Deep bored hole DFM check

Deep bored hole issue in CNC machining turning design refers to the challenge of creating deep and narrow holes in a workpiece using a turning process.

The issue arises due to the length-to-diameter ratio of the boring tool, which affects the stability and precision of the process. As the depth of the hole increases, the tool's deflection increases, reducing accuracy and causing tool failure.

Deep bored hole detection conditions

MTK identifies this issue when the following condition is met:

where:

• $D_h$ — actual bored hole depth
• $Di{a}_h$ — actual bored hole diameter
• $Rt$ — expected maximum bored hole depth to diameter ratio

How MTK detects deep bored holes

MTK automatically analyzes B-Rep CAD models for deep bored holes. The SDK checks the relevant geometry against DFM criteria to identify potential issues that can increase manufacturing complexity or cost, or lead to quality or assembly problems.
