CNC Milling Machine

The objective of this thesis is creating 3-axes CNC milling machine by using step motor in open-loop control and also directly operating via microcomputer. Designed work can be write by programming and simulating for convenience and suitability to beginner. From the result of work, we acquired 3-axis CNC milling machine that is not expensive, low operating cost, and perform machining job efficiently.

This thesis is studied Resonant Converter,shows that almost powerlosses happen in converters because of non-ideal characteristics of switches. Resonant Converters were devoloped to solve this problem by resonant tank circuit theorem ,compose of inductor and capacitor,make the turn on switching occur under Zero-Voltage condition or the turn off switching occur under Zero-Current condition thus coverters can work at high frequency and have high efficiency.
