Presence Detection on Rotating Lathe Turret
Improved Performance – Consistent presence detection reduced tooling damage and increased throughput
Betty Machine has been meeting and exceeding customer expectations in the manufacture of precision machine parts, CNC and screw machine products for over 60 Years. Attention to detail, accuracy and consistency are fundamentals embedded into the culture and processes established by Betty Machine.
Precision machinery, an expert staff and high-quality raw materials are integral to the production processes at Betty Machine. As material is loaded into a lathe, the operator validates its position and alignment to prevent tooling damage, material loss and production slowdowns. Betty Machine wanted to improve process efficiency by automating this process. The solution would have to perform reliably despite machine vibration, moving components and airborne debris.
Betty Machine chose the SureCross® DX80 FlexPower® wireless network from Banner Engineering. This versatile, highly-scalable solution is built around a Gateway capable of two-way communication with multiple end-point Nodes.
A single Node with an inductive proximity sensor was secured to the lathe turret. The open design of the Node made it easy to integrate a third-party sensor into the application. The IP67 rated enclosure and an added polycarbonate shield provided protection from flying debris. An internal 3.6V lithium battery supplied power to the Node and the sensor. Because the solution is completely wireless, movement of the turret was unrestricted by the addition of the Node and sensor.
The proximity sensor detects material presence and position. This information is communicated to the connected Node and transmitted to the remote Gateway. The operator receives a pass or fail signal dependent upon material presence or absence. The Gateway centralized data collection for Betty Machine and provided reliable two-way communication between the operator and the sensors.
Create point-to-multi point networks that distribute I/O over large areas. Input and output types include discrete (dry contact, PNP/NPN), analog (0 to 10 V dc, 0 to 20 mA), temperature (thermocouple and RTD), and pulse counter.
