Manufacturing Engineering: How important is the software side of today’s CNC development?
Tiansu Jing: More and more manufacturers are seeing productivity as a crucial factor to their business success. In the meantime, business models are changing from the large quantities and few variants to small quantities with frequently changed variants. This change requires high flexibility during production. Keeping a good balance between productivity and flexibility is a challenge for all manufacturing companies. A single machine’s productivity is limited by its mechanical and electrical condition and it is not easy to significantly increase that productivity.
The CNC and the machine itself cannot help the flexibility very much. Software becomes the game-changer in today’s manufacturing. And to support this trend, CNCs are developed that are even more supportive to the software.
ME: How critical is it for manufacturers to fully embrace the current move toward digitization in the industry?
Jing: To avoid falling behind in technology trends, all manufacturers must start changing. Most manufacturers are looking for the best solutions for them to increase productivity. This research and testing need time. If manufacturers cannot fully embrace the move towards digitalization in the industry right now, they will fall behind and lose to competition in the future.
ME: What new software elements are available for machinists in the Sinumerik CNC lineup, with Siemens’ ShopMill, ShopTurn and newer apps like Manage MyMachines?
Jing: There is plenty of new software available now from Siemens to improve customer productivity. The innovations include not only hardware, but also software like Mindsphere, Sinumerik Edge, and Sinumerik Integrate. Together with automation-level innovations, such as the new and powerful 828D panel processing unit (PPU), these new digitalization products can significantly help Siemens’ customers increase their manufacturing productivity and production flexibility.
ME: How common is it for machinists to use shop-floor programming on today’s CNCs?
Jing: I would say it is becoming more common than ever before. It’s because workpieces are not as simple as they were previously. In some cases, it will consume lots of time in programming on the machine, which will decrease the machine’s overall productivity. In other cases, the workpieces are becoming more and more complicated; therefore, software is needed for programming and testing.
ME: How easy is it for new machinists to learn CNC programming on today’s controls?
Jing: Thanks to new software technology, there are many different tools to help a new machinist learn CNC programming. Programming and operating can be taught on a PC with our Sinutrain software, which is a perfect simulator of the Sinumerik control with the real CNC kernel in it. Machinists can also practice on a PC with Sinumerik Virtual NC Kernel (VNCK), which is software with the Sinumerik Operate system and real NC Kernel. Sinumerik VNCK can be integrated into a machine 3D model, which is controlled virtually by the VNCK. With this software, machinists can not only practice programming and test it, but also operate a machine and see how the workpiece is cut with the program.
ME: What kind of aptitude does it take to become a good CNC programmer on the shop floor?
Jing: With advancements in hardware and software technology, it’s not necessary to have any specific aptitude to become a very good CNC programmer. Anyone can easily learn programming and operating by working on the software using a PC instead of an expensive machine tool. If there is one mandatory aptitude, it should be the willingness to embrace new technology.
ME: What does the current manufacturing climate look like for software and automation developers?
Jing: Now is the best time for software and automation developers. More and more entities have realized the importance of software in the manufacturing industry, and more companies are investing in software to embrace digitalization. Take Siemens for example—we have invested more than $10 billion in automation and software acquisitions since 2007. We have spent $5 billion in R&D globally. From the market perspective, the industry is aware of the importance of digitalization to overall manufacturing productivity and flexibility improvement. More manufacturing companies are buying thanks to the value of the software and automation system, which together support digitalization.
Siemens AG, based in Berlin and Munich, Germany, has signed an agreement to acquire the Noise, Vibration, and Harshness (NVH) end-of-line quality testing business of Saab Medav Technologies GmbH, an Erlangen, Germany-based supplier of NVH solutions for industrial quality testing as well as signal processing, communications intelligence, and analysis for air, land, and naval applications.
Siemens said the deal will extend its Simcenter simulation and test offering with the addition of Saab Medav’s NVH business. Quality testing results from Saab Medav systems will provide valuable input to the product digital twin, supporting continuous product improvement and development, the company said. The NVH team and technology complement the Simcenter test portfolio, enabling customers to systematically improve overall product and manufacturing quality.
According to Siemens, Saab Medav’s NVH quality testing solutions have a strong track record and best practices in the domain of end-of-line quality testing of combustion engines, transmissions, electric motors, and motor-driven components and systems. The addition of the NVH business allows Siemens to complement its Simcenter portfolio of testing solutions used in research and development with an integrated solution set for end-of-line NVH quality testing in manufacturing.
With ever-increasing pressure on improving quality, the need for NVH type end-of-line testing for manufactured products such as electric motors, combustion engines, transmissions, axles, and turbochargers is rapidly increasing across the automotive and transportation industries. This is accelerated with the ascent of electric vehicles, which have a low general noise level and are lacking the masking effect from a loud combustion engine.
The NVH team will join the Siemens PLM Software business, based in Plano, Texas, and part of the Siemens Digital Factory Division. NVH technology will be incorporated into the Simcenter portfolio of simulation and testing solutions. The asset sale and purchase transaction is due for completion in the second calendar quarter of 2019. The parties have agreed not to disclose any details of the transaction.

Hexagon Manufacturing Intelligence, North Kingstown, R.I., a division of Hexagon AB, Stockholm, has released an update of its PC-DMIS measurement software that adds workflow, performance, and user-experience improvements. The latest update, PC-DMIS 2019 R1, is the first of two major releases scheduled for 2019, with continued service pack updates to ensure maximum platform reliability.
In PC-DMIS 2019 R1, Hexagon introduces the new GD&T Selection and Capture tool, which saves users time and effort and reduces input errors by automatically transferring GD&T data from 2D “blueprints” into the PC-DMIS measurement routine. The software accomplishes this by using optical character recognition (OCR) technology. Other new features include a new PC-DMIS Protect module for customers with stringent process controls and auditing standards, as Protect enables users to control access to measurement routines and track modifications to them (available as a paid option). Only users with permission can amend protected routines and the business can track and audit any changes.
Probe protection also has been improved with enhanced calibration collision avoidance capability. During the user’s regular measuring system calibration, a new layer of intelligence allows PC-DMIS to identify areas of possible collision and ensure collisions between the probe and any fixed surface are avoided. Likewise, PC-DMIS 2019 R1 automatically inserts safe moves needed to avoid collisions around complex parts directly into the measurement routine.
“We are very pleased to release this latest version of our metrology software PC-DMIS,” said Ken Woodbine, product line manager for metrology software at Hexagon Manufacturing Intelligence. “PC-DMIS 2019 R1 continues the trend towards optimizing each of the three primary metrology tasks of measurement creation, execution, and collaboration. The improvements in this version bring us ever closer to a perfect balance between user experience and capability.”
Other notable enhancements include single-click ability to measure the thickness of a transparent material and calculate and report a 2D thickness and gauge position; and improved customer service with responsive HTML Help, enabling assistance without having PC-DMIS installed and with embedded multimedia support. The PC-DMIS 2019 R1 update is available now for download.
