In October 2021, it seems like most shops are pretty busy which is awesome! Although I still hear from multiple shops that they are slammed on some of their machines (5 axis mills) and not nearly as busy on others (their 2 axis lathes for example). If this is sometimes or often true in your shop, there are some things you can do to help ensure all your work cells are equally busy. 

A lot of shop owners I talk with tell me that they quote all their jobs with a single shop rate. Could be $60, $80, $120, or more per hour. (They do job costing this way too...oh heavens!) Whatever the rate is, they use it and apply that same hourly rate to any job they quote and any machine it will take to make the part. While this seems easy and simple at first glance, it will result in an unfavorable mix of work that isn't very profitable at the end of the day. Let’s look at why.

Most shops have a mix of different types of machines that have different capabilities and different costs. Some are pretty basic and relatively inexpensive, while others are much newer, fancier, and more expensive. Consider a G550 Grob that costs $700,000 vs a Haas ST-10 for $50k. Those are very different machines and should be quoted at very different rates. Do you know what’ll happen if you quote all your jobs at $100/hr?

  1. Your high-end machines, which should command a premium rate, will be stuck being 100% overloaded with low margin (or negative margin) work.
  2. Your low-end machines will get a few jobs but will generally be pretty underutilized because you’re bidding a higher rate than the market will bear for that type of work.

If your competitors are bidding high-end milling work at $180/hr and you are bidding $100/hr you’ll be the winning bid most of the time, you will be leaving a lot of money on the table that could be in your bank account! Conversely, if you bid lathe work at $100/hr and your competitors are bidding $60/hr then you’ll rarely win those jobs and your lathes will sit idle much of the time. This is not what you want in either case!

The ideal pricing model in a job shop is one where you can fill up all your machines with work that is a good fit for your shop and at the highest prices that the market will bear for that type of work and work center. Part of understanding the maximum price you can sell a part for will include understanding what your costs are, and the difference will be your profit margin.

Of course, every shop has its unique niche which will determine what the market rate is e.g. 2 axis turned mild steel parts for the heavy equipment industry will generally command a much lower rate than 5 axis milled titanium parts for the space industry, so please keep all that in mind. The market price is also heavily influenced by lead times, material costs, and many other factors which are all important to factor in.

Let’s look at a generic job shop that has a combination of lathes and mills that also does value-added assembly work (and keep in mind these example rates are used for illustrative purposes relative to one another, not absolute! Your rates may vary widely.)

Consider a combo part that starts with turning, gets some complex milling features, and then has 20 helicoils installed. To get the most accurate cost to factor into the price that the market will bear, you should be bidding each category of machine time at different rates. I’d even argue that you should be charging more for your labor for programming and setup time than you do for your machine operators, independent of which machines they’re using. This type of pricing is called Activity Based Estimating which is very closely related to Activity Based Costing or ABC.

At the end of the day, if you have enough staff to run your machines (not a given at all in 2021) then you want to make sure that all your work centers (machines and otherwise) are being estimated at rates and prices that will win the right amount of work at the highest prices. You must then be able to estimate the costs accurately and apply the right amount of margin to just win the work without being too high priced. So do some research, some lost bid analysis, ask your friendly competitors, inquire in machining forums, and crunch the numbers yourself as to what you should be bidding for different types of machines and different types of work. By being more data-driven, you can help ensure all your work cells and people are equally busy by winning work that is producing good margins and contributing to your overall growth and revenue targets.

 

How can ProShop Help?

ProShop’s estimating module is exceedingly fast at creating very accurate activity-based estimates. You can pull pricing levers for nearly anything you can think of: Different work cells, different types of labor activities (such as programming, planning, setup, running, inspection, fixture creation) differing markups on materials, BOM items, overhead rates, sales commissions, and more. So you can be as precise as you want to be, and with our Rapid Templates, you can generate these precise estimates in just a few minutes. Clients have told us that estimating with ProShop is up to 3x faster than their old methods of using Excel or old ERP systems.

[/vc_column_text][vc_column_text]“But Paul, it’s too expensive to put a computer at each of my work centers! I just can’t afford that. Right now my employees track their time with a shared computer we already have out in the shop.”

I hear this objection all the time when discussing what’s involved with going paperless and using ProShop. They are typically using just paper only, or another paper-traveler-based ERP and they have a couple of shared terminals in the shop to track time and log parts on their jobs. On the face of it, it’s a legitimate concern. If you spend $350 on a computer and mounting hardware for 15 CNC machines, that’s over $5K! That’s a good chunk of change. But let’s dig into the real numbers and see if it is actually that expensive

I’ll start by giving credit to Gary Connor for his awesome article on the "ROI of Lean". His article was inspiring to me for being such a succinct and easy-to-understand approach to calculating the ROI of removing waste from an organization. I highly recommend you read it first.

Many shops have a paper-based ERP system, with shared terminals placed throughout the shop where employees can go scan into and out of a job, log the number of parts they made, etc. It’s a straightforward process and one they’ve done for years, so they are comfortable with it, and it’s kind of the expected behavior and cost Home - buy oxandrolone 20mg, natural anabolic bodybuilding - een executive club injectable steroids benefits of soy all about culturism and fitness. of doing business. But, as Gary points out, if they crunch the numbers of the cost of this activity, they may think differently about it.

Let’s use a typical example of a shop with 18 machinists - 15 on days, and 3 on nights. (These numbers came directly from a Coastal Machine, a ProShop client who recently went fully paperless in the shop.) A low volume, high mix job shop. On average, each day, the employee has to go to the shared PC three times with an average of 2 jobs per day, once at the beginning of the day/job, and once at the end of the first job, where they also log into the second job, and then lastly once at the end of the shift. The process of walking from the CNC machine to the computer, doing the work at the terminal, and walking back only takes 3 minutes. (They say this is a very conservative number! We all know that those trips across the shop will invariably include stops to talk with someone, grab a coffee, or something else - and it could easily be 5-10 minutes before they get back to their machine!)

So those 18 machinists, running 5 days a week, with 3 round trips to the computer to track time/parts per day, multiplied by 3 minutes per trip, that’s 810 minutes per week, 13.5 hours per week, or 702 hours per year. At $30/hour per employee, you’re paying them a total of $21,060 per year just to walk back and forth to track time. And at $125/hour for machine time, that is $87,750 of lost revenue per year! So you’d be able to pay back the cost of the computers in about 3 weeks!

And this is just a drop in the bucket compared to the real cost of having machinists leave their machines to look for tooling, fixtures, job travelers, etc. By providing all necessary items, kitted, and prepped at a machine, along with digital visual work instructions, and digital inspection forms, it’s very possible to cut 50% or more out of a typical setup time. You can read a blog post about that here, and watch a webinar about it, and download a PDF guide here.

So in summary, the real cost of paper-based workflows, and shared computers is the mostly hidden cost of lost revenue and paying your employees to walk around your shop. You want them to keep your spindles turning as often as possible and making chips! Small investments to achieve that goal will always have a very positive ROI.[/vc_column_text][/vc_column][/vc_row]

[/vc_column_text][vc_column_text]When you get a new order in your job shop, the clock starts ticking. You’ll never have more lead time to get that order delivered on time than you do today.  Customers want everything faster these days, yet everything seems to take longer.  Raw materials take longer to acquire; outside process lead times are lengthening.  It’s imperative that you get things moving as soon as possible while also following a thorough and robust process for risk mitigation, contract review and order confirmation.  When we ran our shop Pro CNC for over 17 years, we continually worked to refine this process making it faster and smoother.

The key for us was getting the order in front of the right people as fast as possible who can make the important decisions about what needs to be done now, what can wait a little bit without compromising risk, and what really needs to be vetted by others before making any decisions.  If the work is repeated and has been made in the shop before the process can be dramatically short-circuited.  If it is brand new work, it’s more critical.  Here are some key items to consider.

1 Launch every item that has a long lead time that may impact delivery. Raw materials, custom tools, special hardware or BOM items can all be on that list.  If your engineering/manufacturing departments aren’t involved with the estimating process, then it is critical for them to review the estimated plan and either confirm or change the plan.  Once this is done and specific details about those long lead time items are well defined, then get them moving.  Issue POs to your vendors on the spot or immediately after the meeting.

2 Make sure the equipment specified in the estimate/shop plan is correct and that it will available when needed to make delivery on time. Are there any special tools, fixtures, and inspection equipment you will need, and will it be available when the job is running? To the best of your ability, confirm you’ll have the staff you need at the time for set-ups, inspection, running, etc. Make contingency plans if any of them seem at risk.

3 If you don’t already have firm quotes from your vendors for purchased items or outside processes, send out RFQs now asking for price and lead time. You may gather valuable information that could derail your plan later in the process which you can make contingency plans for now. Make sure this information is Inicio - ejercicio para aumentar o reducir el volumen, aumentar o reducir el primer culturismo - comunidad de desperdicio de alimentos de los ángeles Aplicacion medica Kamagra sha gym sri lanka bodybuilding , power training , workouts, sports, schedules and many more. stored in a way which is accessible to everyone that needs to know it down the line.

One way to do all this work quickly we called the War Room – This is a process where key stakeholders gather and review all incoming jobs within minutes or hours of a customer purchase order being received. Staff from engineering/manufacturing, quality, planning, estimating and customer service or sales should attend this.  With a well-defined process these meetings can be fast and nimble.  It is a great place to get buy-off from all departments for risk mitigation and contract review.

This work can also be done in parallel rather than in a group. But ensure that it happens very quickly.  Install systems that facility quickly finishing these items and make sure people are alerted if something is sitting in the system too long.

We eliminated individual offices and everyone sat together in one room so communication was as fast as possible. Walls are barriers to fast throughput.

Before this process is even done, make sure the next departments that will be working on these jobs know they are coming.  Whether it’s detailed programming work, QC/QA review, or any other department in your company workflow, giving them advanced notice of work flowing into their queues will allow them to best plan resources and ensure your jobs have the best launch into manufacturing.

Our shop management system ProShop has tools built-in to handle all of these processes and ensure that nothing is waiting so you can cut lead times, get your work flowing faster, and focus on throughput.  But these common-sense principles can be applied to any company using any system.  The important part is continuously improving your process and focusing on performing better for your customers every day.
