stylus cone angle and tip radius

Motion of the stylus causes an unbalance of the bridge indicative of the extent of stylus motion.

A stylus holder (102) is biased into a kinematic rest location within the stylus module (12).

A stylus is mounted on the body.

The stylus (28) may be removed from engagement with the retaining member (16) in the course of a stylus changing operation, wherein a differently configured stylus is mounted upon the retaining member (16).

The feeler portion may include an indentation.

In the analysis circuit, a phase rotation device for the measuring feeler sets in phase rotation the analysis signal chains provided by the measuring feeler to simulate an alignment of the measuring feeler.

A feeler (5) is arranged between the rollers (3, 4).

the operation of releasing the props can be improved by the addition of a roof feeler

A directional dependence of a flexibility of the feeler (11) is determined and/or is known.

The invention relates to an intermediate element for arranging a tracer pin against the tracer pin carrier of a coordinate measuring machine, comprising a one-piece main body having a tracer-pin end and a machine end.

Said means for estimating the thickness of the frame comprise the tracer (19) for measuring the contour.

A calculating means (6) calculates an actual position of the tracer head (41).

When the tracer head (4) has made a round of the model (6), a reverse turning control is performed in the direction opposite to that in which the tracer head (4) has turned.

According to these speed command values (Vxs), the tracer head copies the model, preceding the tool.

In the original sensing arm, the light is reflected by the reflective plane and is propagated in the longitudinal direction of the sensing arm again and is detected by the photodetector.

The invention relates to a thread detector (F), especially for a thread sensor in a thread feeding device, comprising a detector foot (A) with an essentially flat rest (B) which can be brought into contact with a thread (Y).

A position detector using a magnetic bearing spindle with which both working and position detection can be made.

An optical detector, for recording the displacements of the feeler (28), comprises a light emitter (52), for generation of a defined light figure (64) and a light receiver (54, 56).

Each needle assembly compartment (3) includes at least one track (19) adapted to receive a follower pin (25) coupled to a needle assembly (4).

When the soldiers tried to arrest him, a follower drew a sword in his defense.

The part handler further has a surface follower upon which the sensor is mounted, thereby maintaining a constant distance between the sensor and the exterior surface of the cylindrical metal part.

The bend core (16) comprises a support bar (19), a contrasting ogive (20) and a possible bend-follower element (21) disposed articulated at the head of the contrasting ogive (20).

According to the invention, the global effort provided by the actuating means varies, continuously or in steps, over the reading according to the position (Z) of the follower along the first axis.

At least one electric switch (56) emitting a signal during the excursions of the probe (38) is added to the probe holder (34).

To achieve this, a lens (23) is attached to the probe extension (21) between the optical sensor (10) and the probe element (22).

In order for a probe (8) to be able to self-centre, said probe comprises four opposing paired measuring points and may be brought into contact with two measuring points on two opposing sides of the walls of the recess (2) in a serial manner.

The scanning head holds a scanning probe (28) for scanning the measurement object.

Said stylus (4) is exchangeably fastened on the probe head mechanism (34) via a stylus changing device (33).

A linear zone of the hall current, which lies around the change in polarity, is processed as the measurement of the deflection of the tracer pin (18).

The invention relates to a scanner head (10) for a co-ordinate measuring device, said head being equipped with a tracer pin (18) that is elastically suspended in a housing (12).

When the tracer pin (18) is deflected, the magnet (34) is displaced along its axis, defined by the north pole (N) and the south pole (N) of said magnet (34), laterally passing the hall element (36).
