The main difference between the two types is that the PH9A has the facility to automatically select probe combinations and extensions without having to requalify the probe. This 'autojoint' facility can also be used manually as a 'quick change' method of exchanging probe combinations. Section 2 describes both systems and the options available. Figures 1 and 2 show typical installations for the PH9 and PH9A respectively. These are followed by a description of each of the component parts and their functions. The main part of this user's guide describes how the systems should be used in manual and automatic modes. A list of possible operating errors is given, which is followed by specifications for the PH9 and PH9A probe heads. Installation and programming of the systems is described in the PH9 and PH9A Installation and Programming Guide (Part No. H-1000-5065). If you require further information on options available and forthcoming, contact your Renishaw distributor.

Under control of description a CMM computer, the PH9/9A heads permit unsupervised operation using any combination of the 720 positions available. The heart of the system is the motorised probe head itself, which will repeatably locate a stylus ball to within ±0.5µm of a previously qualified position (see Section 6.0 for specifications of the PH9 and PH9A). Figure 3 shows the versatility of both the PH9 and PH9A probe heads. The PH9 motorised probe head can be used to inspect intricate and complex features, deep with a workpiece. Its compact dimensions mean that it can often be regarded as an extension of the machine quill. 22 PH9/PH9A User's Guide PH9/PH9A AUTOMATED INSPECTION SYSTEM 2.1 General description Figure 3 - PH9 and PH9A automated inspection systems PH9/PH9A User's Guide 23 PH9/PH9A AUTOMATED INSPECTION SYSTEM 2.2 Figures 1 and 2 show examples of PH9 and PH9A systems. The various items shown have been numbered to make the system easy System to understand and follow. The following describes the component components parts of the system in numerical order. 1 Stylus The function of the stylus (see Figure 4) is to hold the ruby ball rigidly in position while it touches a workpiece surface. It transmits a movement triggering the probe when it is deflected. An extensive range of styli is available (see brochure H-1000-3200). Figure 4 - Example stylus 2 Probe The Renishaw probe (see Figure 5 ) is the most important fundamental part of the system. The probe is the device which signals to the CMM that a contact has been made between the stylus ruby ball and a workpiece surface. The precise coordinates at the point of contact can therefore be read and stored by the CMM. (A range of probes is available to suit most applications, see Probing System for Coordinate Measuring Machines Technical Specifications, Part No. H-1000-5050.) Figure 5 - Example probe 24 PH9/PH9A User's Guide PH9/PH9A AUTOMATED INSPECTION SYSTEM 3 Extension bar 2.2 Extension bars (see Figure 6) are designed primarily to extend the System range and depth of probing, particularly inside large and complicated components workpieces. The PH9 and PH9A can carry a range of extension bars continued (see Section 3.2). Figure 6 - Example extension bar 4 PH9 and PH9A motorised probe heads The PH9 and PH9A probe heads are designed to position a probe in any one of 720 positions in steps of 7.5°. There are 15 discrete positions through 105° in the A axis and 48 positions through ±180° in the B axis (see Figure 7). Figure 7 - PH9A probe head assembly PH9A probe head ±180° rotation in B axis autojoint 105° rotation in A axis PH9/PH9A User's Guide 25 PH9/PH9A AUTOMATED INSPECTION SYSTEM The vast number of alternative positions means that probing can be 2.2 carried out from many different angles. A high degree of positional System repeatability is achieved every time (thus avoiding the need to components requalify when the probe is returned to a previously qualified position). continued The PH9/9A probe heads are controlled by three electric motors. One drives the A axis, one the B axis and the third locks and unlocks both axes. Slipping clutches are fitted to the axis motors to prevent damage to the drive system in the event of a collision during movement. The kinematic locations which position the head accurately when locked up are also used to detect a failure to lock correctly (datum error), and probe crashes (overload error). Accidental rotation of the head beyond its normal range in both axes is prevented by overtravel stops. The main difference between PH9 and PH9A is the joint attachment of the probe. On the PH9 swivel there is an M8 bush. Probes and/or extension bars are manually screwed into this bush before the system is used. When different combinations of probes and/or extensions are needed, these are changed by hand. The PH9A, however, has an autojoint (A for autojoint) which allows probes and extension bars to be selected from the autochange rack under program control, or 'quick changed' manually. Once the CMM has been programmed, there is little need for any human intervention, thus taking the machine one step closer to the fully automatic inspection system. Figure 8 shows how the two halves of the autojoint connect together to give a high level of repeatability. Figure 8 - Autojoint PEM1 extension bar S10 autojoint key TP6 probe 26 PH9/PH9A User's Guide PH9/PH9A AUTOMATED INSPECTION SYSTEM The signal from the touch trigger probe is routed through the contacts 2.2 on the autojoint into the probe head and then through the 14 pin plug System at the top corner of the head to an interface via the PHC9 controller components (see Figures 1 and 2). continued 5 Adjustment module AM1 The Renishaw adjustment module AM1 shown in Figure 9 enables accurate alignment of any motorised probe head with the machine quill, or the alignment of the probe assembly to the workpiece. In an autochange system it must be fitted to achieve the required alignment of the probe head with the autochange rack ports. The AM1 also has a quick release mechanism to install and remove the attached motorised probe head. Limited additional overtravel protection is provided with this module. Figure 9 - Adjustment module AM1 PH9/PH9A User's Guide 27 PH9/PH9A AUTOMATED INSPECTION SYSTEM 6 Shanks 2.2 Renishaw provide an extensive range of shanks to fit most makes of System CMM. See Figure 10 for an example of a Renishaw shank. components continued Figure 10 - Example shank 7 Cables Various types and lengths of cables are supplied by Renishaw. Contact Renishaw or your CMM supplier for details. 8 PHC9 Probe head controller The PHC9 probe head controller shown in Figure 11 receives instructions from the CMM computer in either serial (RS232) or parallel (IEEE488) form (note that the appropriate version must be purchased). It controls all probe head functions and reports the system status to the CMM. Software designed for the PH9/9A system is directly compatible with that required by the PH10M system, which means that the same software can be used without modification if an inspection system is upgraded from PH9/9A to PH10M. Figure 11 - PHC9 probe head controller See Section 4.4 for full details of the PHC9 probe head controller. 28 PH9/PH9A User's Guide PH9/PH9A AUTOMATED INSPECTION SYSTEM 9 PHD10 Probe head drive unit 2.2 The PHD10 (see Figure 12) is a remote hand control which allows the System probe head to be used in manual mode. It is used during setting up components and operator controlled inspection cycles and is an invaluable tool for continued programming using the 'teach cycle' method. The unit has four buttons which can be used to orientate the probe in both A and B axes in increments of 7.5°, and a T button which can be used to transmit positional information to the controller. The position of the probe head is displayed on the drive unit in degrees. Three LEDs on the unit show the status and error conditions. The PHD10 supersedes the PHD9 and is functionally identical except that it will drive up to 15m of cable as standard. No damage will occur if the old PHD9 is connected to the PHC9, but it will not function. Figure 12 - PHD10 probe head drive unit See Section 4.3 for details on how to use the PHD10 to control the system manually. PH9/PH9A User's Guide 29 PH9/PH9A AUTOMATED INSPECTION SYSTEM 10 Interfaces 2.2 Renishaw recommend that a suitable probe interface is used for all System installations (both new and retrofit) to enable users to expand the components system in the most efficient way. If interfaces in the Renishaw range continued such as the PI4-2 or PI200 are used, different interconnection cables may be required. 11 Autochange rack and 12 ACC2 Autochange controller (for use with PH9A only) The Renishaw autochange system is the next step towards turning the CMM into a flexible inspection system. The capabilities of the CMM are increased to a point where there is no need for human intervention even where very complex inspection cycles are required. It is ideal for applications where complex parts are to be inspected automatically and where probe types, extensions and/or accessories are to be changed several times. Once the machine has been programmed, a great deal of time and effort can be saved, as this automatic probe exchange system does not require requalification of probes when returned to the autochange rack and subsequently re- selected. 30 PH9/PH9A User's Guide SETTING UP THE SYSTEM 3.0 SETTING UP THE SYSTEM The PH9/9A is designed to be mounted in any orientation, using a 3.1 standard shank to suit your machine. Setting up using The PH9/9A can also be fitted with the AM1 adjustment module (see adjustment Figure 13). This allows fine adjustment of the head in pitch, roll and module AM1 yaw, enabling the head to be accurately aligned with the machine's axes (this is particularly important when using an autochange rack ). The AM1 incorporates a bayonet fitting, allowing the head to be easily detached from the machine and to be refitted. Pitch adjustment Rotate the pitch adjusting capstan to alter the pitch. Roll adjustment Rotate the roll adjusting capstans an equal amount in opposite directions to alter the roll. The roll adjustment range is ±2°. Yaw adjustment 1. Release the lock/unlock screw. 2. Release one yaw adjusting screw and tighten the other to achieve the yaw required (the yaw adjustment range is ±5°). 3. Tighten the yaw adjusting screws against each other without applying excessive torque. 4. Tighten the lock/unlock screw.

This is repeated for all the required positions. The system carries out the programmed inspection cycle without having to requalify any of the positions. This is because of the high repeatability factor (i.e. better than ±0.5µm at the stylus tip - see Section 6.0 for details). An additional error of up to ±0.5µm is possible when probe/extension combinations are automatically exchanged during an inspection operation using the PH9A. PH9/PH9A User's Guide 37 SYSTEM OPERATION 4.1 Using the PH9/9A WARNING inspection Pinch hazards exist between moving parts and between system moving and static parts. Do not hold the probe head during continued movements, or during manual probe changes. Beware of unexpected movement. The user should remain outside of the full working envelope ! of probe head/extension/probe combinations. In all applications involving the use of machine tools or CMMs, eye protection is recommended. CAUTION The PH9 and PH9A must only be used with PHC9 controller. Do not attempt to interact these systems with ! PH10M (PHC10-2) equipment as damage may occur and the warranty will be invalidated. 4.1.1 Checks Once the system has been installed, check the following points: 1. Ensure that the correct connections and settings have been made. 2. Check that the PH9/9A probe head and the AM1 adjustment module are securely mounted. Do not apply excessive force to any of the moving parts of the PH9 or PH9A probe head as this can cause excessive wear and/or internal damage. Take care to avoid a probe head collision as this could cause severe damage to the head. 38 PH9/PH9A User's Guide SYSTEM OPERATION 4.1.2 Power-up sequence 4.1 The order in which the various units (e.g. controller, interface etc) are Using the switched on is not important. PH9/9A inspection The PHC9 controller initiates the following action on the PH9/9A when system switched on: continued 1. If the PH9/9A is not locked up it will go to its nearest position and lock up. 2. If the PH9/9A is locked up and the system is in manual mode, position 0,0 will be displayed on the PHD10 probe head drive unit irrespective of the actual position of the probe head. If any of the direction buttons are pressed, the PH9/9A will first move to the 0,0 position but will not lock up. Only then will it move to the position requested by the PHD10 probe head drive unit. 3. If the PH9/9A is locked up and the system is in automatic mode, the PH9/9A will begin to move towards the 0,0 position, but before reaching that position, it will change direction and move to the position requested by the CMM program. CAUTION Renishaw recommend that the PH9/9A completes its program and is parked in the 0,0 position before switching ! off the power. This will prevent rapid movement of the PH9/9A when the system is switched on again.

Inspection is continuous, without the need for repeated inspection qualification cycles. system continued With the ability to orientate the probe in angular steps of 7.5°, holes or faces at any angle can be measured (see Figure 19). The maximum misalignment between stylus stem and component need only be 3.75°, and this is easily accommodated by the ball stem clearance. If it is necessary to measure the diameter of a deep hole or slot, where the stem clearance is insufficient, rotate the probe head through a 7.5° step. This enables inspection of the opposite face. Alternatively, an AM1 adjustment module may be used to align the head/probe/stylus assembly to the feature, but the head may not be used with autochange rack. PH9/PH9A User's Guide 41 SYSTEM OPERATION Figure 19 - Inspection 4.1 Using the PH9/9A inspection system continued 3.75° max. ball/stem misalignment clearance 42 PH9/PH9A User's Guide SYSTEM OPERATION 4.2 CAUTION Automatic It is essential that the CMM is programmed so that mode measurements are not made during error conditions Automatic mode is selected on power up unless the PHD10 probe head drive unit is fitted, in which case manual mode is selected. In automatic mode the PHC9 controller and the PH9/9A probe head are under control of the CMM computer. The sequence of operation is as follows (see Figure 20): 1. Positional data for both the A and B axes is transmitted to the PHC9 controller from the CMM computer. 2. Positional update data is sent from the CMM computer to the PHC9 controller. This initiates a head move sequence. The Head Active LED is switched on and the Head Ready LED switched off. 3. The PH9/9A unlocks, rotates to the required position in both the A and B axes and locks in the required position. 4. A Status signal is sent to the CMM computer from the PHC9 controller indicating that the move sequence is complete. 5. The Head Ready LED is switched on and the Head Active LED is switched off. Figure 20 - Automatic mode sequence required move locked unlock move reach position lock up The Status signal sent will contain information indicating any error which occurred during the head move.

The A and Manual B buttons move the probe up (+A), down (-A), left (-B) and right (+B). mode continued The T (Transmit) button is used to send a signal to the CMM computer. The response to this depends on the CMM computer program (e.g., when the operator is 'teaching' the CMM computer a sequence of positions to follow, the T button can be pressed to signal that a required position has been reached). When the T button is pressed the display momentarily goes blank. This confirms that the instruction code has been successfully transmitted (see PH9 and PH9A Installation and Programming Guide, Part No. H-1000-5065, for details of instruction codes). WARNING Pinch hazards exist between moving parts and between moving and static parts. Do not hold the probe head during ! movements, or during manual probe changes. Beware of unexpected movement. The user should remain outside of the full working envelope of probe head/extension/probe combinations. To move the probe head in single steps: • Momentarily press the direction button (A or B) which corresponds to the 7.5° step required. The head unlocks, rotates 7.5° in the axis and direction chosen and locks up again. To move the probe head rapidly: Press and hold the direction button (A or B) which corresponds to the axis and direction required. The head unlocks, moves one 7.5° step and after a short delay rotates at rapid speed in the direction required until either the button is released or the limit of rotation is reached. Once the button has been released and rotation has stopped, there is a short delay while the head locks up.
