Probing: Logically, the smaller the part is, the higher the need for accuracy is – because physically there’s less room for error. Datron offers a variety of integrated probing options that promote accuracy and quality control and even provide manufacturers with a product development tool by enabling reverse engineering.
Datron’s optional, but integrated Z-Correction Probe recognizes irregular work-piece topography and compensates for it dynamically. It does this by taking measurements along the surface of a blank and feeding that data into the machining controller. The controller automatically adjusts for uneven surfaces or work piece position. Through this process, job setup times are reduced and piece/part rejection is minimized.
With the addition of the 3D Extension, the Z-Correction Probe locates parts and material irregularities in the X, Y, and Z co-ordinates, finds centers of holes and bosses, pre-measures blanks before the machining starts, compensates for material variations, feeds data into ISO 9000 information chain for quality control, and even allows for the reverse engineering of many parts.
The omni-axis Renishaw TP20 probe is ideal for complex part measurement such as engraving a logo onto a rounded surface. Ordinarily, 3D programming would be necessary to accommodate surface depth changes and ensure an even depth engraving. With the TP20, the surface is scanned and irregularities or surface changes are automatically managed in the machining data without 3-D programming. The TP20 features a 6-way, kinematic, touch-trigger probe system to significantly improve cycle times.
