Abstract
Abstract Switching equipment for numerically controlled machine tools is provided with at least one controllable switch for initiating a measuring process and a switch control which closes the switch when a supply voltage appears on a connecting wire, for example on a power supply connecting wire of an electric pump for cooling water. Therefore it is possible to measure automatically without any additional program-steps of the central processing unit.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
100 words
Switching equipment for numerically controlled machine tools comprising at least one controllable switch for activating measuring equipment, a switch control connected to said at least one switch, said switch control having an input connected to a power supply connecting wire of a pump for providing cooling water, whereby said switch control closes said at least one switch when a supply voltage having a particular magnitude appears on said wire to initiate at least one of a measuring process and a measuring transfer, said at least one controllable switch being closed only for a predetermined time interval by said switch control.
Claim 2
Dependent Claim
100 words
Switching equipment for numerically controlled machine tools comprising at least one controllable switch for activating measuring equipment, a switch control connected to said at least one switch, said switch control having an input connected to a power supply connecting wire of a pump for providing cooling water, whereby said switch control closes said at least one switch when a supply voltage having a particular magnitude appears on said wire to initiate at least one of a measuring process and a measuring transfer, said at least one controllable switch being closed only for a predetermined time interval by said switch control.
Claim 3
Dependent Claim
21 words
The switching equipment as defined in claim 1 further comprising several controllable switches which are simultaneously operable by said switch control.
Claim 4
Dependent Claim
24 words
The switching equipment as defined in claim 1 wherein the switch control has an input for alternating current and an input for direct current.
Claim 5
Dependent Claim
33 words
The switching equipment as defined in claim 1 wherein the switching equipment is located in a switch cabinet of a machine tool and is connected to the measuring equipment by a connector socket.
