The present invention provides a CNC-parameter generating method in an isometric projection environment for the control and processing of tubes by at least one CNC-tube bending machine at least comprising: i) to generate a first vector on a touch screen; ii) to carry out a verification step by a microprocessor, iii) to assign the first vector to one of the directions, NORTH, UP, WEST, SOUTH, DOWN and EAST; iv) to generate further vectors by tapping once on the touch screen; v) to input dimensional values for the vectors on the touch screen, and to transfer dimensional values from the microprocessor device to one or more computers. It is also provided a parameter generating system in an isometric projection environment for the control and processing of tubes by at least one CNC-tube bending machine.

A topology database generates topology data of a plurality of parts. The topology database acquires processing information including a tool name of a use tool and a processing order from a bending processing program of each part, and stores the processing information in association with the topology data. A processing information acquisition unit searches for a similar part with the same topology data as topology data of a processing target part, and acquires the processing information of the similar part. A tool determination unit calculates a range of a tool length which is able to bend each bending line using a tool with a tool name included in the processing information and which does not interfere with the part, and determines the tool with the tool name and a tool length within a range of the tool length as the use tool.

A deformation processing support system acquires target shape data of a work having a reference line; acquires intermediate shape data from the work in an intermediate shape having a reference line marked thereon; and overlaps the two data on each other by aligning the reference lines relative to each other, to calculate a necessary deformation amount of the work based on a difference between the two data overlapped on each other. To align the reference lines with each other, first and second alignment axes with the same length calculated for the respective reference lines are superimposed on each other. Subsequently, the intermediate shape data is relatively rotated with respect to the target shape data around the first alignment axis.

The invention solves the problem of the construction of a lance of a cleaning kit for medium-voltage power devices. The lance is equipped with an external assembly (A) and an internal assembly (B) placed therein, wherein the external assembly (A) constitutes a head (1) with clamps (2) and (3) of connections, mounted in it from the front, and connected to a body (4). The body (4) is detachably connected to an extension (5), which at the opposite end is detachably connected to a dispensing nozzle (6).
