Toolsetting frame and cutting process.
Background technology
Since monocrystal material has the anisotropy of mechanics and physical property, after Vehicle Processing, the circle of monocrystal material
The processing quality of all outer surfaces can also be not quite similar.For certain monocrystal materials, extremely strong brittle property can be also shown, is passed through
After crossing the turning of single-point diamond cutter, or even it can be cracked in finished surface.
During actual cut, the machining of monocrystal material is typically to be completed under identical stress condition, still
Since plastic deformation ability of the monocrystal material on different crystal orientations is different, cutting force can be caused to generate fluctuation with crystal orientation
The phenomenon that, the fluctuation of this cutting force also results in surface quality and fluctuates, and crisp modeling may occur in some crystal orientation and turn
Become phenomenon, since the surface roughness after processing has differences, to which light and dark sector distribution characteristics be presented.
And many because being known as of monocrystal material suface processing quality are influenced, wherein diamond cutter geometric parameter and processing
Technological parameter can all influence suface processing quality.For example, when cutting monocrystalline silicon using diamond cutter, before suitable bear
Angle, smaller cutting edge roundness and smaller cutting depth can be easier to obtain uniform finished surface.
In order to realize the clamped one time of cutter, raising processing efficiency, and smaller tool edge radius is selected, then according to single
The brilliant distinctive mechanical characteristic of material, is combined using best tool orthogonal rake and optimal cutting depth, and it is equal just to process surface
Even consistent monocrystal material workpiece.
But be combined to find suitable best tool orthogonal rake and optimal cutting depth, it needs in process
In to cutter carry out repeatedly clamping can just find suitable combination to adjust the processing anterior angle and cutting depth of cutter.But
It is that clamping cutter will seriously affect processing efficiency repeatedly, while clamping also needs to again to knife and centering every time, this is to processing essence
Degree, which also will produce, to be seriously affected.
Currently, being broadly divided into two classes for the fast servo tool of monocrystal material cutting, first kind servo saddle only can
Change Tool in Cutting depth in process, the second class servo saddle can only change tool sharpening anterior angle.Although above-mentioned two
Class servo saddle can improve the machined surface quality of monocrystal material to a certain extent, but the factor for influencing surface quality is not
Single, since above-mentioned two classes servo saddle can only all meet the adjustment of single parameter, it can not further increase list
The machined surface quality of brilliant material.
