Original abstract

A study of the cutting force components (in axial and tangential direction)and wear process when drilling a glass fibre reinforced plastic and carbon prepreg was made. Four component piezoelectric dynamometer KISTLER 9272, fully controlled by a PC, and statistical assessment were used to measurement of the torque and forces. Multiple regression analysis was used to determine the complex relationships between cutting torque and forces versus the drill diameter, feed per revolution and machined material. The recommended drilling material is sintered carbide (ISO grade K10-20) with the TiAlN coating because of the low cutting forces and the low wear rate. HSS and coated HSS suffers from the intensive flank wear, followed by high increments in the axial force and delamination of not-supported distal layers of the drilled material dur-ing drilling.

Studie řezných sil při vrtání kompozitních materiálů vyztužebných skelnými a uhlíkovými vlákny. Statistické zpracování regresních vztahů. Doporučený řezný materiál – SK K10-20. HSS nedoporučen v důsledku rychlého otěru.
