Abstract:
There are several proposed predictive cutting force model in machining industry. Engineers are keeping developing a new model to predict cutting forces. The cutting forces are the response that influenced by several factors during machining. A more precise, low cost and sustainable cutting performance are results of a good model.
This project is about a predictive cutting force model for end milling assessment. It is an investigation on the model whether it is valid or not. The methods of investigation are simulations and experiments. Throughout the project, the investigator demonstrated a comprehensive way to evaluate the model. It was achieved through the combination experimentally determined cutting forces with the C++ codes simulation program and statistics analysis (multiple regression method). The model was tested using two flutes end milling cutting tools with several factors. In this project, the factors that response the forces were spindle speed, feed rate and axial depth of cut. At the end of the project paper, the investigator proved that the particular model is good to predict the end milling cutting forces.
Final Year Project Description:
The main purpose for this project was to identify cutting forces of end milling from experimental data. It was an investigation on validation of the theoretical 3D model of cutting force in end milling with analysis on the experiment data. This analysis process involved the use of simulation program developed using Microsoft Visual Basic and large matrix analysis using MATlab software. At the end of the analysis, Minitab statistics analysis software was used to do the multiple linear regressions which are to predict the forces. There are several reasons why information from material removal is important which were obtained from this research:
1. To improve the cutting techniques.
2. To produce products of greater precision at greater useful life.
3. To obtain the ability to increase the rate of production and cutting performance.
3D dimensional cutting force formulation. It was a case study of particularly flat end milling cutting tools.
