Renishaw’s proven HS20 laser encoder system has been upgraded and is now able to achieve a new maximum speed of 2 m/s for large machine tool applications. Previously the system, which can deliver an accuracy of ±1 µm/m for axis lengths up to 60 m, was limited to 1 m/s but through improvements to the electronic design it has been possible to double the speed performance.
The improved speed allows for the HS20 laser head to be designed into higher velocity applications which are becoming more common in today’s manufacturing industries. The aerospace industry is a key market for large machine tools which require long range but highly accurate encoder systems. With throughput being a key consideration in any machine tool purchase, the improved speed of the HS20 ensures that it will continue to be the preferred long range laser encoder of choice.
The HS20 long range laser system combines the ultimate accuracy of a laser interferometer with the robustness needed for machine tool applications. It offers real-time position feedback with sub-micron resolution through both analogue and digital quadrature.
Delcam has released the 2016 version of its PowerINSPECT inspection software, the world’s leading hardware-independent 3D inspection solution. The new release includes greatly enhanced options for section measurement, more comprehensive collision avoidance, improved point cloud inspection, the ability to add notes to reports, and improved user control of CNC surface inspection routines.
Section inspection has been improved with easier creation of sections, better visualisation and enhanced reporting. The enhanced options for section editing in PowerINSPECT 2016 include a slider that can be used to move the section through the part with real-time updating of the CAD view. A specific value for the section intersection can still be entered if required.
New graphics options help with visualisation and reporting. In the CAD view, the default option highlights the section cut and displays a semi-transparent representation of the material in the foreground, providing an accurate 3D visualisation of the section in place on the part. During section creation the shading is updated dynamically as the section moves through the model. Alternatively, the near side can be hidden completely, or the complete CAD model can be shown in a solid colour as before.
Once the desired section has been chosen, the inspection path can be generated automatically. The points generated can be edited if necessary. The section can also be viewed and reported as a 2D true view of the section profile that is currently selected.
As with other PowerINSPECT measurements, the results of the section inspection can be viewed as spot confetti, deviation lines or vector lines. The results can be displayed either on their own or as part of a larger inspection sequence.
Automatic collision detection was introduced in PowerINSPECT 2015, with probe paths adjusted automatically when a direct move between inspection features would result in a collision. A new collision-free mode extends this capability by automatically creating links between inspection features as necessary. If a potential collision is detected, the software automatically creates and calculates a new linking path that avoids the obstacle. Collision avoidance is recalculated when the order of the inspection sequences is adjusted in the sequence tree.
Intermediate paths can still be created or updated manually. This is required when the CAD model does not include complete information about the physical reality, for example if clamps or fixtures used to hold the part are not included in the CAD data.
PowerINSPECT 2016 has improved reporting with the ability to include additional user-defined information. New ‘Report Note’ items allow the user to insert additional observations, including text and pictures. As with all other items in the report, the notes can be shown, hidden and re-ordered within the report.
The formatting of labels has also been enhanced, particularly for GD&T items. New options have been added to the dialog for session settings to enable further control of the label display. Furthermore, the label sizes can be edited in the session settings and grid lines can be displayed for clearer reporting.
A number of enhancements have been added for inspections based on point clouds. Firstly, point clouds can be imported from DMT and STL triangle files. Scanning acquisition performance is improved and points can be saved from a point-cloud scan each time there is a pause during the scan. Several point-cloud items can also now be created in a single point-cloud session without having to leave the full-screen acquisition view.
CNC surface inspection has been improved, making it easier to produce consistent results across a batch of components. New surface inspection groups provide better user control of point naming, and the positioning, contents and formatting of report images. It is also possible to reference CNC surface inspection groups directly in RPS alignments.
Finally, there are significant usability improvements for the CAD File Manager. It is now possible to import one or more CAD files by dragging and dropping them into the main graphics window. The highlighting and visualisation of individual objects in CAD models is further improved, making it easier to identify named objects and levels.
Versatile cutter with unique torque key offers trouble-free milling. Available immediately, Sandvik Coromant offers a new end mill for small diameters. The CoroMill 390 with size 07 inserts is a versatile cutter that is ideal for shoulder milling, deep shoulder milling, edging, linear and helical ramping, plunge milling, slot milling and face milling. From roughing to finishing, it offers reliability, precision and productivity.
Suitable for all machine types, the CoroMill 390 with size 07 inserts is ideal for mixed production and can be used with different materials and applications. General engineering shops, as well as specialized business segments, such as automotive and oil and gas component manufacturers, will benefit from its universal capabilities.
Grades for the CoroMill 390 with size 07 inserts are available for all of materials. The new insert grade GC1130, produced with Zertivo technology, gives this cutter an extra dimension of security when milling steel. The smaller inserts deliver higher cutter-teeth density for superior productivity.
A unique feature of this tool is the torque key that is specifically designed for size 07 inserts. This key provides consistent clamping every time. It has built-in spring functionality that allows you to mount inserts with the correct clamping force for reliable and consistent tool life. Coolant-through technology is standard on the CoroMill 390 with size 07 inserts for additional heat and chip control.
Troy Stashi, milling product specialist for Sandvik Coromant, says, “The CoroMill 390 with size 07 inserts is the most versatile small diameter end mill on the market today. It’s beneficial for anyone who machines small features in any size component including medical, automotive, and oil and gas parts.”
