高送りミーリングと従来ミーリングの比較。加工パラメータの即座のCost Savings per Part, Annual Savingsを取得。
悪い数値のコストは？典型的なジョブショップシナリオで計算してみましょう。もし 工具寿命経済性 が15%攻撃的すぎる場合、 Kyocera エンドミルを余分に買うだけでなく — 予期しないダウンタイム、手直し、納期遅れのコストを払っています。
| Premature Nachi tool failures | $6,400/yr |
| Unplanned machine downtime | $12,200/yr |
| Rework / scrap parts | $8,700/yr |
| Excess Schunk holder wear | $2,100/yr |
| Total Annual Loss | $29,400/yr |
シナリオを逆にしてみましょう。工具寿命経済性を最適化 — メーカー推奨の開始パラメータを特定のKyoceraまたはNachi工具に使用し、Hexagonプリセッターで検証 — することで年間約3万ドルを回収できます。これは新しいOkuma工具プローブまたは1年分のKyoceraインサートに相当します。
ROIは即時。最初のパーツが最適化され、最初の節約日。
Longer tool life directly reduces cost per part. This calculator quantifies the savings from switching to a longer-lasting tool — whether from a better carbide grade, improved coating, or optimised cutting parameters.
Doubling tool life on a high-volume line can save thousands annually. For example: a $50 tool lasting 100 parts vs 200 parts saves $0.25/part. At 100,000 parts/year, that's $25,000 in tooling cost alone — plus reduced downtime for tool changes.
Premium coatings (AlTiN, TiSiN), optimised speeds and feeds (start at 80% of maximum recommended SFM), improved coolant delivery (through-tool coolant at correct pressure), and reduced runout are the four biggest levers.
Not always. If a premium tool costs 3× more but lasts only 2× longer, the cheaper tool may have better economics. Use this calculator to compare total cost per part, not just tool life in minutes.
Enter the tool cost, old tool life (parts per edge), new tool life, and annual production volume. The calculator shows savings per part and projected annual savings from the tool life improvement.
