MH3D
The Inspection Process
The first step to approaching a measurement is to review the print or drawing
and identify all dimensions which must be verified. One prefered method is to
highlight all dimensions which must be verified. Once a good understanding of
the measurement task is in place then the setup and fixturing can be identified.
To mount a workpiece for measurement:
• Remove all obstructions from the MH3D’s work table.
• Ensure that the part to be measured does not exceed the machine’s
weight or size capacity.
• Locate the part within the measuring envelope of the MH3D, ensuring that
the sections to be measured are within the probe measuring range and as
close to the operator as possible. If table clamps are used, try to locate the
workpiece conveniently with respect to the M10 threaded table inserts
CAUTION
Do not overtighten clamp bolts or the threaded table inserts may pull
loose from the granite table. The maximum allowable torque on the
bolts is 15 ft. lbs.
Clamping is a very important aspect of planning a measuring strategy yet it is
often overlooked. Incorrect fixturing can lead to part deformation and use up a
significant portion of the part tolerance. The problem is magnified with tempera-
ture variation during the measurement period. It is impossible to define a generic
method for fixturing parts since this will vary due to part geometry, material,
cross section, etc. Let it surfice to say that the clamping or fixturing method
deserves serious consideration when creating an inspection plan. There are many
articles available on designing kinematic clamping / fixturing systems.
