    The paper presents case of tool damage during valve seat machining process. The tool for valve seats machining was described, details of tool damage were characterized. Damage was illustrated by wrongly machined (destroyed) valve seat, cutting forces for correct valve seat machining and cutting forces for tool destruction case. For analysis was used LVDT contact sensor. General conclusions arising from tool damage process observation were presente

    The paper presents cutting forces simulation method for valve seats machining. Cutting forces affecting on tool used for valve seats machining and mathematical relations used for simulating forces were described. Tool used for valve seats machining was presented and machining process was described. Analysis of tool setting against machined valve seat impact on area of the chip on tool blades was made by simulation. Simulated cutting forces for different tool settings against machined valve seat were presented. Test stand for verifying simulated cutting forces against measured cutting forces was characterized. General conclusions arising from simulations and further research plans were presente

    The paper describes micromilling machine and implemented sensor system for microcutting operations. Sensor system can be used for cutting forces, accelerations, acoustic pressure and tool displacements measurement. Cutting forces and accelerations signals were used for cutting depth, hardness of workpiece and excitation frequency of rotating tool monitoring. Other signals obtained during experiment will be used in further work. Conclusions arising from performed experiment and further research plans are presente
