Section 1: Stylus System Changer Setup for Scanning CMMs with Vast, or Vast-XT Scanning Heads.

1. Affix the Stylus System Changer to the CMM table using the bolts accompanying the changer

in the desired orientation. The most common orientation is on the backside of the CMM facing the front, however the changer may be installed in any axis direction: X, -X, Y, or –Y.

2. Align the changer to the machine axis. This is done by one of the following:

A. Drive the stylus system using the joysticks along one of the machine axes, making adjustments to the changer as needed so that when adjustments are complete, the stylus system drives parallel to the changer.

B. Take a manual probing point on the front face at either end of the changer and compare the positions in X and Y. Make adjustments until the changer has minimal deviation in the machine axis direction (X or Y).

3. Tighten changer bolts firmly to prevent movement. 4. Define the Master Probe length.

A. In the CMM tab, Click the Stylus System Icon.

B. In the Stylus System screen, click the Stylus System Changer Icon.

C. Click the Length of Master Probe button.



D. Calypso will prompt you to probe the adapter plate (the plate through which the Master Probe is attached to the probe head) on the top of the changer bay and then probe the same surface with the ruby stylus tip. The Master Probe Length will then be displayed.

5. In the Changer dropdown, select Approach Parameters and change the approach direction to

the correct changer orientation.

6. To add a holder, click the Edit dropdown and select Add Holder. Names may be given to

each holder position created. Up to 15 holder positions may be created. 4.2 users: Define the type of Holder; in this case choose MT.

7. Click on the first holder (holder position will turn green when selected) and click the Changer

dropdown. Choose Define Holder Location. 8. Drive the Master Probe to the changer bay that is to be defined. Position the Master Probe

just above the spherical pocket located on the right side of the bay. Follow the user prompts in Calypso to define the holder location. The holder is located by a self-centering point taken by the Master Probe in the holder pocket. Repeat steps 7 and 8 for all holder locations.

In the Stylus System Changer screen, select a holder position and, from the Changer dropdown, select Set Stylus System to Holder. From the list, choose a stylus system for each holder position.



Section 2: RDS Adapter Plate Changer Setup for Rotating Head CMMs (NOT RDS-CAA).

Note: Determining RDS-Geometry must only be done if the stylus system changer is being

installed for the first time. The master probe must be qualified in all 5 positions before the RDS stylus system changer can be defined. 1. Perform a manual stylus system change to install the Master Probe and find the Reference

Sphere Position. After the reference sphere has been located, qualify the preset stylus positions.

2. If the refPos positions for the Master Probe have not yet been qualified, the positions must be

created using the Rotate Stylus to New Position button with the information in the following chart:

• RefPos1: A/B = 0°/90° Stylus number 2

• RefPos2: A/B = 0°/–90° Stylus number 3

• RefPos3: A/B = 90°/0° Stylus number 4

• RefPos4: A/B = –90°/0° Stylus number 5

3. After all reference positions have been created, click the CNC Qualification button in the

upper right hand corner of the Stylus System screen to qualify all positions.



4. Open the Automatic Stylus System Changer and click the Determine RDS-Geometry button in the upper right hand corner.

5. With the RDS head articulated to a qualified position, align the outer slot surface of the adapter plate with the plane of the stylus system changer. SEE PICTURE BELOW:



6. Click on the Read Position button. The X, Y, and Z coordinates should appear in the respective fields.

7. Drive the Stylus System away from the changer and click Apply. The head will rotate 180 about

the A axis. 8. Using the same adapter plate slot surface and changer plane, align the adapter plate with the

changer surface. With the surfaces aligned, click Read Position in Section 3.

9. The Slot Distance will be calculated and appear in the Slot Distance field. This value should be

around 38.0000mm and can be modified to allow for smoother operation.



10. To add a holder, click the Edit dropdown and select Add Holder. Names may be given to each

holder position created. Up to 15 holder positions may be created. 4.2 users: Define the type of Holder; in this case choose RST. Before the holder locations can be defined, the orientation of the stylus system changer must first be defined. 11. In the Changer dropdown, choose Approach Parameters. In the Approach Direction dropdown,

choose the direction perpendicular to the changer. This direction is NOT the direction the CMM will travel in while installing or removing the adapter plate.

ie: If the changer is installed on the back side of the CMM, the head must travel in the +Y direction towards the changer and will rest just to the left of the holder position. To remove the adapter plate from the RDS head, the head must then move in the +X direction. The Approach Direction is +Y (the primary direction taken to travel to the changer).



12. To define the holder location, choose the holder to be located and select Define Holder Location from the Changer dropdown.

NOTE: The RDS head must be rotated to the position needed to enter the holder (the roller should contact the RDS head on the side opposite the adapter plate). 13. Follow the prompts provided by Calypso to locate the holder position. The first probing point will

be taken manually on the top of the raised cube on the back corner of the holder.

Figure 1: Location of raised cube on holder

Following the manual probing point, the Master Probe will finish locating the raised cube automatically.



14. Once the position of the holder has been defined, verify the position by storing the Master Probe into the newly-defined holder. In the Stylus System Changer screen, select the defined holder (the holder will turn green when selected), and in the Changer dropdown select Remove Stylus System.

BE CAREFUL! Load the probe into the holder slowly for the first time, making sure the

alignment of the adapter plate to the holder is correct. If the alignment is incorrect, turn the speed control knob on the joystick box all the way down to stop the CMM motion. Navigate to the Stoplight and click the red light followed by the green light. This will allow the user control of the CMM again. 15. Repeat Steps 9 through 11 until all holders have been defined. 16. In the Stylus System Changer screen, select a holder position, click the Changer dropdown, and

select Set Stylus System to Holder. Choose the stylus system for each holder.



Section 3: Stylus System Changer Setup for VAST xxt 1. Affix the Stylus System Changer to the CMM table using the bolts accompanying the changer in

the desired orientation. The most common orientation is on the backside of the CMM facing the front, however the changer may be installed in any axis direction: X, -X, Y, or –Y.

2. Align the changer to the machine axis. This is done by one of the following:

A. Drive the stylus system using the joysticks along one of the machine axes, making adjustments to the changer as needed so that when adjustments are complete, the stylus system drives parallel to the changer.

B. Take a manual probing point on the front face at either end of the changer and compare

the positions in X and Y. Make adjustments until the changer has minimal deviation in the machine axis direction (X or Y).

3. Tighten changer bolts firmly to prevent movement. 4. Define the Master Probe length.

A. In the Prerequisites List, Click the Stylus System Icon. B. In the Stylus System screen, click the Stylus System Changer Icon.

C. Click the Length of Master Probe button.



5. Calypso will prompt you to probe the adapter plate (the plate through which the Master Probe is attached to the probe head) on the top of the changer bay and then probe the same point with the ruby stylus tip. The Master Probe Length will then be displayed.

6. In the Changer dropdown, select Approach Parameters and change the approach direction to the

correct changer orientation.

7. To add a holder, click the Edit dropdown and select Add Holder. Names may be given to each

holder position created. Up to 15 holder positions may be created. 4.2 Users: Define the type of Holder; in this case choose XXT.

8. Click on the first holder (holder position will turn green when selected) and click the Changer

dropdown. Choose Define Holder Location. 9. Drive the Master Probe to the changer bay that is to be defined. Position the Master Probe just

above the spherical pocket located on the right side of the bay. Follow the user prompts in Calypso to define the holder location. The holder is located by a self-centering point taken by the Master Probe in the holder pocket. Repeat steps 7 and 8 for all holder locations.

10. In the Stylus System Changer screen, select a holder position and, from the Changer dropdown,

select Set Stylus System to Holder. From the list, choose a stylus system for each holder position.



Section 4: Defining Approach Parameters In the Changer dropdown, select Define Approach Parameters.

Adjust the position before, over, and after holder so stylus system will clear the changer during stylus system changes. NOTE: This must be done for each holder. You may have to make changes to holder approach parameters for various stylus systems. If you find the need to move a stylus system to another changer holder, you will have to change the approach parameters for the new stylus location. The approach parameters apply to the HOLDER not the Stylus System!
