Coordinate Measuring Machines (CMM) A coordinate measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, including mechanical, optical, laser, and white light. Depending on the machine, the probe position may be manually controlled by an operator or it may ...

A typical ultra-precision machine tool has five major sub-systems, including a mechanical structure, a spindle and drive system, a control system, a position-measurement and feedback system, and an in-process condition-monitoring and inspection system. These sub-systems critically determine the performance of the overall machine tool system.

The Fotonic Sensor™ is a non-contact instrument, which uses the fiber optics lever principle to perform displacement measurement, vibration analysis and surface-condition measurements. The Fotonic Sensor transmits a beam of light through a flexible fiber-optic probe, receives light reflected from a target surface, and converts this light into an electrical signal proportional to the distance ...

24 Comments. When using vibration data, especially in conjunction with modelling systems, the measured data is often needed as an acceleration, as a velocity and as a displacement. Sometimes different analysis groups require the measured signals in a different form. Clearly, it is impractical to measure all three at once even if we could.

Minimal thermal displacement. BTD-110 standard type spindle thermal displacement after 7 hours of continuous no-load operation in a temperature controlled room at 1000 min -1. X-axis direction : -1 μm (-0.04 μin) Y-axis direction : -14μm (-0.55 μin) Z-axis direction : 23μm (0.91 μin)

When performing a displacement measurement on black objects that reflect little light, the resolution becomes lower. This is because the amount of light is reduced at the receiving part and the signal received from the PSD becomes small. In such a case, mount the sensor as shown below in order to increase the amount of light received.

Additionally, the slideways of the ORC, which are located diagonally opposite each other, distort symmetrically in response to heat, keeping the center of the moving parts in the same position. Thanks to these measures against thermal displacement, the NTX2000 machine can offer high-precision machining.

The structure of the CNC machine is therefore designed to cope with the torsional forces and heavy duty cutting imposed on these machines. • CNC machines have more rigid construction when compared to the conventional machine. • The slide ways, guide and spindles of the CNC machine all look over proportioned when compared to the conventional ...

Physical sciences Mathematics and Physics. Displacement (geometry), is the difference the final and initial position of a point trajectory (for instance, the center of mass of a moving object).The actual path covered to reach the final position is irrelevant. Particle displacement, a measurement of distance of the movement of a particle in a medium as it transmits a wave (represented in ...

A CNC machine tool is an automated machine tool equipped with a program control system, which can make the machine tool move and process parts according to the programmed program. It integrates the latest technologies of machinery, automation, computer, measurement, microelectronics, etc., and uses a variety of sensors.

Features of slideways are as follows: 1. Accuracy of movement. Where a slide is to be displaced in a straight line this line must lie in two mutually perpendicular planes and there must be no 'crosswind', i.e. slide rotation (the principles of slide movements are analysed in the previous chapter). The general tolerance for straightness of machine tool slideways is 0–0.02 mm per 1000 mm ...
