can perform.
Midplane A plane located between two points or lines and perpen-
dicular to an imaginary line connecting them.
Midpoint A point located at the center of a line segment. An
alignment routine that locates the origin for the part’s
coordinate system midway between two elements and
where the Minor axis is perpendicular to the Major axis.
Minor Radius The smallest possible distance between the outermost
edge of an ellipse and its center.
Minus Tolerance The negative amount that an actual measurement can
deviate from its nominal value.
MMC Maximum Material Condition. The condition of a
feature in which that feature contains the maximum
amount of material that is allowed by the toleranced
dimensions (i.e. the smallest hole or the largest shaft).
Moire Fringe An optical principle used on most Coordinate Measuring
machines. It consists of a fixed glass or reflective steel
scale and a moving reader head that counts (measures
distance) as it passes along the scale.
Monitor The video display on a computer. Also a screen.
Movable Component A major structural component of the CMM which is
movable relative to the machine base during measure-
ment.
Multiplier A value that effectively pushes the target point deeper
into the part.
Named Axes The two axes of the machine’s working plane. Same as
Machine Named Axes.
