Measuring Edge Wear Consistently: Three Practical Methods Compared

How can a shop measure edge wear so that numbers from different weeks and different people can be compared?

Buyer question

We want to compare edge wear between trucks and between suppliers, but each person measures differently. How can we measure wear the same way every time with simple tools?

Short answer
Pick one method, fix the measuring points and record the same fields each time. The three methods below suit small shops; each has trade-offs. I do not cite a study here, and no wear figures are given.

Three methods compared

Method How Strength Weakness
Height gauge Measure remaining height at marked points with a simple gauge or caliper Direct, cheap, quick Depends on consistent points and a clean surface
Photo with scale Photograph the edge beside a ruler from a fixed distance and angle Creates a visual record; easy to share Camera angle and light change the picture
Weigh-in Weigh the edge when new and again when removed One number for the whole edge Needs a scale; hides where the wear occurred

Making any method consistent

Three methods measure the same thing differently, and the value comes from using one of them consistently.

  1. Mark the points. Choose a few positions, such as both ends and the middle, and mark them with paint or a punch.
  2. Clean first. Remove dirt and ice before measuring.
  3. Use the same tool. Keep one gauge, one scale and one camera setup for the fleet.
  4. Record the same fields. Date, truck, route, hours or storms, edge ID, reading at each point.
  5. Take a photo as well. A picture backs up the numbers and helps if a reading is questioned.

Choosing

If you want one simple measure, start with the height gauge at marked points, add a photo and use the weigh-in only for special trials. Keep it light, because a method that takes too long is dropped within weeks.

What to do with the numbers

Plot or tabulate wear against hours, storms or route. Look for trucks or routes that stand out, and ask why before you change anything.

A record template

Keep one line per edge: edge ID, truck, route, date fitted, date removed, hours or storms, readings at points A, B and C, photo file name and notes. Print it as a card kept in the shop, or hold it in a shared sheet. After a season, you will have enough rows to compare trucks, routes and suppliers on the same basis, and to decide which to trial next.

Boundary: No published study is cited and no wear values are given; the methods are general shop practice.

↳ Replying to SENTHAI Editorial Team

Do the measurement the same way at the same point of the shift, with the edge clean. Mark the points and take a photo with a ruler in frame. If two people measure, have them compare readings at the start so that small habits do not turn into differences in the data.

↳ Replying to Field-check perspective

Put the measurement into the routine, for example at each Friday check or each change. Keep the record where the whole shop can see it. A simple table on paper works as well as a spreadsheet, if it is filled in. Review the numbers monthly and remove steps that nobody uses.

↳ Replying to Maintenance perspective

Consistent measurement is what makes a trial of a new edge meaningful. Measure the control and the trial edge in the same way over the same period. Without it, any difference in wear can be put down to the driver or the route, and the result does not help your purchasing decision.
