General Basics General information Measuring cycles are general subroutines 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 ● tool measurements and ● workpiece measurements. Workpiece measurements In workpiece measurement, a measuring probe is moved up to the clamped workpiece in the same way as a tool and the measured values are acquired.
Page 14 General 1.1 Basics Tool measurements In tool measurement, the selected tool is moved up to the probe and the measured values are acquired. The probe is either in a fixed in position or is swung into the working area with a mechanism.

Page 17: Reference Points On The Machine And Workpiece
General 1.4 Reference points on the machine and workpiece Reference points on the machine and workpiece General information Depending on the measuring task, measured values may be required in the machine coordinate system or in the workpiece coordinate system. e.g.: It may be easier to ascertain the tool length in the machine coordinate system. Workpiece dimensions are measured in the workpiece coordinate system.
Page 18 General 1.4 Reference points on the machine and workpiece SINUMERIK controls use numerous frames: various basic frames, system frames, settable frames (e.g. G54), programmable frames: They interact in a frame chain to produce the overall frame and the workpiece coordinate system. Measuring cycles do not support any frames with an active scale factor.

If there is no machine axis Y, milling can be implemented with the following kinematic transformations. ● TRANSMIT ● TRACYL In principle, measuring cycles support kinematic transformations. This is stated more clearly in the individual cycles, measuring variants.
Page 22: Probes That Can Be Used
General 1.6 Probes that can be used Probes that can be used General information To measure tool and workpiece dimensions, a touch-trigger probe is required that provides a signal change (edge) when deflected. The probe must operate virtually bounce-free. Different types of probe are offered by different manufacturers. Probes are distinguished according to the number of measuring directions.
Page 23 General 1.6 Probes that can be used NOTICE • The measurement takes longer with mono probes since the spindle must be positioned in the cycle several times by means of SPOS. • In workpiece measurement, a bidirectional probe is treated like a mono probe. •...

Page 30 General 1.7 Probe, calibration body, calibration tool Calibration, gauging block A probe must be calibrated before it can be used. Calibration involves precisely determining the triggering points (switching points) of the tool probe and entering them in special data fields. Calibration is performed with a calibration tool.
Page 31: Measurement Principle
General 1.8 Measurement principle Measurement principle on-the-fly measurement The principle of "on-the-fly" measurement is implemented in the SINUMERIK control. The probe signal is processed directly on the NC so that the delay when acquiring measured values is minimal. This permits a higher measuring speed for the prescribed measuring precision and time needed for measuring is reduced.
Page 32 General 1.8 Measurement principle Measurement operation The procedure is described using the workpiece measurement. The procedure is the same for tool measurement. In this case, however, the tool is moved and the probe is fixed. Depending on its design, the actual movements of a machine may be different anyway. Workpiece measurement is described as follows: The workpiece is stationary and the probe moves.
Page 33 General 1.8 Measurement principle Measuring velocity The measuring velocity is dependent on the measurement path _FA and its default setting is 150 mm/min if _FA=1; if FA>1: 300 mm/min. Cycles parameter _VMS is then =0. Other measuring velocities can be set by the user to a value of >0 in _VMS (see Chapter 2). The maximum permissible measuring velocity is derived from: ●...
Page 34 General 1.8 Measurement principle Calculation of the deceleration path The deceleration path to be considered is calculated as follows: Δ Δ Δ Deceleration path in mm Measuring velocity in m/s Delay signal in s Deceleration in m/s Δs Following error in mm Δs = v / Kv v here in m/min...
Page 35 General 1.8 Measurement principle Measuring accuracy A delay occurs between detection of the switching signal from the probe and transfer of the measured value to the control. This is caused by signal transmission from the probe and the hardware of the control. In this time a path is traversed that falsifies the measured value. This influence can be minimized by reducing the measuring speed.
Page 36: Measuring Strategy For Measuring Workpieces With Tool Offset
General 1.9 Measuring strategy for measuring workpieces with tool offset Measuring strategy for measuring workpieces with tool offset The actual workpiece dimensions must be measured exactly and compared with the setpoint values to be able to determine and compensate the actual dimensional deviations on the workpiece.
Page 37 General 1.9 Measuring strategy for measuring workpieces with tool offset Computational characteristic of the mean value with different weightings k ● The greater the value of k, the slower the formula will respond when major deviations occur in computation or counter compensation. At the same time, however, accidental scatter will be reduced as k increases.

Page 39: Parameters For Checking The Measurement Result And Offset
General 1.10 Parameters for checking the measurement result and offset 1.10 Parameters for checking the measurement result and offset For constant deviations not subject to a trend, the dimensional deviation measured can be compensated by an empirical value in certain measuring variants. For other compensations resulting from dimensional deviations, symmetrical tolerance bands are assigned to the set dimension which result in different responses.
Page 40 General 1.10 Parameters for checking the measurement result and offset Dimensional difference check _TDIF _TDIF is active only for workpiece measurement with automatic tool offset and for tool measurement. This limit has no effect on generation of the compensation value either. When it is reached, the tool is probably worn and needs to be replaced.
Page 41 General 1.10 Parameters for checking the measurement result and offset Weighting factor for mean value calculation _k _K is active only workpiece measurement with automatic tool offset. The weighting factor can be used to give a different weighting for each measurement. A new measurement result thus has only a limited effect on the new tool offset as a function of _K.

Page 469: Glossary
Glossary Actual/set difference Difference between measured and expected value. Asynchronous subroutine Part program that can be started asynchronously to (independently of) the current program status using an interrupt signal (e.g., "Rapid NC input" signal). Blank measurement The blank measurement ascertains the position, deviation, and zero offset of the workpiece in the result of a ->...
Page 470 Glossary Delete distance-to-go If a measuring point is to be approached, a traverse command is transmitted to the position control loop and the probe is moved towards the measuring point. A point behind the expected measuring point is defined as setpoint position. As soon as the probe makes contact, the actual axis value at the time the switching position is reached is measured and the drive is stopped.
Page 471 Glossary Measurement result display Measurement result displays can be shown automatically during measuring cycle runtime. Activation of this function depends on the settings in the measuring cycle data. Measuring a workpiece at an angle A measurement variant used to measure a drill-hole, shaft, groove, or web at random angles.
Page 472 Glossary Mono probe A mono(directional) probe is a probe that can only deflect in one direction. It can only be used for workpiece measurement on milling machines and machining centers with slight limitations. Multi probe A multi(directional) probe is one that can deflect in three dimensions. Multiple measurement at the same location Parameter _NMSP can be used to determine the number of measurements at the same location.
Page 473 Glossary Probes are therefore classified in three groups according to the number of directions in which they can be deflected. ● Multidirectional ● Bidirectional ● Monodirectional (mono probe) Reference groove A groove located in the working area (permanent feature of the machine) whose precise position is known and that can be used to calibrate workpiece probes.
Page 474 Glossary Tool number The parameter _TNUM contains the tool number of the tool to be automatically offset after workpiece measurement. Trigger point The trigger points of the probe are ascertained during calibration and stored in block GUD6 for the axis direction. Variable measuring speed The measuring velocity can be freely selected by means of _VMS.
