Detailed Description

Describes deep hole issues found during cnc machining drilling design analysis.

Drilling deep holes is a complex task that requires careful consideration of various factors such as drill geometry, coolant supply, chip removal, and machine rigidity. During the drilling process, chips and heat generated from the cutting action accumulate in the hole and can cause tool wear and breakage, as well as damage to the workpiece. Another challenge is maintaining the straightness and accuracy of the hole. As the drill penetrates deeper into the workpiece, it may deflect due to the increased cutting forces.

Contains hole that fails the following condition:

\[ \large D_h \leq Dia_h * Rt \]

\[ \begin{aligned} & \small D_h - \text{actual hole depth} \\ & \small Dia_h - \text{actual hole diameter} \\ & \small Rt - \text{expected maximum hole depth to diameter ratio} \end{aligned} \]

See also: DFMMachining_Analyzer, DFMMachining_DrillingAnalyzerParameters.MaxHoleDepthToDiameterRatio()

Examples: MTKConverter/Program.cs, MTKConverter/main.cxx, machining/dfm_analyzer/Program.cs, and machining/dfm_analyzer/main.cxx.
