Calculate the Expected Measuring Uncertainty for Machining Accuracy over Large Measuring Lengths
With its specification of the resulting length error after multipoint linear error compensation, the LIDA 400 provides the machine tool builder with an important index. It allows him to prepare a good assessment of the measuring uncertainty to be expected, and at the same time indicates the high accuracy of the LIDA 400 series.
Semiclosed vs Closed Loop Accuracy on Machine Tools
A decisive factor for the productivity of a machine tool, besides accuracy (can I use this equipment to manufacture this part in a reliable process), is the availability of the equipment. High productivity with consistently high part quality is most easily achieved with linear or angle encoders. Today, their application is considered standard, not only on universal machines, but also on production machines.
Reduce Setup Time, Increase Machine Use Time, and Improve Dimensional Accuracy
The use of touch probes reduces setup times, helps to increase machine usage time, and improves the dimensional accuracy of the finished workpieces. Their setup, measuring and monitoring functions can be performed manually or automatically. Touch probes are used primarily on milling machines and machining centers, and they are suitable for a large number of measuring tasks—both in the workshop and in series production.
Maintain Machine Accuracy Under High Speed and Acceleration
The successful fulfillment of manufacturing orders requires machine tools with high thermal stability. Machine accuracy must be maintained even under strongly varying load conditions. As a consequence, feed axes must achieve the required accuracy over the complete traverse range even with strongly varying speeds and machining forces. Linear and angle encoders ensure high precision of the components to be manufactured even under strongly varying operating conditions of machine tools.
Machining accuracy of machine tools
Productivity and accuracy of machine tools are important competition aspects. Rapidly changing operating conditions for machine tools, however, make it difficult to increase productivity and accuracy. In the manufacture of parts, increasingly small batch sizes have to be produced economically, and yet accurately. In the aerospace industry, maximum cutting capacity is needed for the roughing processes, whereas the subsequent fi nishing processes must be executed with maximum precision. For milling high-quality molds, high material removal rates are required during roughing and excellent surface quality must be obtained after fi nishing. At the same time, maximum contouring feed rates are necessary to realize the required minimum distances between the paths within acceptable machining times.
Uniformly Digital – The new hardware design for controls from HEIDENHAIN
For many years now, controls from HEIDENHAIN have been proving themselves in daily use in the workshop. Along with their suitability for the workshop, they are also characterized by the robust and reliable design of their hardware. At this year’s EMO trade show in Hanover, HEIDENHEIN will present its vision for the controls of tomorrow.
Fast, accurate contour milling with high surface definition
Manufacturing processes in mold and die making, as well as in aerospace technology, can be optimized through modern milling technologies like High Speed Cutting (HSC). Economic benefits, however, can only be achieved if both the machine tools and the control can handle higher traverse speeds than those used in conventional machining.
Accuracy of feed axes
Every year’s new machine tools have been showing improvements in effi ciency and power. Increasing feed rates and acceleration values have reduced machining times. At the same time, increasing accuracy has permitted ever-closer tolerances. On the one hand, these developments enable the machining of increasingly critical parts; on the other hand they simplify the manufacture of complex assemblies. Selective manual assembly and bench work can often be reduced. Also, higher accuracy of parts normally results in improved function of component assemblies. Dimensional accuracy in motor transmissions, for example, has increased service life and reduced noise emission
