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.

How to Evaluate Your Sheet Metal Nesting Process | Part 1 of 4

How to Evaluate the Nesting Process

Steps to Evaluate the Nesting Process

Most would agree that sheet metal nesting is process.  There are steps; some sequential, some parallel. The activities flow; sometimes well, sometimes not so well. Decisions are made, information is shared, and actions are taken.  The sum of which is a process.

Even though there is significant value to looking critically at the process, most manufacturers rarely review the it unless there is a mandate to begin a Lean Initiative, a major problem, or an alternative sheet metal software solution is under consideration, which is sometimes indicative of a major problem.   Why? Because the day to day management of the process is all consuming. Read more …

Does Mixing Shop Orders Make You Nervous?

Not Dynamic Nesting of Mixed Orders

Not Dynamic Nesting of Mixed Orders

Does the thought of mixing orders in a nest strike fear into your heart?  Or does it just feel better to keep your items separate, like food on a tray -  no mixing allowed.

This probably isn’t you, but maybe you’ve heard of others, who under penalty of death, will not mix orders when nesting.  It’s true.  We hear about it a lot.

Although I’m having a little fun with it here, some have very real concerns about mixing parts from different orders, jobs, customers on a single or series of nests.  And those concerns are probably based in real-world, nightmarish experiences.

Today, we’ll look at the challenges of mixing orders and some best practices and tools to address them.  Then we’ll consider why mixing orders would be beneficial when done right and with the right tools.  Finally, we’ll ask the questions you may be asking to determine if mixing sheet metal nesting orders is right for you.

CAD/CAM Information Management

Best Practices for CAD/CAM Information Management

Effective communication is the lifeline of most businesses.  It couldn’t be more important in manufacturing, or specifically, to the CAD/CAM process.  Where there is lack of communication or miscommunication between CAD and CAM there is waste.  And we know intuitively waste from poor communication is costly and even more costly to fix.

CAD/CAM information management is all about creating and tracking an order and/or the part geometry from sale through delivery.  Let’s look at some of the CAD/CAM information management challenges and categorize them by the impact they have on delivering value to the customer.  Read more …

Solving Production Problems with CAD/CAM

Solving Production Problems with CAD/CAM

Is the boss concerned about waste?  Are you asked to make cuts?  If so, you’re not alone.  Many manufacturers are belt-tightening.  However, the challenge most run into is finding waste beyond the obvious pile of scrap material.

The good news for searchers is that waste is everywhere.

Today, we’ll look at the CAD/CAM process in light of the lean manufacturing concept of “value stream.”  With this approach we’ll find lots of waste to root out and lots of unsung value in our processes. Read more …
