ACP Fusion (DFM) key terms

The practice of shaping a design so it can be produced reliably, cheaply, and at the intended volume, by accounting for process limits before drawings are released.

Adjusting geometry and build orientation so a part suits layer-based production, including self-supporting angles, powder removal paths, and orientation-dependent strength.

A structured check of a design against known process capabilities, tooling constraints, and inspection feasibility, producing a list of issues before release to production.

A calculation combining individual part tolerances to predict the worst-case or statistical variation of an assembly dimension, revealing whether parts will fit and function.

A symbolic language on drawings that defines allowable form, orientation, location, and profile variation relative to datums, communicating functional intent more precisely than plus-minus limits.

A coordinate system established from specified reference features on a part, giving inspection and manufacturing a shared origin for measuring orientation and location tolerances.

Automated validation that compares model geometry against a rule set such as minimum wall thickness or hole spacing, flagging features likely to fail in production.

The thinnest section a given process can form without short shots, warpage, or weak structure; it drives material choice, cycle time, and part cost.

A slight taper applied to vertical faces so a part releases cleanly from a mold or tool, preventing scuffing and ejection damage.

The boundary where two halves of a tool meet, separating molded surfaces; its placement governs where flash may appear and where side actions are needed.

A feature that blocks straight-line removal of a part from its tool, requiring side actions, lifters, or a design change to release.

Simplifying a product so it has fewer parts, easier handling, and unambiguous insertion motions, reducing assembly time and error on the line.

A design or fixture feature that makes an incorrect assembly action physically impossible or immediately obvious, preventing defects rather than detecting them later.

The ordered list of joining and handling steps that builds a product, used to check access, tool clearance, and whether parts can actually be installed.

A structured list of every component, material, and quantity in a product, forming the backbone for costing, purchasing, and configuration control.

Software that converts model geometry into machine instructions, generating toolpaths, feeds, speeds, and post-processed code for production equipment.

The calculated route a cutting or deposition tool follows through space, including entry, cutting passes, retracts, and links between regions.

A translator that converts neutral toolpath output into the specific command dialect a particular machine controller expects, handling axes, codes, and machine quirks.

The molds, dies, fixtures, and gauges built specifically to produce a part, usually carrying long lead times and significant upfront cost.

The direction a part is positioned relative to the build platform or machine axis, affecting support needs, surface finish, strength, and build time.

Sacrificial material printed or machined to hold overhanging geometry during building, later removed and often leaving marks on the finished surface.

Producing a part close to final dimensions so only minimal finishing is needed, trading higher process cost for large savings in material and machining time.

A statistical measure of how well a stable process meets specification limits, comparing the spread and centering of output to the tolerance band.

Monitoring production with control charts and sampling so that drift and special-cause variation are detected before out-of-spec parts are shipped.

A full dimensional and documentation verification of the first production part, confirming that tooling and processes yield a conforming item before volume runs.

A numerical method that divides a model into small elements and solves governing equations to predict stress, deflection, vibration, or thermal response under loads.

Simulation of fluid flow, heat transfer, and pressure fields by solving conservation equations over a discretized domain, used to check cooling, flow, and drag.

The check that refining element size no longer changes results meaningfully, establishing that a simulation answer is independent of discretization choices.

A stated constraint or load applied at model edges, such as fixed supports or pressure, defining how the simulated system interacts with its surroundings.

A defined combination of forces, pressures, temperatures, and accelerations representing one service scenario that a design must withstand.

The ratio of allowable strength to expected applied stress, providing margin for uncertainty in loads, material properties, and analysis assumptions.

Statistically derived strength values that a design may use, accounting for scatter in test data and environmental knockdowns rather than relying on typical values.

A simulation-ready virtual counterpart of a physical product or process, kept synchronized with real data so behavior can be predicted and compared.

Comparing predicted results against physical test or field measurements to establish that a model represents reality closely enough for its intended decisions.

A system of record that manages product data, versions, structures, and processes from concept through service, keeping stakeholders on consistent information.

Disciplined tracking of changes to files and models so that any past state can be identified and restored, and concurrent edits do not silently overwrite each other.

A formal record requesting, justifying, approving, and tracking a modification to a released design, including affected documents, parts, and effective dates.

Running design, manufacturing, and support activities in parallel with shared data, so process constraints surface early instead of after design freeze.

The connected trace of data linking requirements, models, process plans, and as-built records, allowing any decision to be followed across disciplines and lifecycle stages.
