Form compensation option from NUM

A form-compensation option has been launched by NUM for its Numroto tool-grinding software.

The option enables tool manufacturers to ‘close the loop’ between CNC tool grinding and measurement, further increasing process accuracy and consistency. NUM’s system inherently compensates for process variables, such as temperature fluctuations and grinding wheel wear, and is likely to prove popular with manufacturers of specialist precision tools, which demand tight production tolerances.
Machine shops seeking to maximise the accuracy of tools produced on CNC grinding machines generally use a CMM to obtain probed measurements of the machined part; using this information to influence the production process during subsequent machining operations. Until now, Numroto users processed CMM results with proprietary third-party compensation software running on an external computer, before feeding a suitably corrected target profile back to the CNC machine.
Designed in conjunction with several key Numroto end users, NUM’s form-compensation facility is a fully integrated part of the company’s form-cutter package, and completely dispenses with the need for any third-party software. The data exchange between the CMM and CNC machine can be handled by XML interface, or by export/import of the DXF file via a local area network (LAN).
The software employs filtering algorithms to create a smooth and precise compensation profile. Importantly, the orientation of the grinding wheel and the path speed from the original profile is always calculated so that only the position of the contact point on the cutting edge is compensated – and not the orientation of the grinding wheel. Performing the calculation in this way ensures that the surface quality of the tool is unaffected by the compensation. The form-compensation option is compatible with Numroto version 4.1.2 or later.

Global language of production

The VDMA and VDW are joining forces to promote the use and dissemination of OPC UA standards throughout the mechanical engineering sector under the ‘umati’ label.

“Cross-industry and cross-technology marketing will take our customers a significant step forward,” says Dr Wilfried Schäfer, executive director of the VDW (German Machine Tool Builders’ Association). “Manufacturing companies have not only machine tools but their own individual mix of equipment, robots and systems. If all these technologies can exist in a common ecosystem that is ideal for producing plug-and-play solutions, it will save end users a lot of time and money.”
Hartmut Rauen, deputy executive director of the VDMA (German Engineering Federation), adds: “Over 30 specialist groupings in more than 17 associations are working on technology-specific interfaces, known as the ‘Companion Specifications’. This high level of collaboration forms the basis of true, open interoperability between machines and software systems, from the shop floor to the cloud. Only the VDMA has the means to unite the necessary integrative forces from the wide range of production domains.”
The mechanical and plant engineering sector adopted OPC UA as the standard for data exchange from an early stage, largely because OPC UA provides a uniform framework for machine and system interoperability. Having adopted a bottom-up approach, it became clear how important it was to have uniform definitions for basic elements for a large part of the diverse range of products in mechanical and plant engineering. The simplest example is machine identification, including features such as manufacturer, serial number,
year of manufacture and machine type.
Here, various VDMA departments – such as Electrical Drive Engineering, Plastics and Rubber Machinery, Machine Vision, Metallurgy, Robotics and Machine Tools – are currently drawing up the ‘Basic Companion Specification OPC UA for Machinery’. The first version is scheduled for publication later this year.

Tool made using VISI helps COVID-19 plan

An injection moulding specialist helped a public school in Rutland to produce thousands of pieces of PPE for frontline workers during the early days of the COVID-19 crisis.

While Oakham School was closed during lockdown, staff used 3D printers and laser cutters from the Design and Technology Department to begin making face shields. The department approached local company, Rutland Plastics, to help it boost productivity, which took the team from manufacturing just a handful, to 8000 a day.
Rutland Plastics’ technical manager Carl Martin says they were originally asked to 3D print a number of headbands for the shields, but decided it would be more cost effective to manufacture a mould tool using its VISI software package, from which the plastic product could be injection moulded.
“We received the initial design for the 3D printed product, and modified it in VISI to make it suitable for injection moulding,” he says. “Once that was completed and approved, we designed the tool in VISI using a Meusburger bolster with aluminium bolster plates.”
The design then went into the tool room and was milled on the company’s Mazak VCN 530C CNC machining centre, with tool paths created through VISI’s CAM functionality. From taking in the initial 3D design, through turning it into a mouldable product, and finalising the mould tool, took less than a week.
When the two-impression mould was set up on Rutland’s 80-tonne Engel moulding machine, both parts of the headband were formed from a medically-accredited polypropylene every 24 seconds during the production run of 25,000. To complete the full screen face masks, Oakham School arranged for the headbands to be attached to plastic visors, which were then distributed to front line NHS staff.

Manufacturing Holds Key to Recovery of Oil and Gas Markets, revealed at this week’s ADIPEC Energy Dialogue

Bounce back in China’s manufacturing sector points the way; other countries expected to follow as lockdown is lifted

Latest in series of on-line ADIPEC Energy Dialogues hears it could be late 2021 before oil and gas markets recover to 2019 volumes
OPEC+ supply constraints coming under pressure from US shale and indebted oil producers as prices strengthen; production cuts likely to be rolled over and extended

Abu Dhabi, UAE – XX June, 2020 – A revival in manufacturing across the world holds the key to the mid-term recovery of oil and gas markets, with consumer demand likely to lag as the energy industry begins to recover from the twin shock of the COVID-19 crisis and the resulting demand crash.

Participating in the latest online ADIPEC Energy Dialogue, Rachel Ziemba, an economic and political risk expert and Founder of Ziemba Insights, said the early signs from China, the first major economy to exit from the COVID-19 induced lockdown, are that manufacturing has bounced back more than consumption and that trend could be repeated in other countries.

“It is notable that the COVID crisis and the associated economic and energy crisis has really been the first to blow out the global consumer,” Ziemba said. “2008 was much more of a hit to the financial sector and manufacturing. This time it is the reverse. The big question is how quickly consumer demand will come back.”

Ziemba added it could be well into 2021 before oil and gas markets get to volumes approaching where the industry was at the end of 2019.

Looking at the trends likely to impact the recovery of oil markets in the mid-term, Ziemba said the OPEC Plus group of producers has had some success in tightening the market. But a question mark hangs over how long supply can be constrained.

“The challenge is that a few countries, those that are most economically strapped and not eligible for debt relief, are not complying in full and some have barely reduced production,” Ziemba said. “Despite pressure from the likes of Saudi Arabia and Russia, it is going to be very difficult for them to comply because these are countries that had big fiscal deficits when oil was $70 a barrel.

“The other challenge is that we are starting to see parts of the US shale industry starting to reverse shut ins. We are also seeing more rig activity after many weeks of decline. In a price range of mid-30s into a 40 range, there will be more entities that can make some money and the risk is that it puts even more pressure on OPEC Plus. So, I do think the most likely scenario is a rolling over and extension of the supply cuts.”

Access to credit, to support economic recovery, is an additional challenge for indebted oil producing countries, which are having to deal with multiple shocks at the same time, including sizable outbreaks of the COVID-19 coronavirus that may or may not be under control. Many of the oil producers that are in a tougher financial position than their rich peers are too wealthy to qualify for debt relief, Ziemba said, heightening social, political and economic risks which could further impact the oil and gas industry.

Elsewhere, as oil and gas companies seek for ways to recover, Ziemba said she expects to see some industry consolidation, particularly in the United States with more cash rich entities looking to go into smaller, more speculative areas that are lower cost. She also highlighted the possibility of further job cuts as companies become leaner and decide between boosting commercial reserves, or partnering with governments. Meanwhile, she added she expects to see more National Oil Company enter into partnerships, for example Middle East producers and Asian buyers, which enable greater creativity in payment terms and contracts.

The ADIPEC Energy Dialogue is a series of weekly online thought leadership events created by dmg events, organisers of the annual Abu Dhabi International Exhibition and Conference. Featuring key stakeholders and decision-makers in the oil and gas industry, the dialogues focus on how the industry is evolving and transforming in response to the rapidly changing energy market.

ADIPEC 2020 is projected to attract more than 155,000 energy professionals from 67 countries; including senior decision-makers and energy industry thought leaders, over 2,200 exhibiting companies and 23 national exhibiting pavilions as oil and gas companies convene to share views and best practices to address the long-term impact of the triple challenge of lower oil prices, weaker demand and over supply.

Held under the patronage of His Highness Sheikh Khalifa Bin Zayed Al Nahyan, President of the UAE; hosted by the Abu Dhabi National Oil Company (ADNOC); and supported by the UAE Ministry of Energy & Industry, the Abu Dhabi Chamber, and the Abu Dhabi Tourism and Culture Authority, ADIPEC is scheduled to take place from November 9 to 11, at the Abu Dhabi National Exhibition Centre (ADNEC).
