I was intrigued by a recent discussion on the PMPA’s Manufacturing Listserve. It involved whether programming for machines is best handled by operators on the shop floor or “from
the office” by the engineers or programmers.
There were many opinions, many good points raised, and many great reasons given to support each philosophy. However, there was one idea not brought up that I want to explore — our industry’s fixation on “leaning out the cost of improvement.”
No one would argue that the best way to get the program into the machine is the one that is most direct and has the least amount of waste. Looking at events discretely, as an activity, makes it possible to wring out the last little bits of waste.
No one would argue that the work should be performed at the organization’s lowest level that is qualified to do that work properly. This is a corollary of the principle of “operating at highest and best use.” Our people and equipment are creating the greatest value when they are operating at their highest and best use.
When you compare the hourly rate of the engineer/programmer to the hourly rate of the machine set-up operator, it looks like the best decision is to let the lowest-cost employee “fist in” the program. But is it?
Depending on how long a job is going to run, the best investment may be to have the engineers invest some additional time on the program. They can minimize all waste and redundancies in the code and get the job to run at the absolute lowest cost possible.
On a short-running job, there is not much point in investing a lot of time to absolutely optimize the code. The few hours that the machine will be running may not be enough to pay for the programmer’s time to optimize the job. So, having the shop guy enter the code as is makes great sense—dollars and sense.
However, if the job is going to be on the machine for weeks, on a much longer run, why wouldn’t you want to invest in a little more of the engineers’ or programmers’ time? That allows you to exercise their creativity, assure flawless execution and use the lessons they’ve learned to preplan and assure the lowest possible machine time.
To my mind, the following are more relevant questions for our businesses: Do we have a policy for investing in anticipation? Do we have a policy for investing in process optimization? Where should we spend a little more of our intellectual capital to achieve greater value for our shops?
Are we ruled by the “tyranny of urgent” to just get the programming done and into the machine in the least amount of time and at the lowest cost? Or, are we driven to create the greatest value for our companies by methodizing the engineering and more rigorous pre-planning?
The very best managers are not those with great coping skills. The very best managers have the ability to anticipate and eliminate potential problems, not just cope with them. Do we have a line item for investing in anticipation? Or, do we just try to minimize each cost as we encounter it, without looking at the system as a whole?
Leadtime orders are virtually non-existent these days. Every customer wants his or her job today. But how many more jobs could we fit in if our longer-running jobs had an additional half hour of “what if” engineering creativity applied to their optimization? How much more profitable might we be by the end of the month?
Looking to minimize the costs of a single activity (such as getting a program into a machine) is a good idea. Looking to maximize the value to the enterprise is a great idea. It’s also an idea that just might be contrary to minimizing the cost of any single activity.
Are we truly designing our work to minimize overall shop cost, or are we succumbing to the tyranny of the urgent to get individual tasks completed quickly?
User-friendly inspection software for CNC machining centers was shown at IMTS 2024 monitoring measurements between and after machining while performing SPC based on recorded measurement values.
Marubeni Citizen-Cincom’s tooling and accessory workshop offers a chance to learn more about ancillary devices that can boost machining efficiency and capability.
Starting on Thursday August 8, 2024, PM will begin “gating” its premium content, asking all new website users to provide some information about themselves — name, title, employer, email address — before they are provided free access to the content.
We are doing this because the ways PM’s audience finds and accesses our content is changing. Google’s search algorithms, increasingly, make it difficult to connect PM’s content with the people who might make use of it. On top of that, generative AI like ChatGPT is serving up PM content to internet users without attributing that content to PM.
As a result, it has become increasingly important for PM evolve its audience development strategy and learn as much as possible about who is accessing our content, what content they are accessing and how they are accessing it.
With this audience development strategy, we hope to do two things:
First, we will be better able to deliver directly to our audience the editorial content that aligns with the machining materials, processes and technologies that interest them.
Second, we will be better able to connect the materials, equipment and services our advertisers supply with the audience that is most interested in them.
PM plays a distinctive role and has earned a place of esteem within the focused and specialized industry it serves. Large developments in the media landscape are forcing us to change the way we communicate with our audience. We are confident that our audience values the role PM plays in their professional lives and will join us in this effort to stay connected to them.
We thank you for your continued interest in and support of PM and welcome any questions you might have about the brand’s new content gating strategy.
