Calibration and setup of a tool probe

Transcription

1 Calibration and setup of a tool probe Fundamentals Tool-setting is the process of determining geometric information length, radius and / or diameter of a cutting tool using a tool-setting device. Some tool-setting technologies are also capable of determining information such as radial and linear profile and cutting edge condition. Broken tool detection can be performed by tool-setting systems and dedicated broken tool detection devices. Both tool-setting and broken tool detection enable unmanned operation of machine tools. The benefits of tool-setting Determining geometric information and the current condition of a cutting tool can help improve the manufacturing process including checking that the correct tool for the scheduled machining program has been loaded, correcting for tool wear, and automation of tool offset updating. Benefits of tool-setting n Improves accuracy n Reduces scrap n Reduces the level of operator intervention n Reduces cost n Broken tool detection Benefits of broken tool detection n Saves cycle time n Reduces re-work n Reduces scrap n Reduces cost NOTE Please observe the information provided by the manufacturers of electronic probes and / or the machine tool builder s instructions regarding the following points: n Electrical connection n Mechanical calibration of the probe n If a workpiece probe is used, both the direction of deflection and transmission of switching signal to the machine column (radio, infrared light or cable) must be taken into account. In some versions, transmission is only possible in particular spindle positions or in particular ranges. usa.siemens.com/cnc4you

2 General information Measuring cycles are general sub-routines designed to solve specific measurement tasks. They can be adapted to specific problems via parameter settings. When taking general measurements, a distinction is made between: n Workpiece measurement n Tool measurement Measuring can be performed in: n JOG mode with the use of semi-automated measuring functions for tool measuring by the machine tool operator n AUTO mode for in-process measuring with use of automated cycles in a part program Tool-setting products are referred to as contact or non-contact, depending upon the technology they employ. The two technologies kinematic touch probe or optical (laser) based both use an interface to communicate with the machine tool control. Non-contact systems employ laser technology to capture tool geometric information. Capable of radial and linear profile checking as well as cutting edge condition monitoring. Contact systems employ the ability of the probe mechanism to reseat after triggering to within 1.00 µm is fundamental for repeatability and good metrology. From simple length and radius checking to broken tool detection, this technology is available in almost all contact tool-setters. Figure 1 Calibration of tool probe for positive and negative tool offsets The function Calibrate tool measuring probe n Calculates the current distance (switching points) between the machine zero and the tool probe (calibration relative to machine) using a calibration tool. n Automatically writes them to a data storage area as trigger values. The tool probe has typically the shape of a cube or a cylindrical disk, and is mounted in the machining space of the machine (usually on the machine table) and must be aligned with the machining axes (machine axes). All necessary data of the tool probe (form, dimensions, etc.) are entered in the intended machine data for measuring in JOG. See General machine data for the tool probe setup found on page 9 for setting tool probe data parameters. The function Calibrate TL probe is only available if the general setting data $SNS_J_MEA_FUNCTION_MASK_TOOL is set. 2

3 Step 1: Calibration tool To calibrate the probe first a standard must be purchased or created. 1. Certified tool for precise calibration Figure 2 2. Calibration tool measured on pre-setting device Pre-setting device Figure 3 Determine length, diameter and concentricity Calibration tool Positive or negative tool offsets? Figure 4 (left) Positive tool offsets Figure 5 (right) Negative tool offsets 3

4 Positive tool offsets The offset represents the length of the tool measured as a distance from gauge line of the spindle (typically spindle nose) to the tip of the tool. The longer the tool, the larger your tool length offset will be. In such cases, the Z work offset will represent the distance between the same gage line to the top of the part. Positive tool offsets can be measured offline on a pre-setter and then tools can be quickly loaded into the machine without the need to tough off each tool on the machine individually. Negative tool offsets This represents the (negative) distance between the tool tip to the top of the machine bed. In such cases, the Z work offset will be the distance between the top of the gage line and the top of your part. Determining your tool offset depends upon your equipment and shop practices. Step 2: Define calibration tool in tool list The precise dimensions of the tool are known. Input the values from the tool pre-setting device into the tool list. Figure 6 Step 3: Determine position of tool probe Before you can start with the tool probe calibration cycle, you have to determine the approximate position in the machine coordinate system (MCS). In order to do so, change the calibration tool into the spindle, and traverse in JOG mode approximately into center, above the tool probe stylist. Figure 7 4

5 Write down the positional values in the MCS of the machine position display for the X- and Y-axis. Figure 8 Tool probes have their own data fields in the general setting data: For machine-related measurement/calibration: SD $SNS_MEA_TP_TRIG_MINUS_DIR_AX1 SD $SNS_MEA_TP_TRIG_PLUS_DIR_AX1 SD $SNS_MEA_TP_TRIG_MINUS_DIR_AX2 SD $SNS_MEA_TP_TRIG_PLUS_DIR_AX2 SD $SNS_MEA_TP_TRIG_MINUS_DIR_AX3 The trigger point refers to the machine coordinate system (MCS). Prior to calibration, the approximate trigger point must be entered in the machine coordinate system. The exact value of this parameter is created by the operation Calibrate workpiece probe Approximate values must be entered here before calibration if cycles are used in automatic mode. The cycle will then recognize the position of the probe. Enter the determined positions into the relevant setting data for the tool probe. Trigger points of the measuring axis: 54626[0] $SNS_MEA_TP_TRIG_PLUS_DIR_AX [0] $SNS_MEA_TP_TRIG_PLUS_DIR_AX [0] $SNS_MEA_TP_TRIG_MINUS_DIR_AX3 Press following softkeys, to get to the general setting data: 5

7 Now choose whether you want to calibrate just the length, or the length and diameter. Figure 11 Choose the Length and Diameter calibration mode with the Select softkey. Start the calibration cycle with Cycle Start button. The calibration process is executed automatically with measuring feed rate. The distance between machine zero and tool probe position are being determined and stored in the general setting data. Figure 12 The switching points (trigger points) of each measuring axis in negative and positive direction for tool probe, are stored to the following setting data [0] $SNS_MEA_TP_TRIG_PLUS_DIR_AX mm 54625[0] $SNS_MEA_TP_TRIG_MINUS_DIR_AX mm 54627[0] $SNS_MEA_TP_TRIG_MINUS_DIR_AX mm 54628[0] $SNS_MEA_TP_TRIG_PLUS_DIR_AX mm 54629[0] $SNS_MEA_TP_TRIG_MINUS_DIR_AX mm 7

8 Step 5: Check tool probe calibration data Measure the calibration tool on the machine with the electronic tool probe and compare the measured values with the values from the tool pre-setter. Use the same measuring velocity for calibrating and measuring. Figure 13 Figure 14 8
