TP200 introduction

The TP200 / TP200B is a 13.5 mm diameter touch-trigger probe with the facility to quickly change stylus configurations without the need for requalification. Electronic strain sensing techniques are used to improve on the form measuring accuracy and operating life that can be achieved compared with kinematic touch-trigger probes. The TP200 probe is a two piece design comprising the probe body and a detachable stylus module that holds the stylus assembly. The stylus module has a choice of fixed overtravels: ‘SF’ (standard force) or ‘LF’ (low force). There is also the ‘EO’ (extended overtravel) module which has the same overtravel force as the ‘SF’ but provides increased operating range and protection in the probe Z axis. The optional SCR200 stylus change rack provides storage for pre-qualified stylus assemblies and facilitates automatic stylus changing under measurement program control. The probe and rack are powered by the dedicated PI 200-3 interface, which performs signal processing and communicates with the CM M co nt ro ller.

TP200 product description
Probe body
The TP200 probe body houses the strain sensing structure and electronic processing circuitry. When the stylus contacts the workpiece, in a normal gauging move, the force applied to the stylus tip is transferred, through the stylus module and the coupling at the front of the probe body, to the silicon strain sensors. A tip deflection of a few m is sufficient to trigger the probe. The probe’s signals are amplified and processed in a hybrid microcircuit electronic assembly. The probe’s data and control signals are communicated between the probe and the PI 200-3 interface over a pair of screened wires, allowing the TP200 system to be compatible with the majority of Renishaw probe heads and accessories. The TP200B probe body uses the same technology as the TP200 probe body but has been designed to have a higher tolerance to vibration. This helps to overcome the problem of ‘air’ trigger generation which can arise from vibrations transmitted through the CM M or when using long styli with fast positioning speeds.
NOTE: Renishaw does not recommend the use of TP200B with the LF module or cranked / star styli.
The stylus module is held in position on the front of the probe body by a magnetic, kinematic coupling. The coupling allows the stylus module to be removed and then replaced such that the stylus tip returns to a highly repeatable spatial position, eliminating the need for req ualif icat io n.

Stylus module
The stylus module carries the M 2 stylus mount and provides overtravel in the X, Y and + Z probe axes. Overtravel in the -Z probe axis is accommodated by separation of the module from the probe body. There are three modules available, with two different overtravel forces: 1. The SF (standard force) module is suitable for most applications. 2. The LF (low force) module is recommended for use with small precision ball styli or on delicate materials. 3. The EO (extended overtravel) module is recommended for use when increasing the speed of the CM M may lead to stopping distances
which exceed the overtravel range provided in the SF / LF modules. The EO module has an additional 8 mm of overtravel in the probe Z axis to protect against damage to the probe body in such circumstances. Overtravel force is the same as the SF module. The module houses the mating half of the magnetically held kinematic coupling (see ‘Assembling a stylus on a stylus module’), which ensures repeatable positioning on the probe body. The coupling consists of three bearing points formed by the V grooves on the rear of the stylus module, which seat on three ball bearings located on the front of the probe body. The fourth V groove and semi-recessed ball form an alignment feature to ensure that the module has a unique orientation in the rotational axis. The module and stylus axis will be visibly misaligned if the coupling is not correctly seated. Alignment symbols are provided to assist manual alignment. The module cover forms a sliding ring (see ‘Probe body’), which transfers excess force to the case of the probe body if the maximum Z axis overtravel distance is exceeded.
PI 200-3 interface
The PI 200-3 interface unit powers and services the TP200 / TP200B probe and up to two SCR200 stylus change racks. The PI 200-3 will service kinematic switching probes (TP2, TP20, TP6), in addition to the TP200 / TP200B. The PI 200-3 automatically recognises the probe type, determines the status of the probe and transmits probe trigger signals to the CM M controller. When automatic stylus changing is performed using the SCR200 change rack, the PI 200-3 inhibits probe triggering and resets the TP200 / TP200B probe to account for the loading effects of the new stylus assembly on the strain sensors. In the event of rack overtravel or error condition, the PI 200-3 transmits signals to the CM M controller to stop CM M motion. During high speed position moves (fast traverse), it is necessary to reduce probe sensitivity to prevent vibration causing unwanted triggers. The CM M controller automatically switches the PI 200-3 into a low sensitivity mode, such that vibration triggers are prevented. However, a trigger is still issued to stop CMM motion, if an unexpected collision occurs. This mode is known as `probe damped mode’ and is indicated by an LED on the PI 200-3 front panel.
NOTE: The probe cannot take accurate points when damped mode is selected.
The CM M manufacturer sets the configuration of the PI 200-3 and it should not be necessary for the user to make adjustments except to operate the reset button, as explained later in this handbook.

SCR200 stylus change rack
The SCR200 holds and protects up to six stylus modules for automatic changing. The modules are magnetically held in the docking ports, which allows the rack to be mounted in any orientation and eliminates the need for high accuracy positioning. No special commands are necessary, as stylus changing requires only simple position moves to be programmed. The SCR200 incorporates a system of infrared light beams and a Hall effect sensor to detect the presence of the probe and to signal to the PI 200-3 interface that stylus changing is in progress. A self-test mode checks operation of the light beams during power- up. The rack is provided with an overtravel mechanism to reduce the possibility of damage should a collision occur. When the mechanism is deflected, signals are transmitted to the CM M controller to stop CM M motion. The overtravel mechanism is self-resetting. After a collision, the rack should return to its normal operating position and should not require re-datuming.

TP200 probe operation

The TP200 probe has two normal operating states – armed or triggered. The probe should be in the armed state except for the moments when the stylus is deflected against the workpiece.
Probe armed
When the probe is armed sometimes called seated’ orreset’ the following PI 200-3 front panel indicators will be ON: POWER ON TYPE – TP200 PROBE – SEATED
Additionally, the probe head LED will be ON and the LEDs on the TP200 probe body will be OFF. The probe LEDs may sometimes glow slightly, indicating a low level of background vibration.
Probe triggered
When the stylus touches the workpiece the LEDs on the probe body turn ON brightly. The SEATED and probe head LEDs will turn OFF. The probe should be allowed to remain in the triggered state only for the minimum time necessary to reverse the CM M motion and back-off from the workpiece. If the probe remains in the triggered state for more than 10 seconds, drift of the stylus zero reference position will occur and the PI 200-3 will emit an audible warning. Back-off the probe from the workpiece and refer to ‘Resetting the probe’.
Changing a stylus module manually
Ensure the CM M will remain stationary, in a safe condition. Remove the stylus module and store safely. To fit another module, refer to the ‘M ounting the stylus module to the probe body’ section. When using M H8 or M IH probe heads, unlock and relock the head before resetting the probe. Reset the probe, refer to the ‘Resetting the probe’ section.
Operation with a manual probe head
After manually re-orientating the probe when using PH1, M H8 or M IH probe heads, reset the probe. Refer to the ‘Resetting the probe’ section.

Stylus module selection
The SF module is satisfactory for the majority of applications and provides the maximum stylus carrying capability. The LF module should be employed where the application necessitates the use of styli with ball diameters less than 1 mm, particularly the PS29R (Renishaw part number A-5000-7800), or where lower overtravel force will reduce the risk of marking or deflecting the surface of the workpiece. The EO module is recommended for use when increasing the speed of the CM M may lead to stopping distances which exceed the overtravel range provided in the SF / LF modules.
NOTE: The overtravel force, in the X-Y axis, varies with both direction and displacement for a given stylus length. In the X-Y axis there is a pattern of three maximum and minimum force directions as illustrated in figure below:

Stylus selection

To obtain the best performance apply the following considerations when selecting and fitting a stylus: Use the shortest possible stylus length M inimise the mass of the stylus by using the types with ceramic or GF stems where possible – refer to the Renishaw stylus catalogue for further information Work within the recommended stylus limits Ensure that stylus balls, threads and mating faces are kept clean Tighten styli using only the tools provided Use the stylus changing facility to optimise the styli for accuracy and feature access Always qualify the styli at the gauging speed set for the part measurement program. If the speed is changed re-qualify the stylus tips

Issued 02 2024

24

TP200 user’s guide
www.renishaw.com

Recommended stylus limits
The absolute maximum stylus carrying ability of the TP200 probe is determined by the mass of the stylus and the distance from the stylus holder to the centre of gravity. The limits are:

Low force module 3 g at 20 mm

Standard force module 8 g at 50 mm

In practice, the stylus carrying is restricted by CM M vibration level, probe orientation and CM M controller flexibility. The recommended limits are given in the figures below.
It may be possible to exceed the recommended limits but the user is advised to conduct trials to establish the suitability for the application and the effect on measuring performance.

Trigger level
Under certain conditions, vibration may cause false `air’ triggers during gauging and it may be necessary to reduce the probe sensitivity. False triggers may occur when large or heavy stylus arrangements are used, or where there is floor transmission from nearby machinery or vehicles.
Trigger level 1 – the highest sensitivity mode, provides the best measuring accuracy Trigger level 2 – lower sensitivity to vibration but with a small loss of measuring accuracy The trigger level is selected by switch 10 on the rear panel of the PI 200-3 interface: Level 1 – switch 10 DOWN Level 2 – switch 10 UP
NOTE: For versions of the PI 200-3 prior to V9, the trigger level was adjusted by switch 11.
The trigger level selection does not affect sensitivity when the probe is in damped mode. Please consult your CM M supplier before making any adjustment to the PI 200-3 settings. All stylus tips must be re-qualified after changing the trigger level.

SCR200 rack operation
Operating modes
The SCR200 may be operated in either of two modes depending on the application requirements and whether the SCR200 is accessible in normal operation. With TAM PER PROOF ON selected, the stylus change cycle is initiated by moving the probe across the face of the Hall sensor, for the rack to detect the presence of the probe before entering a docking port. In this mode, interruption of the light beams alone does not inhibit probe triggering and therefore the probe cannot be accidentally inhibited during normal operation. For example by placing fingers in the light beam or by operating a port lid. With TAM PER PROOF OFF selected, direct entry to the rack ports is allowed. The light beams detect the probe entering a module docking port and inhibit probe triggers. In this mode faster stylus changing is possible but Renishaw recommend that it is used only in situations where access to the rack is restricted when the CM M is operating automatically.
To select the operating mode
Remove the electrical connector M ove the mode selection slide switch (see ‘M ounting the SCR200 rack on the CM M ‘) – LEFT for tamper proof ON, RIGHT for tamper proof OFF Replace the electrical connector Confirm that the POWER and STATUS lamps are indicating the correct mode
Loading stylus modules into the rack
Renishaw recommends that the stylus modules are mounted on the probe body by hand. An automatic stylus change routine is completed prior to tip qualification then the stylus module is loaded into the rack. The CM M should be used to load the stylus modules into the rack by following the ‘Stylus module changing procedure’. It is possible to load the rack by hand but care must be taken to ensure correct rotational alignment, as there is no warning if a module is incorrectly seated on the probe sensor and gross measurement errors will occur.

Stylus module changing procedure
Storing a stylus module – tamper proof ON
Refer to the ‘Datuming the SCR200 rack’ section for definitions of coordinate X(n), Y, Z. 1. M ove to the START coordinate for activating the Hall sensor: {Xs, Ys, Z}, where Xs = X1 + 82 mm and Ys = P3 + R (1 mm) – 7.5 mm. 2. M ove along the X- axis to: {Xs – 12 mm} at a minimum speed of 5 mm/ s. 3. M ove along the X axis to the centre line of the required vacant port (n): {X(n), Ys, Z}.
NOTE: If the stylus assembly has an offset or star component projecting along the Y+ axis, it is permissible (after step 1) to move out along the Y- axis and exit the light beam for a maximum of 5 s, to avoid a collision with the SCR200 leg or another stored st ylu s.
4. M ove along the Y+ axis to the docking target coordinate for port (n): {X(n), Y, Z} 5. M ove along the Z+ axis to the release coordinate: {X(n), Y, Zr} where Zr = Z + 3 mm. 6. M ove along the Y- axis to a coordinate clear of the port lid: {X(n), Ys, Zr}

Storing a stylus module – tamper proof OFF
Refer to the previous procedure (‘Storing a stylus module – tamper proof ON’) omitting steps 1 and 2. NOTE: It is not necessary to stop CM M motion at the start coordinate in this mode, provided that the port is entered along the Y+ axis at the specified X(n) and Z axis positions.

TP200 maintenance

TP200 probe body and stylus module
The kinematic coupling mechanism, connecting the probe body to the stylus module, incorporates precision ball / V groove seatings. The coupling mechanism has been tested in a wide range of environments and is highly tolerant of non-metallic dust, but regular inspection and cleaning with the CK200 material (supplied) is recommended to ensure continued high performance. Instructions for use are included with the cleaning material (Renishaw part number A-1085-0016). The user should determine the frequency of cleaning according to the conditions of use. Stylus balls, threads and mating faces should be cleaned with a proprietary cleaning cloth or solvent. Stylus modules that are not in use should be stored in spare ports in the SCR200 rack or in their transport boxes.
SCR200 rack
Periodic cleaning of the rack ports, lids and outer surfaces using a proprietary cleaning cloth, is recommended to prevent contamination of the modules.
