公式 / 邏輯
Uses table interpolation from public ASTM E140-style steel conversion tables. HRC↔HV↔HBW is limited to non-austenitic steels in roughly the HRC 20–68 range; HRB values are low-hardness steel guidance only. Conversions are approximate and material-specific.

工程提醒：這些工具適合估算與規劃。正式加工前，請依刀具型錄、機台能力、材料資料與適用標準重新確認。
常見問題
Can this result be used directly on a CNC machine?
Use it as a starting value only. Check the tool manufacturer data, machine limits, workholding, coolant and material condition before production.
Which units does the calculator support?
The calculator shows the units beside each input. Select metric or inch units where the page provides a unit-system control.
Why can shop results differ from the calculation?
Tool geometry, coating, runout, rigidity, chip evacuation, material hardness and machine power can change the practical result.
