6.3.2 Technological and coordinate measuring mechatronic machine company «LAPIK» As an example of the Russian technological machine-hexapod is a precision piece of equipment offered by JSC ’LAPIK» (Saratov). The company produces in a single structural basis of hexapods of two types: coordinate measuring machines (CMMs) modules and technology modules (TM) for machining. The combination of features of the machining center and CMM gives the possibility to: • precisely to «coordinate» new areas to the already finished surfaces; • adjust the motion path of the tool taking into account the deformation of the workpiece (this is especially important when handling long items high precision); • to approve and, if necessary, to Refine the product on one workstation. Technological modules are intended for processing shaped products with high precision by methods of milling, grinding, drilling, polishing, as well as to perform operations of engraving, boring, layout. The working area of hexapods varies from different models in the range: X axis – 500...3000 mm, Y axis – 400...1400 mm, Z axis – 350...750 mm. Maximum turning angle of the moving platform with respect to each of the axes is 45...60°, the speed of its motion is specified programmatically in the range of 0.01...160 mm/s. The production machines are equipped with mechatronic modules, such as «motor spindle» power from 1.5 to 7.5 kW with variable speed in the range 400...24000 rpm. CMM perform automatic measurement and control of dimensions of parts (including the easily deformable parts) of the design or technological bases. The accuracy of volumetric measurement for CMM-500 (the machine of standard version) is not greater than 3.8 µm for the measured size – L = 300 mm. In precision machinery a special performance this indicator reaches the value of 1.1 µm. Measurements are performed using a special head-probe, equipped with mechanical sensors or current touch. Contact force when the touch current does not exceed 0,0003 N that allows you to measure pliant and fine-grained details. The positioning error of the working body of technological machines of the type TM is 5.0 µm (movement distance 300 mm). жүктеу/скачать 11,25 Mb. Достарыңызбен бөлісу:
