2 2.1 SETUP This chapter describes the connection between the Display Unit and Measuring Unit. Unpacking and Acceptance Check Your LSM has been thoroughly inspected prior to shipment. The mechanical, electrical, and optical systems are guaranteed to operate properly. Unpack the package and check that the accessories, for the Display Unit or Measuring Unit, and signal cables, etc., are intact and not damaged. Contact Mitutoyo if anything is damaged or missing. 2.
Step 2: Attaching the ID unit 1. Loosen the two screws that secure the ID unit protection cover at the left on the real panel of the Display Unit and remove the cover by sliding it rightward. 2. Remove the dummy ID unit (amber) that has been mounted at the left of the “TRANSMITTER-1” connector on the rear panel of the Display Unit, then insert the ID unit (beige) that comes in the same package as the Measuring Unit.
2. SETUP IMPORTANT • If the dummy ID unit is still mounted, “ ” is displayed in the lower section of the display. If this is the case, turn off the power and replace the dummy ID unit with a proper ID unit. • If the ID unit has not been installed, an error display as shown at the right will appear in the upper section of the data display unit and the operation of this unit stops.
Terminal to which a grounding wire is connected. Ground the system using the provided grounding wire to avoid the effect of interference noise caused in the setup environment. Step 6: Checking the remote interlock connector Make sure that the short-circuiting pin is inserted into the “REMOTE INTERLOCK” connector on the rear panel of the Display Unit. If this short-circuiting pin is not inserted, laser emission is disabled, even if the power switch is on.
2. SETUP 2.3 Preliminary Checks The necessary connections should be completed by following the procedure described in the previous chapter. Simplified operation checks are described here. Step 1: Fully open the lens cap and shutter of the Measuring Unit. Fully open the lens caps and beam shutters of both the emission unit and reception unit to ready the laser beam for emission. The lens caps should be completely removed, and the shutters should be as shown in the diagram below.
• An error may be displayed at this stage, PROG however, the display at the right is not actually an error. Check the shutter of the Measuring Unit. For information about other errors that may result refer to Section 8.3, “Error Messages and Remedies”. 2.4 Initializing the LSM-6200 Display Unit After making sure that this unit is operating normally, initialize the Display Unit so it can recognize the Measuring Unit(s) to be used.
3 DISPLAYS AND KEY OPERATIONS This Display Unit is provided with many useful functions that can be customized according to the user's needs. This chapter describes these functions and key operations. 3.1 Outline of the Operation Modes 3.1.1 Measurement Principle In order for the user to understand the measurement principle of the LSM, the following paragraphs describe about the system block diagram, segments (measurement positions) and measurement interval (measurement time). 3.1.1.
The configuration of the system is shown in the above block diagram. A laser beam emitted from the laser oscillator is directed at the polygon mirror which rotates at high speed and is synchronized by clock pulses. The laser beam that is reflected by the polygon mirror is then collimated by the collimator lens towards the workpiece.
3. DISPLAYS AND KEY OPERATIONS 3.1.1.2 Setting the segment Set the objective portion of a workpiece to be measured. The highlighted and shaded portions created when the laser scans over the workpiece are controlled with each assigned number. In the basic setup a selection must be made from one of two cases: case where there are 1 to 4 highlighted and shaded sections, and case where there are 1 to 127 similar sections.
3.1.1.3 Measurement interval (measurement time) A measurement interval (measurement time) varies depending on the averaging method and the number of scans selected for the measurement data. There are two types of averaging method: the arithmetical average and the moving average. Select the one best suited for the user’s purpose.
3. DISPLAYS AND KEY OPERATIONS 3.1.2 Outline of the Operation Modes The LSM system has the following modes: 1: Basic setup mode, 2: Calibration mode, 3: Function setup mode, 4: Other setup mode, 5: Statistical result display mode, and 6: Measurement mode. Power ON Error check Power ON + SET SET 1 : Basic setup mode 6 : Measurement mode LOCK UNIT , LOCK UNIT SHIFT 4: Other setup mode DATA C RUN ENT SHIFT ( LOCK UNIT ) S.PR PRINT 5 : Statistical result display mode DATA C RUN , L.
3.1.2.1 Basic setup mode • This mode is used to customize the basic setup conditions, including the resolution, interface conditions, and available functions, according to the measurement requirements. For more information, refer to Section 4.1, “Basic Setup”. • To enter the basic setup mode turn on the power (turn the key switch clockwise from the “O” position to the “I” position) while holding down the SET key. Hold down the key for about 2 seconds to initiate the basic setup mode. 3.1.2.
3. DISPLAYS AND KEY OPERATIONS 3.1.2.6 Measurement mode This mode can be divided into the following operational states: 1) Measurement in the ready state • This is the measurement mode that is entered immediately after the power is turned on or if another measurement mode is aborted by pressing the C key (or by the RESET signal from the I/O interface or the “CL” command from the RS-232C/GP-IB interface).
5) Zero-run measurement • A measurement where the number of samples is set to “0” is called a “zero-run measurement”. • If the DATA C/RUN key (otherwise input RUN via the I/O interface or the “R” command via the RS-232C/GP-IB interface) is pressed, single-run measurement is started and repeated until the DATA C/RUN key is pressed again (or RUN is inputted via the I/O interface or the “STOP” command is inputted via the RS-232C/GP-IB interface).
3. DISPLAYS AND KEY OPERATIONS 3.2 Techniques and Terminology of Setup Functions 3.2.1 Program • A measurement will be automatically performed according to the registered (programmed) contents including the segment (feature to be measured) and GO/NG judgment criteria, etc., in advance. Registration is performed in the function setup mode. • This unit can hold a maximum 100 programs, which may include various settings suitable for up to hundred kinds of workpieces.
a) Single measurement One session of measurement will be performed according to the one specified program. The factory default setting is this single measurement. b) Simultaneous measurement • In one measurement session two specific programs are executed at one time as a pair. Combinations of program numbers to form these pairs are shown in the following table.
3. DISPLAYS AND KEY OPERATIONS 3.2.3 Function setup • Use this procedure to set up the conditions necessary for measurement.] For each program number register measurement conditions including the segment (part feature to be measured), measurement interval (measurement time), and GO/NG judgment criteria that are the best suited for the objective workpiece. • To enter the function setup mode press the SET key in the ready state. Each of the LIMIT , SHIFT → P.S V/P.
b) Plate (Sheet) • In the case of the width measurement of a transparent plate with no chamfer on edges, measurement may not be possible since acute-edge signals cannot be produced for such edges. Photo-electric signal Laser scan direction Transparent Workpiece Ideal edge signal Measurement is aborted because a sharp edge can not be determined. Binary voltage level (SHL) • For measuring a transparent plate-shaped workpiece Take the following precautions: 1. Incline the workpiece.
3. DISPLAYS AND KEY OPERATIONS 3. Changing the SHL • With the reference workpiece set up on the Measuring Unit, connect the oscilloscope to the [SCAN SIG.] terminal on the rear panel of the Display Unit and observe the signal. • SHL is the signal level for detecting a workpiece. Changing the level from the standard level of 50% to a level such as 75% will enable the measurement of a transparent sheet.
3.2.4.2 Ultra-fine wire measurement • In the special ultra-fine wire measuring region, a clear shade can not be obtained because a workpiece, with a finer diameter than that of the laser beam at the focal position, must be measured. Therefore, this wire diameter must be calculated according to a special algorithm. This requires the following restrictions to be taken into account in the basic setup where an ultra-fine wire measurement is designated.
3. DISPLAYS AND KEY OPERATIONS IMPORTANT 1. For measuring ultra fine wire with a diameter thinner than that of the laser beam, the SHL (signal level for detecting a workpiece) needs to be changed according to the workpiece size (external diameter). 2. Since the SHL is changed to the level most appropriate for the workpiece size, multiple workpieces or workpiece fixtures existing within the laser scanning range may disable the detection of a workpiece less than 0.05 mm in diameter.
3.2.5 Measurement of an odd-numbered-edge cutting tool • This function is used to measure the diameter or run-out of cutting tool (drill or end mills, etc.)that has an odd number (3, 5, ...) of cutting edges. • When the outside diameter, øD, of an odd-numbered-edge cutting tool is measured, the measurement errors as shown in the figure below will result if this LSM unit is set to Segment 2 (normal outside diameter measurement) for measurement.
3. DISPLAYS AND KEY OPERATIONS 3.2.6 Measurement with two Measuring Units (dual-unit measurement) • The LSM-500S series Measuring Unit allows measurement to be performed with two Measuring Units, if the optional dual-type add-on unit is provided. To use two Measuring Units they must be the same model. • About Measuring Unit 1 which is connected to “TRANSMITTER-1” side, and Measuring Unit 2 which is connected to “TRANSMITTER-2” side a) The W.P.
3.2.6.1 DW type • This setting is used if two workpieces are measured by two measuring units set in parallel. • On each of the Measuring Units 1 and 2 the measuring position can be selected from segments 1 to 7 (1 to 3 for measuring a transparent object) or edges 1 to 255.
3. DISPLAYS AND KEY OPERATIONS 3.2.6.2 DXY type • Used to perform X-Y (2-axis) measurement with two Measuring Units positioned perpendicular to each other. • For DXY-type measurement the objective portion of the workpiece to be measured should be selected through segment specification, not by edge specification. Select segments 1 to 3 for Measuring Unit 1, and select segments 5 to 7 for Measuring Unit 2.
3.2.6.3 DF type • Used to measure the diameter of a large workpiece using two Measuring Units facing each other, one stacked on top of the other, or positioned back to back. • For DF-type measurement the objective portion of the workpiece to be measured should be selected through segment specification, not by edge specification. Select segments 1 to 3 for Measuring Unit 1, and select segments 5 to 7 for Measuring Unit 2.

Reception lens θ e1 S Workpiece Photoelectric device (a) Measuring a small diameter workpiece Reception lens e2 θ S Workpiece (b) Measuring a large diameter workpiece If a large-sized workpiece is measured using the DF-type setup, combined calibration will ensure more accurate measurment. c) Combined preset While combined calibration is used to measure workpieces of various sizes, the combined preset is used to measure workpieces with a dimension close to the reference gauge.
3. DISPLAYS AND KEY OPERATIONS 3.2.8 Automatic measurement with an edge specification • If the edge specification is made, it is possible to automatically measure IC or connector leads with respect to their pitch (even intervals), outside diameter, or gap. This is suitable for inspecting the IC lead bend, etc. Outside diameter Gap Pitch Laser scanning direction • This function is only in effect if the necessary setups are made for edge specification in the basic setup.
3.2.9 GO/NG judgment • All the measured data are subject to GO/NG judgment. To enable, set the GO/NG judgment criteria in advance. • The following settings can be made in the basic setup. a) The method of tolerance judgment can be selected from (Lower limit value and upper limit value), multi-limit selection (7 limits) and (Target value and tolerance values: upper tolerance value and lower tolerance value).
3. DISPLAYS AND KEY OPERATIONS 3) If all limits from L1 to L6 are set for multi-limit selection Multi-limit selection output GO/NG judgment L1 -NG Measurement from L1 to L6 are set. Measurement < L1 L2 GO L1 ≤ Measurement < L2 L3 GO L2 ≤ Measurement < L3 L4 GO L3 ≤ Measurement < L4 L5 GO L4 ≤ Measurement < L5 L6 GO L5 ≤ Measurement < L6 L7 +NG L6 ≤ Measurement 4) If only L1 and L2 are set for multi-limit selection No.
3.2.10 Abnormal data elimination • The abnormal data elimination function eliminates measurements that are very different from those specified for the machined workpiece, from the measurement data (neither the measurement is displayed nor is data output performed). If, for example, the grindstone of a centerless grinder is controlled based on the measured data from the LSM, it is possible that a large measurement error may be created due to the coolant used with the workpiece.
3. DISPLAYS AND KEY OPERATIONS 3.2.11 Preset/Zero-set This function is used to measure the difference between the workpiece and the reference gage or to measure the workpiece that is larger than the measuring range of the LSM. a) Preset • In this system the operation of setting the reference gage dimension is called the preset operation. • This function is applied to measure the absolute dimension of a workpiece. b) Zero-set • Setting the reference gage dimension to “0.
3.2.13 Reference value • This function is used to output deviations (measured data - reference value) between the reference value and the actual measurements of a workpiece for the Analog I/O Interface. Before analog output, set the reference value and the scale value (gain). • Measured data is outputted as analog signals at a full scale of ±5V. Analog signal = (Measured data - reference value) x scale value (gain) • In the basic setup the following conditions can be set.
3. DISPLAYS AND KEY OPERATIONS 3.2.15 Automatic workpiece detection • Automatic workpiece detection is performed for continuous-run measurement, where measurement starts with no specified workpiece present (Err-0), then proceeds to automatic detection of the workpiece, followed by measurement repeated number of times. No specified workpiece present (Err-5) also refers to the workpiece outside the upper and lower detection limits.
Setting example: • Lower detection limit: L < (a +D) / 2 • Upper detection limit: H > Upper limit of the measuring range or 1.1 D (This setting may be omitted.) • Invalidation period : T > (c / V) ms • Number of measurements: N < (ᐉ - 2c) x 0.8 (safety factor) / measurement interval / V 2) Position detection method • This is used to automatically detect a workpiece that enters the measuring region in the laser scanning plane in the same direction of the scan.
3. DISPLAYS AND KEY OPERATIONS 3.2.16 Group judgment • While the tolerance judgment is applied to each measurement from a workpiece, this group judgment is applied to a group of the specified number of workpieces.
3.2.17 Recording the amount of light • The gap measurement may be unstable if not enough laser beam passes through the gaps. In the case shown in diagram (a) below, an adequate amount of light can be obtained as the laser passes through gap (g) above the workpiece, even if the gap (t) is small. However, in diagram (b) where gap (t) is small, measurement will be affected.
