Abstract :

CNC Drill Bits Play A Crucial Role In Modern Manufacturing By Producing Accurate And High-quality Holes In A Wide Range Of Engineering Materials. The Performance And Durability Of A Drill Bit Are Strongly Influenced By Its Geometric Design And The Material From Which It Is Manufactured. This Study Presents The Design And Static Structural Analysis Of A CNC Twist Drill Bit Using Different Tool Materials, Namely High-Speed Steel (HSS), Cobalt High-Speed Steel (HSS-Co), Tungsten Carbide, And Polycrystalline Diamond (PCD). A Three-dimensional Model Of The Drill Bit Was Developed Using SolidWorks Software And Imported Into ANSYS 2025 R2 For Finite Element Analysis. Static Structural Analysis Was Performed Under Identical Operating Conditions, Where The Drill Bit Was Subjected To An Axial Thrust Force Of 564 N And A Torque Of 1.69 Nm. Key Performance Parameters, Including Total Deformation, Equivalent Stress, And Equivalent Strain, Were Evaluated And Compared. The Results Provide Insights Into The Mechanical Behavior Of Different Drill Bit Materials And Help Identify The Most Suitable Material For Improved Machining Performance, Tool Life, And Productivity.
