The Benefits of Probe Technology
In manufacturing, probe technology is one of the most reliable sources to ensure machine tools are efficient, accurate, and in good working order to machine a quality product. Probing systems are ideal for reducing setup times because they can quickly complete routine measurement and geometry tasks.
In comparison to manual measurements, probes are an excellent choice for confirming the precise location and size of a part or fixture, with few errors. When setting up the automation process for a part, or parts, to be machined in a single setup probes shift from being a luxury add-on to an essential component. Confirming the correct positioning of parts loaded by an automated system, such as robots, is critical to precise, accurate machining. Typically speaking, automated probe technology is usually the fastest way to get accurate measurements and dimensions.
Process control: By measuring a part and monitoring it throughout the manufacturing process, machinists can monitor machined features to determine errors. For example, tool deflection when using a difficult-to-machine material can lead to a reduction in material removal rate than expected. Generally, when this happens it leads to reworks that take up time. However, a probe can determine when a part is not within tolerance during the machining process and will direct the machine tool to alert the machinist or automatically readjust the cutter to complete the job.
Tool Setting: Just as it is important to ensure that the position of a machine tool is accurate, it is equally important for parts. Small flaws, whether in a tool or tool holder, can divert a pass, harming tool and part and machine alike. Similar to how probing can identify small flaws during part setup, probes can accurately distinguish disparities in tools or tool settings, safeguarding the process from broken tools and downtime.
Complicated Parts Inspection: Machining technologies, for instance, 5-axis machining and additive manufacturing, have allowed manufacturers to produce parts with complex geometries. As a means of being cost-effective, such parts need to be inspected. In particular, multi-axis probing is exceptional at certifying precision holes and complex shapes in any machine. Similar to easy-to-machine shapes, creating these types of measurements on the machine enables the machinist to quickly alter the process to make up for any errors during the process.
Hybrid Manufacturing: With additive manufacturing becoming more prevalent in the industry, machine shops are starting to invest in hybrid machine stations suitable for additive and subtractive manufacturing. This investment allows manufacturers to benefit from the design freedom of additive manufacturing machines and the accuracy and precision of a machine tool.
Although most machines benefit from in-process analysis, this step is mandatory for hybrid machines. Because hybrids print the forms that are to be machined, they must complete several operation processes. It is essential to manage the tolerance stack up across the various operations. Before machining, manufacturers must first confirm that enough stock has been produced. The next step is to enhance the location of the stock for each machining pass, and the last step is to confirm that a good amount of material has been removed before moving on to the next step.
To take advantage of the benefits of probe technology machine shops need to be able to respond and adapt to the data that the probe provides. Probe technology allows its users to align parts, measure complex geometric areas, confirm tolerances and calculate alignments, without having to move the part from the machine.
Skilled machinists are required to respond to probe data in many operations. When users of probe technology enable the software to verify tolerances without human intervention it allows for efficiency, not only in machining but can work for automated technology such as lights-out machining also. With the benefits that probing provides, shops will look to implement such technology into their process.
