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 Outline of the Operation Modes 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 block diagram described in the previous page. 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 H.CAL Ready state , L.CAL 4: Other setup mode 2 : Calibration mode RUN ENT SHIFT ( LOCK UNIT ) C.
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 SET 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 “CL” command from the RS-232C interface).
5) Sample measurement • A measurement where the number of samples is set to “2~999” is called a “sample measurement”. • In practice this will take place as a single-run measurement or a continuous-run measurement. From the measured data the calculation items (mean, maximum value, minimum value, and range) that have been set for the sample measurement will be calculated and the resulting data will be automatically subject to GO/NG judgment.
3. DISPLAYS AND KEY OPERATIONS 3.2 Techniques and Terminology of Setup Functions 3.2.1 Program • A measurement will automatically be 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 of 10 programs, which may include various settings suitable for up to ten kinds of workpieces.
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.
3. DISPLAYS AND KEY OPERATIONS b) Plate (Sheet) • If the workpiece being measured is a transparent plate (sheet) with edges that are not chamfered or beveled, there may not be a sharp contrast in the amount of light at the transition from the highlighted portion to the shaded portion. As a result, the voltage generated by the incident light on the photo-electric element can not reach the threshold voltage level (SHL), and Segment 2 is determined to not exist (Err-0).
3. Change the SHL Change the standard SHL (50%) of the photo-electric signal generated. The SHL can be changed in a range between 50% and 90%. First place a reference workpiece in the measuring region and connect the oscilloscope probe to the SCAN SIG connector located on the rear panel of the Main Unit. Observe the signals. Set the SHL to the center of the waveform that corresponds to the shadow from the smaller edge.
3. DISPLAYS AND KEY OPERATIONS 3.2.6 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.
3.2.7 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). The judgment result with the multi-limit selection will be outputted via RS-232C interface.
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.
3.2.8 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 3.2.9 Offset/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) Offset • In this system the operation of setting the reference gage dimension is called the offset operation. • This function is applied to measure the absolute dimension of a workpiece. b) Zero-set • Setting the reference gage dimension to “0.
3.2.11 Reference value • In the basic setup the following conditions can be set. a) Whether the target value of GO/NG judgment is being copied to the reference value. If this is selected, the setup guidance for the reference value will not be displayed. b) It is also possible to set so that tolerance judgment can take place in the ready state.
3. DISPLAYS AND KEY OPERATIONS 3.2.13 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 < (L - 2c) x 0.8 (safety factor) / measurement interval 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 3.2.14 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.
3.2.15 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.
