Nesting Efficiency Figures – What Everybody Ought To Know

Here’s A Quick Way To Understand Sheet Metal Nesting Efficiency Numbers

Why Manufacturers Track Material Efficiency

Manufacturers track their material efficiency for a few reasons. They follow efficiency numbers as a means of keeping an eye on day-to-day costs.  They look at variances in their material efficiency numbers to see if any production changes (part mix, sheet size, trim allotment) have made a difference in efficiency.  Finally, manufacturers frequently look at material efficiency as one basis for evaluating the return on investment when sizing up different sheet metal nesting software or CAM packages.

How to Measure Material Efficiency

We  now turn to the task of measuring or calculating material efficiency.  Read more …

JIT Nesting Software Helps Respond to Change

We often hear from programmers and engineers  about the hours upon hours they spend librarying parts, creating programs, and optimizing tool paths.  Then they hope nothing changes in the schedule to disrupt their much-labored-over work.  And you know how the story ends.  Something happens – it always does – that throws the schedule into a tailspin, the nests are scrambled, the work starts over, and someone loses their lunch break just to keep the ball rolling.  Meanwhile that equipment is still waiting; waiting impatiently with its metaphorical metronome ticking – loudly.

The solution to this time-and-time-again proven problem is simple.  Just wait until the very last minute – seconds – before the laser, punch or other fabrication equipment has completed the current nest and the operator has unloaded it to create the next nest.  That very next nest would reflect precisely current demand – orders, order quantities, part revisions, and material inventory – and prevent the dreaded last minute scramble to accommodate any and all changes.

It’s possible to do this.  Really.   Allow me to introduce you to “Just-in-Time Nesting.” Read more …

How to Shop for Nesting Software

Sheet Metal Software Shopping Tools & Techniques

Sheet Metal Software Shopping Tools & Techniques

Whether you’re in the market now or think buying sheet metal software may be a project in the future, it’s helpful to have tools and techniques to make the process easier, more efficient and a productive use of your time.

Assuming you’re not a professional buyer or in the corporate product acquisition department, you may not be used to identifying, evaluating, requisitioning, budgeting, and purchasing sheet metal software.  It can be a daunting task for the uninitiated or the already busy.

Indeed, most manufacturing engineers, programmers, or even manufacturing management doesn’t concern themselves with the software acquisition process on a day-to-day basis.  Their focus is all about producing parts and products.  And suffice to say, there isn’t a lot of overlap in the steps and processes involved in purchasing software and producing a product.  So there is often a fairly large, on-the-job learning curve to be had for anyone endeavoring to research and purchase sheet metal software.

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 …

Estimating Material Yield and Machine Time

Introducing | Project Estimator by Optimation

I think it is fair to say that most – if not all – manufacturers are scoped-in pretty tightly on their costs these days. Competition – global and domestic – economic turns, and rising energy prices are forcing a heightened awareness of costs.

Any tools to help predict and evaluate costs using actionable data would be a welcome asset.

Wouldn’t it be great to know how much a part would cost before you produce it? Read more …
