PI-Estimator
Turn manufacturing geometry into quoting intelligence.
PI-Estimator analyzes CAD geometry, manufacturing features, dimensional controls and process requirements to help manufacturers build faster, more consistent and more defensible machining estimates.
Talk to TSRB SystemsThe problem is not opening the CAD file.
The problem is understanding what that geometry means to manufacturing before you commit to a price.
Estimating depends on experience
Experienced estimators recognize difficult geometry, tight tolerances, unusual tool access and inspection requirements almost instinctively. That knowledge can be difficult to reproduce consistently across an organization.
Complexity is easy to underestimate
A part that appears straightforward may contain compound holes, multiple machining orientations, controlled datums, 3D surfaces and tolerance requirements that dramatically affect manufacturing cost.
Slow quotes lose opportunities
The longer engineering spends interpreting an RFQ, the longer the customer waits. But rushing the estimate can expose the manufacturer to margin loss.
PI-Estimator helps answer the questions behind the quote.
Instead of treating a STEP model as a picture, PI-Estimator is designed to interpret manufacturing characteristics that influence routing, machining time, inspection effort and ultimately selling price.
Analyze solids, faces, edges, dimensions, volume, surface area and geometric characteristics.
Recognize holes, pockets, slots, channels, steps, bosses and complex compound features.
Identify tight tolerances, restricted access, multiple orientations, complex 3D surfaces and enhanced inspection requirements.
Generate a preliminary process route, estimated setup requirements, machining operations and inspection allowances.
From STEP model to manufacturing intelligence
PI-Estimator concepts were applied to the NIST FTC-06 AP242 STEP manufacturing test model together with its fully toleranced manufacturing drawing.
| Analysis Item | Detected Result |
|---|---|
| Valid solids | 1 |
| Faces | 187 |
| Edges | 573 |
| Vertices | 527 |
| Overall envelope | 12.000 × 9.850 × 3.850 in |
| Finished volume | ≈202.82 in³ |
| Surface area | ≈439.28 in² |
| Planar faces | 71 |
| Cylindrical faces | 88 |
| Conical faces | 8 |
| Spherical faces | 8 |
| Toroidal / fillet faces | 12 |
Feature recognition matters because surfaces are not operations.
A manufacturing estimator cannot simply count cylindrical CAD faces and call each one a hole. Compound geometry must be interpreted as manufacturing features.
PI-Estimator is intended to distinguish manufacturing concepts such as open pockets, closed pockets, slots, steps, channels and compound holes rather than reducing them to generic CAD surface counts.
Geometry tells you what to cut. Tolerances tell you how difficult it will be.
The NIST example contains substantial PMI and dimensional control, allowing PI-Estimator to identify features that may require precision machining and enhanced inspection.
Examples include Ø0.562 ±0.008, Ø0.415 ±0.008, Ø0.281 ±0.008 and Ø0.250 ±0.008.
Positional tolerances approach Ø0.015 in on selected features.
Multiple datum systems are included throughout the manufacturing definition.
Surface geometric controls are present even though an explicit Ra roughness value is not specified.
Just as important: PI-Estimator should know what not to assume.
No material specified?
The estimator should request it rather than silently selecting a material.
No thread specification?
A cylindrical feature should not automatically be interpreted as threaded.
No Ra surface finish?
A profile tolerance should not be converted into an invented roughness requirement.
Complex geometry but no conventional undercut?
The system can distinguish restricted tool access from an actual undercut requirement.
From feature recognition to a preliminary manufacturing route
Once the geometry and manufacturing controls are understood, PI-Estimator can begin constructing an initial process plan.
3-axis machining is possible but would require multiple setups.
3+2 machining is appropriate.
5-axis machining is preferred where reducing setup count and access risk provides economic benefit.
Build the estimate — and expose the assumptions.
Geometry analysis produces facts. Machining-time estimation introduces assumptions. PI-Estimator is designed to keep those two things separate.
| Operation | Estimated Time |
|---|---|
| Saw / material preparation | 10–15 min |
| Setup and indicating | 90–120 min |
| CNC rough milling | 150–210 min |
| CNC finish milling | 90–130 min |
| 3D contour machining | 60–90 min |
| Drilling / boring | 35–50 min |
| Manual deburring | 30–45 min |
| Inspection / CMM | 75–120 min |
| Handling / tool-change allowance | 30–45 min |
Estimated range: approximately 9–13 hours prior to CAM simulation and final manufacturing engineering review.
Material utilization becomes quoting intelligence.
Starting from the detected model envelope, PI-Estimator can establish a preliminary raw-material requirement and calculate the amount of stock likely to become chips.
Material selection remains a required quoting input when it is absent from the supplied product definition. That matters: an aluminum and steel version of the same geometry can produce radically different material, machining and handling costs.
From manufacturing intelligence to an RFQ starting point
Using a one-off 6061-T6 aluminum assumption, PI-Estimator can combine process assumptions with shop-specific cost rates.
| Cost Center | Hours | Rate | Cost |
|---|---|---|---|
| CAM / programming | 3.0 | $110 | $330 |
| Setup | 1.75 | $110 | $193 |
| CNC machining | 7.0 | $125 | $875 |
| Deburr | 0.6 | $60 | $36 |
| CMM inspection | 1.5 | $100 | $150 |
Processing: $1,584
Material: $270
Tooling / consumables: $100
Direct estimated cost: $1,954
Example manufacturing overhead: $352
Estimated cost basis: $2,306
Illustrative selling price at 30% gross margin: ≈ $3,294
A quote your estimator can review instead of build from scratch
Quantity: 1
Material assumption: 6061-T6 aluminum
Estimated manufacturing time: ≈11 hours
Estimated lead time: 7–10 business days after approval and material availability
Material is not specified in the supplied product definition. Estimate is provisional based on 6061-T6 aluminum.
Automate the analysis. Keep manufacturing judgment in control.
PI-Estimator is not intended to replace the estimator, manufacturing engineer or CAM programmer. It is intended to give them a much stronger starting point.
The system can expose detected facts, identify assumptions, highlight uncertainty and provide a preliminary route and cost model for expert review.
Why PI-Estimator?
Quote faster
Give estimators a structured starting point instead of beginning every RFQ with manual geometry interpretation.
Quote more consistently
Apply common feature, complexity, tolerance and costing logic across estimators and facilities.
Protect margin
Make difficult geometry, inspection requirements, setup complexity and uncertainty visible before a selling price is committed.
Capture manufacturing knowledge
Turn estimating experience into reusable rules instead of leaving critical knowledge only in the heads of experienced personnel.
Improve RFQ discipline
Clearly separate supplied requirements, detected facts and estimator assumptions.
Learn from actual production
Compare estimated routing, time and cost against actual manufacturing results to continuously improve future estimates.
Estimating becomes more powerful when it learns from production.
PI-Estimator fits naturally within the TSRB Systems Production Intelligence approach.
A conventional quoting system estimates what should happen. Production Intelligence can provide evidence about what actually happened.
Machine time, setup duration, downtime, production rate and actual job performance can ultimately provide the feedback needed to improve estimating models instead of allowing quoting assumptions to remain static for years.
What if your next RFQ arrived already analyzed?
PI-Estimator is being developed to turn manufacturing product definition into actionable estimating intelligence — helping manufacturers respond faster while protecting the engineering judgment behind every quote.
