Five-axis machining centers are normally classified into three structure types which are Tool-tilting-, Tool-Work-tilting- and Work-tilting-type. They are basically designed from conventional three-axis machining centers by addition with two rotational slideways. In this research it is described that the affect of structure errors on all kinds of five-axis machining centers which are working well for five-face machining is analyzed by form-shaping function. It is found that five-axis machining centers have nine variation of structure type. Normal Work-tilting-type of five-axis machining center is not exactly better structure than new proposed structure type in view of machining errors.
