How to Conduct a Test Run

The saying “measure twice, cut once” has been around shops for a long time because it still holds true. In waterjet cutting, a small setup mistake can become expensive quickly, especially when the material is valuable, customer supplied, or difficult to replace. Before the actual cut begins, operators need confidence that the nozzle is positioned correctly, the part fits within the available material, and the machine will move the way the program intends.

That is the purpose of a test run.

On an OMAX waterjet, IntelliMAX software gives operators tools that help check setup before committing material, water, abrasive, and machine time to the cut. Two of the most useful features for this process are the low pressure locating beam and the dry run function. Together, they help operators confirm position, preview movement, and reduce the chance of avoidable cutting mistakes.

Why Test Runs Matter in Waterjet Cutting

Abrasive waterjet cutting gives manufacturers the flexibility to cut a wide range of materials, including metal, glass, stone, composites, plastics, rubber, and foam. That flexibility is one of the reasons OMAX waterjets are used across so many manufacturing and fabrication environments.

But even with a highly capable machine, the setup still matters.

If the material is not positioned correctly, the nozzle starts in the wrong location, or the toolpath does not match the available cutting area, the result can be wasted material and lost production time. In some cases, the mistake may not be obvious until the cut has already started. By then, the material may already be damaged and the job may need to be restarted.

A test run gives the operator a chance to catch those issues before they become costly.

Position the Nozzle with the Low Pressure Locating Beam

The first step in conducting a test run is making sure the nozzle is where it needs to be. Accurate nozzle positioning is important because the cut depends on the relationship between the programmed path and the actual material on the table.

OMAX IntelliMAX software includes a low pressure locating beam that helps operators position the nozzle with greater accuracy before cutting begins. Instead of relying only on visual estimation, the operator can use the locating beam to confirm the starting location and verify that the cut will begin where expected.

This can be especially valuable when working with expensive material, remnants, irregular stock, or customer supplied pieces. In those situations, there may not be much room for error. A small positioning mistake can mean the part runs off the edge, cuts into the wrong section, or wastes material that cannot be easily replaced.

Using the low pressure locating beam helps reduce that risk before the cutting process starts.

Check the Material Before the Cut

Once the nozzle location is confirmed, the operator should also check that the material is properly placed within the cutting envelope. This is where the “measure twice” part of the process becomes practical.

Before starting the cut, operators can confirm that the part fits on the available material, that the starting point makes sense, and that there is enough clearance around the programmed path. This quick verification step helps prevent common setup issues that can affect part quality or create scrap.

For job shops and manufacturers working against tight schedules, this matters. A preventable error does not only waste material. It can also consume machine time, delay the next job, and create extra work for the operator.

Use Dry Run to Preview Machine Movement

After confirming the nozzle location and material placement, the next step is to use the dry run feature in IntelliMAX.

Dry run allows the operator to run the program without performing the actual cut. This lets the operator watch how the machine will move before water and abrasive are used. It is a simple way to preview the cutting path and look for potential problems before production begins.

During the dry run, the operator can confirm that the machine movement matches expectations, that the part stays within the material area, and that there are no obvious setup or programming issues. If something looks wrong, the operator can stop, adjust the setup, and check the program again before cutting.

That small step can help prevent much larger problems later.

Catch Problems Before They Become Costly Mistakes

The value of a test run is not only in finding major errors. It is also in catching small issues early.

A part may be too close to the edge of the material. A start point may need to be adjusted. A programmed path may not line up with the way the material was placed on the table. These are the kinds of issues that are easier to fix before the cut begins.

Once cutting starts, the cost of an error increases. Material may be damaged. Abrasive may be wasted. The machine may spend time on a job that needs to be restarted. Operators may need to reload material, adjust the program, or remake the part.

By using the low pressure locating beam and dry run feature together, operators can build a simple verification step into the normal workflow. That helps reduce waste, improve confidence, and support more consistent production.

Cut with Confidence Using IntelliMAX Software

A test run is not about slowing production down. It is about helping operators start the job correctly the first time.

OMAX IntelliMAX software supports this by giving operators practical tools to verify setup before cutting begins. The low pressure locating beam helps confirm nozzle position. The dry run feature helps preview machine movement. Together, they help operators apply the “measure twice, cut once” approach directly to the waterjet cutting process.

For experienced operators, these tools support the setup habits they already use. For newer operators, they provide a more repeatable way to check the job before starting the cut. That can help reduce uncertainty and make the cutting process more predictable.

Whether a shop is cutting high value material, customer supplied stock, or everyday production parts, test runs can help protect material, reduce mistakes, and keep work moving through the shop.

With OMAX IntelliMAX software, conducting a test run is a practical way to improve setup confidence before the first cut is made.
