“…Factors influencing the profile accuracy. From the previous literature, we know that installation height error of the dresser, the swing transmission error of the dresser, and the wear of the dresser will create profile errors much less than the errors themselves [3]. In other word, these errors do not make a significant contribution to the wheel profile error.…”

The profile accuracy of the workpiece is mainly determined by the accuracy of abrasive wheel in the form-grinding process. Thus, the shaped wheel dressing becomes one of the key points in the form-grinding process. In order to grind the revolving curved surfaces grooves whose cross-sectional profiles are steep and smooth, a new NC dresser with three NC axes is developed by adding a swing axis on the basis of NC external cylindrical grinding machine. A wheel of any desired convex profile can be dressed when using the Diaform single-diamond dresser and the possible geometrical interference between the single-diamond dresser and wheel can be eliminated. By analyzing the influence of installation accuracy on the profile accuracy, a method of comprehensive error compensation is presented. The comprehensive errors can be diminished greatly to improve the profile accuracy by means of error compensation. It is proved in the experiments that the precision requirements of grinding the formed surfaces grooves can be met.

“…Suppose that O is the swing center and O' is the geometric center and they do not coincide with each other. This will lead to a change of the dressing point, and wheel profile error will be inevitable [4]. The position changes of O and O' are shown in Fig.…”

The different uses of NC grinding machine with ganged revolving spindle and the requirements to NC grinding machine for several special uses are discussed. A multifunctional three axes ganged NC grinding machine with patent right is introduced. Its ganged revolving spindle is changeable. Therefore it can meet the requirements of different uses. When the ganged revolving spindle works as headstock spindle, the NC grinding machine can be used for machining cylindrical cam, plate cam, noncircular shaft and so on. When the ganged revolving spindle works as a revolving spindle of dresser, the NC grinding machine can be used for dressing form wheels with multifarious curved generatrices accurately. With simple mechanism, wide flexibility and simple NC programming, it is especially fit for laboratory use. A new-style NC dresser with invention patent right is also introduced.

“…They can be form grinded, but form wheel needs dressing. So 2 moving axes & 1 rotating axis ganged NC dresser is developed [2]. The grooves' section curves are often described by tabulated curves, their smoothing are usually using Double Circular Arc Method etc., in which curve is described by set of tangent arcs, the calculations are complicated and can't meet quickly response need in production.…”

Approximate Double Circular Arc Interpolated Method which was put forward by author, is different from other circular arc interpolated methods in demanding only the corner between normal directions of each circular arcs at intersection point are less than designated allowed value but not demanding contiguous circular arcs are tangent, and makes the calculating be predigested. In order to estimate error of the method, emulated calculating is carried out, namely the course of curve being obtained by reverse engineering is simulated in this paper. The results show: if space between measure points is about 0.1mm in curve being obtained by reverse engineering, then, the most departure of smoothing results from original curve is 0.552μm for the stated example. Influence of the error on NC machining is quite small, so it can meet the needs of NC machining.
