This report examined tool wear in high-speed machining of tool steel with a hardness of HRC 63. Wear monitored periodically using the device for automatic geometric correction tool (length and radius) situated in the working area of the machine. The study was conducted on milling machine RAIS M400 with CNC Heidenhain iTNC 530i.

The concept of a hardware-in-the-loop experiment for high speed milling is introduced in this paper. The tool-workpiece interaction is virtually implemented in the experiment while the milling machine with the spindle is used as real element. In this paper, the basic components of the experiment are presented, namely, a contactless displacement sensor, a computational algorithm of the cutting force and a contactless electromagnetic actuator are discussed. Experiments on the prototype of the electromagnetic actuator are also shown to illustrate the potential of the concept. A feasibility study of the hardware-in-the-loop experiment is given, where the effect of the time delay included in the experiment is investigated.

For the purpose of investigating the surface defects on the machined surface in high speed milling of SiCp/Al Composites, the high speed milling experiments were performed on the precision milling machine (ops650).The machined surface was observed and measured by the OLS3000 Confocal Laser Scanning Microscope. The surface defects on the machined surface were classified and investigated. The surface defects mainly include grooves and holes due to the pulled-out particle. According to the geometrical characteristics of the pulled-out particles.

High speed milling (HSM) on inclined plane is the basic process of die and mould. The dynamic characteristics of the process are experimentally studied by changing the factors as inclined plane, cutting parameter and feeding mode on the high speed milling machine tool. The angles of inclined plane, spindle speed, feed amount and cutting depth are evaluated by the parameters of cutting forces and vibration. The feeding of projection process limits the milling vibrations mainly from horizontal (X) and (Y) directions. The cutting force reaches the peak value when the angle of inclined plane is 45°. The radial cutting depth shows more effects than the axial cutting depth to cutting force and vibration. However, the axial cutting depth should keep a minimum value when using ball mill.
