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.

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.

1Holder & Application

Better-repeatability interfaces fret less at the taper/clamp face, extending the corrosion/seat-wear calendar cap.

Clamp screws/wedges wear far faster than the holder body and are tracked as a separate consumable in the cost roll-up.

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.

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.

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.

OperationHolder Cost/Part (₹)
Total Holder Cost / Component

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.
