1Workpiece & Tooling
2Cutting Parameters
3Component, Cost & Power
Model Notes
Extended Taylor: V·Tn=C. Reference speed scaled by substrate, coating, finish class, coolant and interrupted-cut derating, then corrected for feed/DOC deviation from baseline (exponents a≈0.3, b≈0.15). Ra estimate uses Ra≈f²/(8r). Power estimate uses Pc=MRR·kc/(60×10&sup6;×η), η=0.8, kc from material group.
Planning-level estimate from published ISO/handbook data — validate against trial cuts and insert manufacturer catalogs.
1Workpiece & Cutter
2Cutting Parameters
3Component, Cost & Power
Notes
N=(Vc×1000)/(πD). Vf=fz(eff)×z×N. Chip thinning: when ae<D/2, fz(eff)=fz/√(ae/D) is used for surface/finish, while the programmed fz×table-feed relation still governs Vf. Time=(length+√(ae(D−ae)))/Vf×passes.

Notes
Turning holder life is not a Taylor cutting-edge model — it is governed by clamp-mechanism fatigue (insert-change cycles), seat wear from cutting force, and coolant/corrosion calendar life. Governing life = the lower of the fatigue-cycle-derived years and the corrosion/seat-wear calendar cap. Boring bars add an overhang (L/D) derating for vibration-driven fatigue.

2Usage & Cost
Notes
Milling holder/cutter-body life is governed by insert-index clamp-cycle fatigue, centrifugal/imbalance stress at running RPM, and coolant-channel/taper corrosion. Governing life = the lower of the fatigue-cycle-derived years and the corrosion/seat-wear calendar cap. Shrink-fit and collet holders have no discrete clamp cycle in the same sense — their base rating instead reflects thermal-cycle/collet-clamp fatigue.
Holder Inventory Register 0
Track individual physical holders against their predicted life so you know which ones are approaching retirement before they fail on the machine.
| Asset ID | Category | Type | Install | Used / Predicted | % | Gauge / Offset | Last Runout | Status | Actions |

Printable Asset Labels
Select a registered holder and print a QR + text label for the physical tool (asset ID, type, gauge length).
Incident Log
| Date | Asset ID | Severity | Description | By |

Major/Crash incidents automatically flag the matching register entry for inspection.
Retirement Log & Learned Calibration 0
When a holder is retired from the register, its actual cycles-to-retirement feed a rolling calibration factor per holder type — applied automatically to the Turning Holder / Milling Holder life estimates above.

Job / Routing Sheet Holder Cost Rollup
Build up the total holder-related cost per component across every operation in a routing sheet (turning holder + milling holder + any boring/grooving holder), the same way the Batch Import tab rolls up insert costs.
| Operation | Holder Cost/Part (₹) |
|---|
Compare up to 3 Substrate + Coating Combinations
Uses the same workpiece material and cutting parameters (turning model) across all combinations so you can weigh life vs. cost vs. cycle time before committing to a premium grade.
Batch Tool-Life from Routing Sheet (CSV)
Upload a CSV of turning operations to get tool life, cost/part and totals for an entire routing sheet in one pass. Columns required (header row, exact names): Operation, MaterialId, SubstrateId, CoatingId, Vc, Feed, DOC, TimePerPart, InsertPrice, Edges. Use the IDs shown in the Reference tab tables, or download the template below.

ISO 1832 Insert Designation Decoder
Enter a standard ISO turning/milling insert code (e.g. CNMG 120408) to break down shape, clearance, tolerance, type and dimensions. This is a designation reference only — grade/substrate/coating is manufacturer-specific (the suffix after the dimension block, e.g. -PM 4325) and is not decoded here; select it manually in the calculators.
Saved Estimates 0
Enter the actual observed tool life from the shop floor next to a saved estimate and click "Apply Calibration" to build a self-correcting multiplier for that material + substrate + coating combination. Future calculations for the same combination automatically apply the learned correction.
Life & Cost Trend
Pick a material + substrate + coating combination that has multiple saved estimates over time to see whether predicted life or cost/part has been drifting.

Supabase Sync (optional)
Connect the same Supabase project used across your PPC/QA tool suite to sync saved estimates across devices/users. Leaving this blank keeps everything local to this device (localStorage).
Required Table Schema
Run once in the Supabase SQL editor before syncing:
create table if not exists tool_life_estimates ( id bigint primary key, type text, ts timestamptz, material text, substrate text, coating text, life numeric, parts numeric, cost_per_part numeric, vc numeric, actual_life numeric ); alter table tool_life_estimates enable row level security; create policy "allow all for authenticated/anon - internal tool" on tool_life_estimates for all using (true) with check (true);
