The aim of this work is to clarify the interaction mechanisms between the drilling tool and material. Among the defects caused by drilling, delamination appears as to be of the most critical and may occurs at both the entrance and exit plane. This paper presents a prediction Hocheng-Dharan model of thrust force for drilling without delamination. HSS twist drills with different geometry were used fo (…)
Manufacturing simulation issues can be solved in a variety of different COTS (Commercial off The Shelf) simulation software – for example ARENA, QUEST, SIMUL8, Siemens PlantSimulation, etc. The input and output values can be stored in databases, but the interface has to be implemented by a developer. The output values (such as manufacturing time, average time of product waiting, etc.) from one simu (…)
The article describes an identification of material parameters from set of experiments. The experiments were made with hollow cylindrical specimens. The specimens were fabricated from the steel (11375). In this study are used the data obtained from 5 experiments (axis force, torque and their combination). Software ANSYS v.11.0 based on Finite Element Method (FEM) was used as a tool for the identifi (…)
The calculation of spindle dynamic compliance is usually performed taking into account only the mechanical system of the spindle and tool, while the influence of the machine tool frame is neglected. However, when performing machining operations characterized by high cutting forces – which typically arise e.g. during roughing – machine frame vibration may be induced. Under such conditions, a model o (…)
