Evaluating the Sheet Metal Nesting Process | Part 4 of 4

How to Evaluate the Nesting Process

Steps to Evaluate the Nesting Process

This post concludes our series on evaluating the nesting process.  We’ve established a foundation for a process review, reviewed the CAD to CAM process, and looked at the order entry side of the equation.  Now we’ll turn to the heart of the nesting process, the actual creation of nests and output of tool paths to the equipment.  This is often the make-or-break element in the process that determines efficiency (material and time), throughput and the overall effectiveness of the sheet metal fabrication process.

Again, we’ll follow our method of first describing the status quo, evaluating it critically, then looking for alternatives.

Automatic Nesting and Automated Nesting – Smart Shoppers Know the Difference

Automated Nesting v. Automatic Nesting

Automated Nesting v. Automatic Nesting

To the uninitiated manufacturing professional the two terms “automatic” and “automated” as they apply to nesting and nesting software can whiz by undifferentiated in a conversation.  That’s perfectly understandable because our everyday experiences afford us no reason to assume there is much difference between the two terms.

Ah, but it is in that distinction where an important mistake is made when it comes to looking at nesting processes and nesting software.  Read more …

How to Evaluate the Nesting Process

Steps to Evaluate the Nesting Process

In the last two blog posts we’ve first laid a foundation for evaluating a process, then applied that foundation to the CAD to CAM process or geometry acquisition and data cleaning and storage steps.  As you know the nesting process takes input from two areas – design and scheduling.  Now we’ll turn to the other side of the equation (parts + orders = nests), and evaluate the order entry and order communication process as it relates to nesting.

Every manufacturer has a capturing and communicating order information approach.  It can be a paper-based system with travelers and making use of the “sneaker-net” to transfer the information.  It can be an Excel spreadsheet with a list of customer orders and associated parts, or it can be a sophisticated MRP/ERP system which is updated in real time.  Regardless of the tools in place, there are fundamental process requirements that can be described, evaluated, and compared to alternatives.

Here we go. Read more …

How to Evaluate the Nesting Process

Steps to Evaluate the Nesting Process

In the last blog post we laid out an architecture by which we can critically evaluate a nesting process.  To review, our evaluation process starts with a clear and detailed description of the nesting process, they we ask “why” about each of those defined steps, finally we look for constructive alternatives. Our goals in sum are identifying challenges, means to improve the process, and overall opportunities for efficiencies.

Today we’ll apply our evaluation architecture or system to the processes we’re most familiar with in nesting – collection of part geometry and creation of the part program.

We start at the beginning of the nesting process for most manufacturers, which is creating, identifying, moving, cleaning, and all around getting the geometry from where it is to a place – literally and figuratively – where it can be manufactured.  Read more …
