Edgecam 2018 R1 upgrades
Two new items of functionality in the Roughing Cycle deliver greater efficiency in all three machining environments.
“Detect Undercut Stock enhances the already powerful stock detection command by analyzing previously undetected areas of stock. This option helps to avoid air cutting, reducing machining time – in some cases by up to half,” says Edgecam Brand Manager John Buehler.
The Waveform Roughing Strategy now enables users to determine the radius size when using the helical approach option by simply entering maximum and minimum values, which will aid the tool’s entry into the component.
Automatic collision detection has been added to the Rough Turning Cycle. In previous versions of the software, it was necessary to manually apply profile extensions to avoid collisions. Buehler notes that, as users no longer have to do this themselves, time will be saved in initially creating the CAM instructions. “An additional benefit is that this new function can be used to produce safer toolpaths in Strategy Manager.”
Edgecam 2018 R1 provides support for Deep Hole Drilling – also known as Gun Drilling. The new strategy empowers the user to control entry, exit and intermediate drilling conditions. “This will be particularly important where specialized Gun Drilling tools are used, and the process requires absolutely precise NC code.”
The Profiling cycle used in both milling and turning now has two new items of functionality. A Spring Cuts field has been added to the Multi Passes tab, which means that tool deflection can be removed where necessary by adding extra neutral passes, known as Spring Passes. This will be used typically when machining hard materials, as repeating the profile pass can result in improved accuracy and surface finish.
The Adjust Feedrate on Arc command improves cycle-time calculation. In previous editions of Edgecam, the postprocessor adjusted circular interpolation feedrates, which gave correct NC output, but not the best cycle-time calculation.
Support for JT Open files is incorporated for the first time. This is a lightweight 3D model format developed by Siemens PLM Software. “As this file format is expected to become increasingly popular, more and more Edgecam users will benefit with the files now being supported in the Solid Machinist Max license. There’s also support for AutoCad 2018 DWG/DXF files.”
An Editing Manual Milling function provides for editing a manually-created milling feature instead of having to recreate an entire feature when extra edges are required. This is expected to give considerable time savings to Solid Machinist users.
First released in Edgecam 2017 R2, the Edgecam Inspection module has been significantly enhanced, which Buehler says brings many new features to the software. “Considerable progress has been made with the postprocessor development and NC output, through new Code Wizard options. This includes support for Fanuc macros.
“Users now have full control when editing an Inspection feature, including a calibration technique. They can also determine both feature and properties characteristics.”
The Move Point function within the Inspection module has two further options: ‘Fixed Axis,’ and ‘Fixed On Surface,’ providing the ability to align a measurement point along a fixed axis or a solid face. The Plane Feature command enables users to choose to evaluate flatness on more than four probe touches.
Edgecam 2018 R1 continues cycle dialogs with pictures and context-sensitive help by updating the B-Axis Contouring Cycle, as well as the 3- and 5- Axis cycles. This not only assists experienced users in easily interpreting an infrequently used command, but also helps less familiar users to rapidly understand fundamental functionality.
The Pass Boundary To Cycles function, found in the Feature Properties window, allows an improved toolpath to be generated when the user engages Current Stock and picks a solid feature. Rather than using the stock limits, which can sometimes lead to unwanted passes, the toolpath is now clipped back to the feature’s natural boundary, which is particularly useful when creating automatic toolpaths in Strategy Manager.
Several user-experience enhancements include improved visibility and consistency of the Datum Workplane marker, useful when working with multiple component parts, on tombstones, and multi-face machining.
Additional functionality has been added to the B-Axis Contouring Cycle, which was introduced in the 2017 R2 edition. “Maximum Angular Increment will improve the surface finish by refining the NC output while machining complex turned profiles,” Buehler concludes.
