Profiles drilling automatic calculation: a further step towards the manual work and mistakes minimization

Introduction

Your technical department, or better your software for the automation of production, can generate a set of documentation needed in the production phase.

In particular, together with the DWG drawing of the complete unit, with the internal component positioned in the right place and the cutting lists for metal sheets and profiles, your production plant is used to get the DXF drawings of the metal sheets, ready for the punching or laser machine.

If you have good luck, and in particular if you are among the privileged manufacturers that own a complete solution for your unit production automation, you get these documentation and drawings automatically, as output of your software for production automation (if you would like to see an example of such a solution, please have a look at AHU Designer product description at the following link: https://www.altecsoftware.com/thermodynamic-software/ahu-designer/).

Otherwise, your technical department engineers need to work on the AHU selection information to produce the needed drawings. The metal sheets drawings, both for panels and for blank off plates, besides the real dimension of the flat sheet, report also the needed workings and holes.

When you get your metal sheets ready, during the mounting phase, still one time consuming and important activity is needed to be performed in a manual way: the drilling of both structure and omega (reinforcement) profiles. In general, the calculation of the needed holes position and dimension cannot be performed by the technical department: calculation of profiles drilling needs to keep in consideration a lot of variables and, in any case, if you try to perform it manually, the possibility of mistake occurrence is quite high.

As alternative, you can ask your software to do the job for you.

The automatic calculation of profiles drilling

Your unit design and production automation solution should contains all the information regarding panels, internal metal sheets, profile mounting positions. Of course, this is possible only if the solution has been developed based on your real and specific requirements, and if the solution contains your own specific construction rules for your unit. This means that the output of the software can be sent directly to the production plant, without manual intervention on it (if you would like to know more about the importance of rules usage in AHU design software, please have a look at the following article on our blog: https://www.altecsoftware.com/2015/07/08/the-rules-of-thumb-to-get-full-flexibility-from-your-ahu-design-solution/).

The output generated by the software in an automatic way can includes the following:

  • holes position calculation of both structure and omega profiles with correspondence on mounting holes on panels
  • generation of command files for the integration with the profiles cutting machine
  • review of profiles cutting list, with the unique identification of profiles based on the holes on each of them (two profiles can be different also regarding the number and position of holes on it, not only about their material, size and length)
  • revision of manpower time for profiles
  • calculation of profiles drilling in correspondence of internal metal sheets mounting holes

This results can definitively benefit your company in terms of reduction of manual work and reduction of mistakes.

In the following pictures you can see some sample results of such calculation.

The “Rules of thumb” to get full flexibility from your AHU design solution

The title is, of course, a paradox (and I’m sure you realized it).

In  this article I’d like to speak about real and well-defined rules (the opposite of “rules of thumb” mentioned in the headline) to help AHU manufacturers to afford the issue linked to flexibility demands.

Flexibility in AHU design

As a modern AHU manufacturer, I’m sure you dealt with the following (or similar) issue many times.

You customer has space constraint: this means that your AHU must fit a reduced and well defined room. In many cases, your standard units catalogue doesn’t help at all: you need to design a bespoke AHU.

This means that if in your standard unit catalogue you have sizeN and sizeM models (for which you have predefined the frontal size, all the drawings needed for the production and for which you know very well the costs), in the specific case you need to design a new unit, with a new “sizeY” that is in the range “sizeN- sizeM”.

I’m pretty sure that, thank you to your experience, you managed to cope with this situation in different ways. For example, your technical department engineers can use the 3D solid model (if any) of a predefined unit and “stretch” it to get the needed dimensions. They can also take the existing 2D CAD drawings and adapt them to the new constraint and generate the documentation needed in the manufacturing phase.

Whatever is the workaround solution you adopt, some important drawbacks can be identified; among the others, I’d like to underline the following:

  • lack of cost control: most likely, you can say that the cost of new unit sizeY of our example will be between the cost of sizeN and cost sizeM similar unit, but you can’t be more accurate than this;
  • lack of time control: the process is slow, because you need to do it manually.

As alternative, you can ask you AHU design software to do the job for you.

Paving the way to automation in AHU manufacturing

ENGINEERING COMPANIES NEW  CHALLENGE: SHOWING THE BEST WAY

 

Mechanical industry, nowadays, asks a challenging requirement to engineering  companies that aim to be their partner: providing a full  set of professional services  and solutions to manufacturers, targeting their changing and day-by-day demanding  needs. By integrating the leading edge design approach with traditional engineering  principles, a skilled and modern engineering company must provide  clients with a “First to Market Time” innovative approach, appealing product designs on time and on budget. 

These results can be reached by harmonizing creative and innovative thinking, well consolidated experience and knowledge from  science and theory, to support customers from the initial idea to finished product (“concept to production” approach). To say it a different way, an engineering company should provide customized / individual consulting services for new ideas and cost reduction and product improvements for manufacturers existing portfolio.

Years of experience in dealing with product engineering place the engineering company’s expertise well beyond just mechanical engineering and industrial design activities. By recognizing different situations and specific goals of each individual client, they can make necessary adjustments to the design and production processes and related activities. The ability to anticipate possible outcomes based on past experience and unique view of different realities empower the engineering company to select the best product development path and recommend right and safe technical decisions in order to maximize the results while minimizing costs.

AHU manufacturing automation: few things a software house won’t tell you

SEGRETO

 

As AHU manufacturer, you have your own very specific an peculiar needs: in Altec, we realized it thanks to our more than twenty-years’  experience in strict contact with the HVAC market and with AHU producers.

But as a manufacturing company, you share also common needs with the manufacturing marketing in general: for example, you need to make  enough product at acceptable quality levels in order to reduce scrap product and keep volume fulfilment high.

Or, better, this happened in the past: today this is not enough. In the recent years, most likely you faced a more strict issue.

 

 

Things started to change in 2000 in manufacturing industry. Due to a pronounced decline in product demand and a rise in offshore  manufacturing competition, manufacturers expanded their methods and practices to include making the right products, at the right time, at the  right cost.

Doing this “right stuff” requires companies to provide agile response to real-time customer order updates and small order lots, continuous supply-chain coordination, and never-ending cost reductions in manufacturing processes, all the while complying with, and proving compliance to, governmental health, financial, and environmental regulations.

These post-2000 competition-inhibiting constraints are real, critical survival matters for companies that face stiff competition from low-cost manufacturing centers.
