In profiling control of a contact type probe in which a contact point is moved along a surface of an object to be measured, while being in contact with the object by a constant measurement force F, a contact determination level is provided for detecting a predetermined force smaller than a target measurement force is applied to the contact point, contact determination is performed at the time when force applied to the contact point reaches the contact determination level during approach, and the contact point is shifted from position control to force control for bringing the contact point into contact with the object by the target measurement force. Thereby contact trace is prevented from occurring on the object to be measured without reducing approach speed as much as possible and lowering measurement efficiency. In this case, a command value of the force control may be interpolated and gradually increased from the contact determination level to the target measurement force, and thus impact increase and over-shoot can be prevented from causing due to high-response.

A surface texture measuring instrument includes a contact piece to be in contact with an object, a sensor driving mechanism that moves the contact piece along the surface of the object, a controller that controls the sensor mechanism, and a force sensor that detects a measuring force exerted on the contact piece when the contact piece is brought into contact with the object. The controller includes a target value output that outputs a target value of the measuring force, a feedback controller that performs feedback control of the sensor driving mechanism based on a deviation between the measuring force and the target value, and a feedback compensator provided on the feedback controller. The feedback compensator performs feedback compensation in accordance with the measuring force.

A gage inspecting apparatus includes a jog dial 56A for controlling an amount of displacement of a measuring spindle 22 at a time when the position of the measuring spindle 22 is finely adjusted, and a shuttle ring 56B for controlling the driving direction and driving speed of the measuring spindle 22 at a time when the position of the measuring spindle 22 is roughly adjusted. The relationship between the amount of rotation of the jog dial 56A and the amount of displacement of the measuring spindle 22 can be set in correspondence with a scale interval of the gage.
