and relation to previously machined features.

Inspection follows the feature

EDM quality planning focuses on the profile and how it relates to the rest of the machined component.

Profile and positionCritical dimensions are tied back to the drawing's functional datum scheme.

Corner and edge conditionInternal radius intent and edge expectations are discussed before cutting.

Surface and material sensitivitySurface expectation and any recast-layer concern are reviewed by application.

Prepare a wire EDM RFQ

Give the engineer enough information to confirm access, material fit and feature intent.
