TESA MICRO-HITE 3D Quick reference guide -Last updated 01/30/09 Uncover machine, make sure air supply is hooked up, Turn on machine at left side of touch screen
Press button next to check mark to accept Language default setting Press this button every time the reading taken by the machine is to be accepted
Follow instructions for calibration every time machine is to be used after being off.
First task is to recognize the origin point . Follow instructions on screen
Every axis can be locked in position at any time with switches at vertical sliding arm
IMPORTANT: Push and pull vertical sliding arm every time you move on the Y axis
Accept the default for TTP Probe
Next task is to remove the probe and place Z rail against the sphere
Before you do this, move Z rail close to the current position of the ball
Remove the probe loosening the lever at the right side of Z rail Position bottom of Z rail on top of the sphere and accept the point Reattach Probe to Z rail at the same position it was before (light in front)
Next task is to measure the qualification sphere IMPORTANT: For all following tasks and to measure anything points have to be registered contacting probe to surfaces. To do this, carefully move probe close and make contact with the surface approaching it very slowly and normal to the surface. Do not drag probe across surface.
You need to contact the sphere on five points. First touch the top of the sphere. Next, you need to touch four sides along the “equator” of the sphere, a suggested way to do this is to get the probe in position then lock the Z axis
Contact four points around the sphere Unlock Z axis
Accept reading of Probe tip summary (unless the reading is not within tolerance)
Press button next to Measurement icon
The measurement screen is blank and shows the position of the probe from the origin point established in the beginning, at the front, top left side of the machine
Register four or more points in the granite surface to define a plane for the origin of the Z axis
Accept the reading when the arrow is in the plane icon position
Another way to accept a reading is to push the check mark button in the Z rail
Sometimes a circle is registered when you are trying to define a plane, this is because the software recognizes three or more points as defining a circle as if they were intersecting the circle.
Cancel the circle definition by pressing the button next to icon shown. This icon cancels the last reading registered.
The best approach to avoid registering a circle is to select four points on surface, one of them inscribed inside three points defining a triangular shape
The screen at the left shows how a plane is registered
Press button to define this plane as datum “A” This establishes the origin of the Z axis in this plane
Once you define this plane as a datum, you should see the screen turn to this
Next you need to define the X and Y axis directly on the part you are measuring To do this pick two points first to define the X axis line. First point to be picked must be on the left relative to the other one.
Pick second point
A line is registered in the screen. Accept this
Sometimes you get a screen asking you to establish this selection of points as a plane. Exit the screen and register two points again
Register two points at the left of the part to define the Y axis line
This is what a defined line looks like in the screen
Select the tools icon to establish a relationship between the two lines you picked.
Pick relationships from tools screen (not shown) Pick the two lines you created by selecting the x mark once you highlight every line
Accept the selections and select the button shown at the left, this will establish the intersection of the two lines as origin “C”, which will make the lines to act as X and Y axes
Once established, this is what the new origin looks like
It represents the zero position for the X and Y axes, and combined with the A datum, gives you the 0,0,0 position shown in picture
Now you can start measuring. Select any point in your part and accept it
It usually registers as shown in the screen at left Bottom value “X” shown is the distance from the origin in the X axis.
