Why precision machine shops choose Fast Quality Software

The dimensional-control problems every
precision machine shop knows

Readings recorded, but never against a limit

Inspectors write measurements on a report with no nominal, USL or LSL beside them. Nobody can tell at a glance whether a reading is in tolerance, and out-of-spec parts slip through to dispatch.

No SPC — you find out after the reject

Capability is calculated once a year, if at all. A characteristic drifts toward its limit for a whole shift and the first anyone knows is a bin of rejects, not a control chart nearing a control limit.

Gauges of unknown status on micron checks

A micrometer measuring to a thousandth is past its calibration date and has no Gauge R&R. Every reading it produced is suspect — a finding that can invalidate a whole lot's inspection record.

Rejection counted, never traced to a machine

Scrap is one monthly number. Which defect, which operation, which spindle caused it is never analysed, so the same machine keeps making the same oversize bore month after month.

How Fast Quality Software fixes each one
Every reading checked against nominal, USL and LSLThe specification master holds the limits per characteristic; inspection records the actual reading against them and dispositions the lot AC, RJ or AD — in tolerance is a fact, not a judgement call.
SPC on the characteristics that matterCp/Cpk and control charts are produced from the same spec limits for special characteristics, so a drift toward a limit shows on a chart before it becomes a reject.
Gauge R&R-qualified, in-cal instrumentsEvery gauge is registered, GR&R-qualified before use and driven through the calibration cycle by follow-up alerts — the register is your clause 7.1.5 evidence.
Rejection Pareto by defect and work centreDefect codes and defect-versus-work-centre mapping produce a Pareto that points at the machine, and a recurring reject escalates into an 8D that fixes the cause.
Dimensional-control lifecycle

From specification limits to a rejection Pareto —
one connected inspection record per part

Fast Quality runs the specification master, control plan, inspection, SPC and rejection on one platform — so what a part must measure, what it actually measured, and what was rejected are one connected flow, not a report and a whiteboard.

Define the limits → assign a calibrated gauge →

Fast Quality carries a precision part through its full inspection life — so what must be held is defined, what was measured is trusted, and a capability loss is caught on a chart, not in a reject bin.

Set nominal, USL/LSL and criteria per characteristic in the specification master, and flag special characteristics
Assign a calibrated gauge

01 — Specification master

What good means, to the micron, per characteristic

The specification master defines nominal, upper and lower specification limits (USL/LSL) and criteria per item and per operation — the single source both inspection and SPC read. Tight-tolerance control plans are built on it: each characteristic gets its limits, its gauge and its frequency, and special characteristics from the FMEA are flagged for closer control. See FMEA & control plan and inspection & SPC.

02 — First-article & in-process inspection

Checked at setup, during the run and before it ships

First-article inspection verifies the first pieces off a new setup against the full specification before the run is released; in-process inspection samples at the control-plan frequency; final and pre-dispatch inspection close the run. Every reading is captured against the spec limits and each lot dispositioned Accepted (AC), Rejected (RJ) or Accepted-Under-Deviation (AD) — the inspector's work list on one dashboard. See inspection & SPC.

03 — SPC: Cp / Cpk & control charts

See a drift on a chart, not in a reject bin

SPC is driven off the same specification limits the control plan uses. Variable readings captured at inspection are evaluated against nominal, USL and LSL, and capability indices (Cp, Cpk) and control charts are produced for the special characteristics. Initial process studies are a PPAP element; ongoing SPC shows whether a tight-tolerance feature is holding centre or drifting toward a limit — so you react before it scraps. See inspection & SPC.

04 — Calibrated gauges & Gauge R&R

Micron readings from a qualified, in-cal gauge

The gauge master registers every micrometer, vernier, plug gauge, height gauge and CMM with its least count/range, location, last-calibration date and frequency, deriving the next-due date. Gauge R&R quantifies repeatability and reproducibility, and a gauge must pass before it is used on a control-plan characteristic. Calibration follow-up drives the due → sent → calibrated → returned cycle and alerts on gauges approaching due. See gauge, MSA & calibration.

05 — Rejection Pareto & 8D

Which defect, which machine — then a corrective action

Every rejection carries a defect code and is booked as a material rejection (incoming) or line rejection (in process) against the item and work centre. The process rejection MIS produces a Pareto by defect, process and part, and defect-versus-work-centre mapping points at the machine making the scrap. A recurring or major rejection escalates into an 8D (D1–D8) whose CAPA amends the control plan. Dhruv AI clusters repeat defect remarks for you. See NCR & 8D/CAPA and Dhruv AI.

FAQ

Machining & precision quality software —
what buyers ask us

How does it control tight-tolerance dimensions?

Each characteristic has a nominal, USL/LSL and criteria in the specification master; the control plan links it to a calibrated gauge and frequency, and inspection records the actual reading against those limits.

Does it support first-article and in-process inspection?

Yes — first-article (setup) approval before a run, in-process sampling at frequency, and final/pre-dispatch inspection, all reading the same spec limits and dispositioning AC/RJ/AD.

How is SPC (Cp/Cpk) calculated?

Variable readings are evaluated against nominal, USL and LSL to produce Cp/Cpk and control charts for special characteristics; initial process studies are captured as a PPAP element.

How does it keep measuring gauges trustworthy?

A gauge master derives next-due dates, Gauge R&R qualifies each instrument, and calibration follow-up drives the due → sent → calibrated → returned cycle, with the register as clause 7.1.5 evidence.

Can we see which defect and machine cause most rejection?

Yes — rejections carry defect codes and a process rejection MIS produces a Pareto by defect, process and part, with defect-versus-work-centre mapping pointing at the machine.

Is it for precision machining, and cloud or on-premise?

It is built for shops inspecting to microns but serves IATF 16949 and ISO 9001 manufacturers of every kind, cloud and on-premise, across India and worldwide.
