5 CHAPTER 1 - INTRODUCTION The Renishaw Tool Touch Probe used on the Hardinge CONQUEST T42 Chucker and Bar Machine allows the operator to set tool geometry offsets quickly and accurately. Once the probe has been installed on the machine and properly calibrated, tool set-ups and changes can be done in seconds. - NOTE - Normally, it is not necessary to redatum the probe unless one of the following occurs: The probe arm has been dropped. The probe tip has been replaced. The machine is operating at a temperature that is significantly different than that which it was datumed at. - PRECAUTIONS - To insure optimum accuracy, the following precautions should be observed: 1. The arm must be kept for a period of time at the same temperature as the machine to be sure the arm is at the same temperature as the machine. 2. The machine should be at its normal operating temperature. 3. When datuming or tool setting is being performed, the arm should be stored inside the machine enclosure, in a safe location. 4. After tool setting or datuming has been completed, the arm must be removed from the machine and stored in a clean safe environment. 5. Do not lift the arm except at its base or otherwise mishandle the arm. Although the arm is ruggedly constructed, any stress applied to it may affect its calibration. 6. All procedures outlined in the Hardinge Datuming and Tool Setting Instructions must be strictly adhered to since many of the sequences can affect the safe and accurate operation of the machine if not followed. 7. If there is a conflict between the Renishaw documentation supplied with the probe system and the Hardinge documentation, the Hardinge documentation will apply. M

6 PARAMETER SETTINGS As shipped from the factory, machine parameters 5015 through 5018 are set for the tool probe option. However, before the probe is datumed, the parameter values should be checked to verify that they are correct. Parameters 5015 through 5018 are 8-bit parameters. All eight bits of each parameter should be set to zero. If the parameter values are correct, proceed with the Datuming Instructions in Chapter 2 of this manual. If the parameter values are not correct, use the procedure beginning below, entitled MODIFY PARAMETER SETTINGS, to set each parameters to the correct value. TO VERIFY PARAMETER SETTINGS 1. Press the DGNOS/PARAM function key on the MDI/CRT panel. 2. Press the PARAM soft key. 3.
