MM&T. Improved Machining Procedures for Dovetails.
Abstract
The machining of dovetails is a standard practice to the metalworking industry. Over the years a variety of techniques have been tried, each offering limited success. Examples of these techniques include broaching and milling. The broaching process, while it greatly reduces the possibility of machining error by virtue of its tool geometry, requires very expensive specialty equipment that, in most cases, has very little conversion capability. Tool maintenance and capital equipment costs are comparatively high. The milling process using high speed form cutters on the other hand, permits the use of more readily available equipment. This reduces substantially the initial start up cost. One disadvantage of using form mills is the required frequency of tool maintenance. This constantly changes the size of the mills and necessitates continual operator intervention in the operation, consequently increasing the possibility of machining error. This also increases the number of cuts necessary, thereby increasing cost.
