In this blog, we will talk about ideas to help get the most out of your software by making in interact and enhance you production line productivitiy and maximize the speed of your machines.

There are many different scenarios that require different approaches.  The one key component should always be "Make what you sell and sell what you make".  This means, if your shop is geared for high end one of a kind items, you should not try to push through a job that has 1000 of a like item every day.  If your shop has fast heavy duty saws and point to points for high end repetitive production, a custom job of ones and twos is not the best job to process.  However, may larger shops are running dual lines, one Nesting and one Cell manufacturing that can handle both.  Here will will discuss some do's and dont's and what to look for.

We will also talk about ideas that can help your company specifically.  Having years of experience in the field, I have encountered many things that work, work well and just fail miserably.  The only stupid question here is the one not asked.

If you have some ideas you found work great in your shop, please feel free to share your success.

For those of you who follow the threads on the Advanced Frameless Library, just so you know, everything I build into this system is with years of experience on the shop floor and from having been in hundreds of shops around the country.  

The logic I try to follow is simple.  I like the product to produce as fast as possible through a production line, with the highest quality and take the least time to get out to the shop from the front office.  I even try to expedite in the field installation with some features to help installers get the job done faster.

If you really look hard at these options, you will see these goals addressed.  If you have never thought of using any of these features such as sex bolt holes or top mounting holes, I suggest you inquire on these blogs as we can point you in the right direction.  Give some of these items a try on a job or two, see how they work for you.  The best part, you can turn these things on and off at will.

A recent topic of discussion on the forums relates to labeling.  I would like to offer some insights that may surprise you.  Some of this information, shops spend thousands of dollars in consulting fees to learn, I know, I used to do it.  One mistake that is often made, is piecing together a automation line without looking at the “Process” from top to bottom before building it.  Many of the little things get overlooked in trying to achieve a low bottom line price, resulting in a headache that costs you money every day.  We will weed out some of these items in our discussions as they do not all apply to every shop.

There is no one size fits all approach with any process out there, its just not reality.  So, lets break down some do’s and don’ts.  There is one rule I like to get people to follow.  Make what you sell and sell what you make.  What that means, if you don’t have Face Frame equipment, don’t sell a job with face frame cabinets, it’s a losing deal.  If you have a huge Cell Manufacturing line, don’t bid in little tiny jobs with 20 or 30 cabinets.  You get the picture.

Many of the larger shops now deploy two lines, a Cell and a Nesting line, one for high output and one for the smaller custom jobs.   Now, the labeling issue, if you run high volume, you say, I don’t want labels for every part, don’t need them, and there is a good reason behind this, but that same idea does not do well on the Nesting line, does it?  So, what do we do?  

If speed is truly the issue, then optimization usually is set to a lower yield, for higher output.  To get one label for many parts, a touch screen labeling system is a good fit, where the operator can put one label on the first and last part in the stack as they need, as opposed to the saw automatically outputting a label for every part.  Many optimizer have controls to keep like parts together as much as possible to make this a more viable approach.

If you’re a medium size shop and are mainly nesting, then I suggest you process jobs on “time” instead of Room or Quantity, which will allow you a constant flow, eliminate errors and give you more balance and control over product flow.  You can’t tell me every day how many cabinets you can build, but I can tell you how many hours you will be running production.  Manage your boxes into your time.  Just like an engine, all cylinders work in time with each other.  This will also decrease need for managing huge piles of parts on the floor.  Its easier to manage 50 cabinets in flow as opposed to 500 in a smaller shop.  If your nesting and have one machine, and you have parts stacked up on rollers or pallets all over the shop, your losing money, lots of it and its your process that is the problem.

Every time you pick up a part and put it down, it costs money.  The more piles of parts you have, the more management you need to control it.  Wouldn’t it be nice if they managed themselves?  How nice would it be if you came to me, a production manager and asked, where is this cabinet, and I told you, what time it would be on the truck and be accurate?

So hop in, tell us your solutions and find out answers to your problems.  I will moderate this blog best that I can to keep things tidy.

TO SHOE OR NOT TO SHOE?

For those of you nesting, do you have a shoe on your bander for managing the pre drilled cup holes for your doors?  For those of you using a plug for these holes, did you know banders can be made with shoes?  This is a  plate that rides over the hole for you, on the bander, in place of a profile wheel.  If you want to do nesting, this is a item you need to pay attention to.

If you don't have a shoe, how do you do your doors?  Lets see who is really doing it right and who is working around a problem instead of solving it.  I will play the devils advocate and get the brain juices flowing.

We don't nest currently. We have a machining cell in place with 2 Holzma panel saws, a Homag edgebander, 2 Weeke point-to-points and a Homag nested based machine. We have never nested cabinet parts, but this is something that I've thought would be an issue. How do you run the parts through the edgebander without the edgebander "choking" on the hinge cup holes? I wasn't aware of a "shoe" on an edgebander. I'm curious how companies who nest solely handle these issues!?

Shoe? We have been doing the plug thing, which is a pain. I wonder if the shoe is something we can add to an existing edge bander. We have a Holzher Sprint 1321, it's a great machine, does the pre mill thing and does a high quality edge but the 'shoe' sounds great. I suppose we should just contact our supplier to see if we can upfit it?

This is a perfect example of how the little things get you day after day.  Why its necessary to evaluate the entire process before piecing things together.  I love to get shops humming along, following my rule, 1,2,3,4 out the door!

Ok, so I contacted the manufacturer, he said the installation tech should have told us. Imagine that, so now we are on the road to getting shoes. I suppose that means we are not barefoot anymore.

Thank you Craig, about once a week I end up owing you something.

Only once a week??? I'm thinking about once an hour for me!!!

Now lets really bake your noodle, for those of you running medium output, what would you say to processing one cabinet at a time down the line, sorting at the saw?  Imagine all the parts for a cabinet traveling down a conveyor, together!

On the edgebanding issue.  We use to have an SCMI bander and we had a problm with the wheel but when we got our Brandt bander the wheels do not hit the hole for the hinge.

Now is the time to retool, rethink and rebuild!  With the economy finally hitting bottom, up is the next direction, so now is the time to get ready for the rebound.  Most shops are slow, have the time they usually don’t have, to fix all those pesky little problems you always wished you had time to take care of.  It is amazing how many people still will not make this commitment to the company blaming the economy.   It takes money to make money and this is proven over and over.

Those who want to succeed, see this is as the perfect time to make the adjustments.  When the economy is strong again, who will be the most efficient?  Those who can make a better product in less time will certainly do well.  

While there are many companies who are undercutting bids to keep doors open, the simple fact is, this is unsustainable for any length of time and is only a temporary band-aid, but are they retooling during this time?  If they are, chances are, they will come out smelling like a rose.

The people I am working with now have this foresight.  There are many experienced people like myself out there ready to jump in and offer their expertise for retooling and rethinking their process. Rates are the best they have ever been and there are many tax incentives both now and on the horizon, so think about it.  

If you are a fan of reading the trade magazines, you know you have been reading about lean manufacturing and the production process for years now.  Have you done yours?

Machine Drill Heads, what is the good size?  Over the years I have watched countless deals made where a buyer or seller will reduce the size of a drill head on a machine to lower the sale price.  Is this really a savings?  When you stand there and watch a machine hen peck hundreds of holes, you will realize its not.  A good thing to consider, think in your mind the average pattern created for your products, buy a drill head that can drill that pattern the fastest.  Good guideline.

I am looking for labeling options to fit my production, or either better production options to fit my labeling.  We have discussed this many times over the last couple of years and have yet to come up with what we feel is a comfortable solution.  We are not using barcodes from MV in our production line.  The biggest issues are the fact that each end has to have a label and that requires sorting.  As it is now common size ends are stacked together and machined in order according to the job summary report.  No sorting required of these parts required.  We do have machining issues from time to time, but not enough to outway the cost of having to sort 50 - 60 ends in a batch, not to mention the floor space required.  I am constantly pushing to move to the scanning for the point to point, but until I can solve this sorting issue it will be a no go.  Any ideas are greatly appreciated.

Laco, I think the solution is in the overall process.  Step back and look at the big picture to find the solution.  First question, how big is your production runs typically?  What is a typical type job your company prefers to do?  Custom high end commercial work, or high volume boxes like schools or run of the mill standard jobs with architects?

For a larger shops with Cell ines and saw automatically outputing system, arrange Base and Upper Gables, nailers and stretchers with same material in the same sheet and use one label for all the machines stack parts could save the sorting time. The label are mandatory for all the horizontal parts including Top, Bottom, Fixed shelves, adjustable shelves and drawer boxs to reduce the sorting time.

We are really new to Microvellum and we are outputting to a nested CNC.

We are running into a problem when we nest that it is not onion skinning small parts so they end up moving and are no good.

Do we need to turn off common line cutting to get an onion skin?

Any help would be greatly appreciated.

You got it.  Onion skinning isn't designed to work with centerline nests.  

You have two options:  

- Use non-centerline nests with onion skinning

- Use the Tab function with your centerline nests
