公式 / 逻辑
Hole range = basic size + EI/EH. Shaft range = basic size + ei/es. Clearance = hole − shaft.
Hole range = basic size + EI/EH. Shaft range = basic size + ei/es. Clearance = hole − shaft.
工程提示：这些工具用于估算和方案规划。生产参数需结合刀具样本、机床限制、材料数据和适用标准复核。
常见问题
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.
