Nesting Software | 8 Best Practices to Gain Productivity

Does the nest meet all production requirements?

Does the nest meet all production requirements?

When sheet metal nesting every parameter, machine setting, order sequence, or part layout choice impacts nesting productivity – time & material.

There are countless sheet metal fabrication requirements to be considered when placing parts on a CNC punch, laser, plasma, waterjet or router.  The design, the fabrication requirements, and the order sequence can have a significant impact on the quality of the nest.  How well those requirements are respected when compiling a  nest is at the heart of an effective sheet metal nesting strategy.

Let’s look some of the real world demands that these requirements place on a programmer when nesting, and more significantly, the tools and techiques available improve your numbers today. Read more …

4 Secrets to Profiting with Nesting Software

4 Secrets to Profiting with CNC Nesting

4 Secrets to Profiting with CNC Nesting Programs

Why would a fabricator consider, let alone implement nesting program? What’s in it for the manager or the shop personnel to invest in a CNC nesting program? There’s got to be ways to profit from this investment, why else would someone go down this road.

Let’s be upfront. Changing or introducing new software into the work environment means, well, change.    And there are costs to making such a change.  Beyond the monetary investment there is the time and effort invested in the research and implementation.  So any sound reasoning would lead us to believe there must be a profit at the end of the process to make that experience worthwhile. There needs to be benefits for the whole team – managers and shop personnel – to justify not only the expense but the transition time and effort. Read more …

Nesting Software | 4 Best Practices When Kit Nesting

Optimation Assembly Manager Nesting Software

Some manufacturers – maybe you – build products out of component parts.  Those completed products are kits or assemblies or units, depending on the term you use.  Some parts are sheet or plate metal; some are not.  Some parts involve extensive post-fabrication work (bending, forming, painting); some not.  But the one thing all kit parts have in common is that they belong together.  Kits are designed as a unit and need to be programmed together, nested together, cut or punched together, assembled together, and ultimately delivered together, which creates a rather difficult production challenge.

How do you keep the assembly parts together in a cohesive unit, while reducing the programming time, managing the material yield, and not slowing down machine productivity?  There are sheet metal software best practices to help.  Often times one or two of these goals are sacrificed to achieve another goal in what is seen as a zero-sum game.

It doesn’t have to be that way.  There are tools and practices that can help achieve all of these goals in concert and without sacrificing one good for another.  Let’s look at some of the day-to-day challenges kits present and some solutions to the problems. Read more …

Pros & Cons of Single Part CNC Programming

Single Part Programming | Time vs Material

Single Part Programming | Time vs Material

We often hear from manufacturers that they are doing single part programming.  Some do it by design.  Some do it by default.  Either way it is a process that dramatically impacts how your fabrication operation works.  Therefore, it merits a discussion to better understand what it is and how it strongly influences throughput and material efficiency outcomes.

How CAM Software Adds Value to a Product

Improving Delivery Speed, Service with CAM Software

Adding Value with Service and Product Improvements from Optimation

Now that we’ve discussed initiating a Lean Manufacturing Project, we’ll turn to deconstructing the sometimes mysterious — often foreign — components of lean thinking as it relates to the CAD/CAM process.  With these tools you can leverage your own knowledge of your business to make improvements that will, in hindsight, seem obvious.

So, let’s get started.

What is Value?

The first concepts to tackle are “value” and the “value stream.”  Intuitively we know what value means for ourselves and our products.  We know we have value as a person, spouse, employee, committee member because we bring knowledge and talents to our relationships and roles.  And we know our products have value — equivalent to the purchase price — because our customers buy them for that price!  But what do the lean manufacturing experts mean by “value,” and how does it apply to CNC Nesting and the CAD/CAM world?  Read more …

Balancing Priorities

When nesting, most manufacturers see a clear trade off between material efficiency and throughput.  They feel they must choose one or the other goal.  Sacrifice one “good” for the other.

And depending on the nature of the manufacturing operation, there may be only one, clear, obvious choice.  If you’re cutting expensive material, i.e. stainless steel, it would be common sense to save every last percent of material because waste is expensive and the cost only nominally retrievable. However, if you’re in a quick-turn-around shop where delivery is measured in hours, not days or weeks, you may be willing waste material just to meet the delivery requirements.  If the customer is satisfied with your responsiveness and offers more business or is willing to pay more for the fast turn around, the monetary loss in waste can be overcome.

However, most manufacturers don’t live in such a black-and-white world where there is only one, clear objective.
