Abstract

The illustrated clamp provides a means to reduce casting vibration that normally occurs during a servo process through a unique method. Typically, a file casting is supported and clamped at three points. Any support points would result in distortion of the casting since additional support points would likely outside of the plane surface defined by the initial points. At the same time, the file base casting characteristics benefit significantly from clamp locations. The clamp shown provides clamping without inducing distortion of the base This is achieved by creating the additional clamps that their direction of force is perpendicular to the three clamp points and in a direction of high base rigidity. Thus, the additional clamp points inhibit motion while inducing no measurable base casting

Compliant Clamp

       The illustrated clamp provides a means to reduce casting
vibration that normally occurs during a servo process through a
unique method.  Typically, a file casting is supported and clamped at
three points.  Any support points would result in distortion of the
casting since additional support points would likely outside of the
plane surface defined by the initial points.  At the same time, the
file base casting characteristics benefit significantly from clamp
locations.  The clamp shown provides clamping without inducing
distortion of the base  This is achieved by creating the additional
clamps that their direction of force is perpendicular to the three
clamp points and in a direction of high base rigidity.  Thus, the
additional clamp points inhibit motion while inducing no measurable
base casting
