The automotive industry expects more support from suppliers in quality assurance for assembly work. As a result, suppliers in the automotive industry are looking to automation partners to better meet this technology demand while delivering faster. Mechanical engineering companies need to make greater use of intelligent subsystems in their standard tasks to speed up time-to-production and productivity in order to remain competitive in the market. For example, select subsystems for stamping and joining.

Intelligent subsystems for mechanical engineering
KMS Automation GmbH was founded 25 years ago and specializes in automation technology, fixture construction and special machine construction. The company's headquarters in Schlamberg-Woldmüsingen in the central Black Forest employs around 115 people. The company's desire to standardize its stamping and joining processes came from a global automotive supplier.
Due to the high cost of the in-house development concept initially conceived by KMS Automation, KMS Automation accepted the offer of long-time system partner Bosch Rexroth to participate in the joint development of the intelligent press-fit function kit subsystem. "We seized this forward-looking opportunity," says Peter Schneider, the company's founder. "The two sides have worked closely and constructively from the very beginning."
Standardize with the help of the Smart Press-Fit Function Kit
In the production system, the suite of intelligent functions forms the core component of the first of the five assembly stations. The subsystem consists of several components, including electric cylinders, servo motors, servo drives, industrial PCs, and force sensors. In addition, KMS Automation uses Bosch Rexroth screw drives and linear guides, as well as aluminium profiles, on the assembly line. The main task of the press-fit kit is to electromechanically guide a tube about 250 mm long through the inside of the aluminium oil pan and press it into the space with a defined force. Later, the vehicle's drive shaft will pass through this glued tube. In addition, the suite of intelligent functions needs to monitor the connection process and transmit the process data to higher-level IT systems for quality assurance.
Plug-and-play solutions for a range of applications
In the past, KMS has primarily used hydraulic solutions for similar wide range of pressure value applications, which is significantly more complex. Klaus Wurster, Managing Director of KMS, says: "The complete multifunctional subsystem from a single supplier will save us valuable time in the future, which we can use to develop innovative solutions." "We have saved the most time in engineering and commissioning, and we have also benefited from standardization in terms of procurement and service," he added.
The modular design of the Smart Function Kit supports KMS Automation in standardizing applications in the pressure range from 2 to 70 kN. Axial or parallel motor mount versions allow for flexible integration with a variety of system designs.
Flexible software development
The groundbreaking software features of the Smart Joining Function Kit include a commissioning wizard, a graphical programming module, a control panel that displays current process information, and a range of functions for diagnostic, visualizing and evaluating processes. During a fully guided commissioning process, the software assistant automatically sets the parameterization for the drive controller. Visually define processes using ready-made modules that are arranged by simple drag-and-drop and then given parameters.
Connectivity and security
With the help of function blocks, the line control system can be connected quickly and easily via a fieldbus. The Smart Function Kit also supports the OPC-UA standard. The suite of smart functions provides more options for data access with analog and digital inputs/outputs, as well as the ReST API. With open interfaces and the process information available through open interfaces, mechanical engineering companies are able to meet quality assurance and documentation requirements in a faster and simpler way than ever before.
KMS Automation uses the safety control system as the basis for the system's safety functions. PROFIsafe is used for safe communication between the safety device and the suite of smart functions, in addition to ensuring that the specified maximum safety speed is not exceeded. If someone enters the perimeter raster, the transition to a safe stationary state is activated and monitored.
Reduce complexity, save time and money
For Klaus Wurster, the suite of intelligent functions is an important step in simplifying previously worked and cost-intensive tasks. "Many of our systems now have a purely electromechanical design. This not only reduces machine complexity, but also gives us greater freedom and greater precision in process design. Thanks to the finely adjustable electronics, we can use different speeds, which, in addition, guarantee quality and reduce cycle times. With slow probing, we can check if the workpiece has been inserted and then punch and join it with high precision. ”
The changes made to the software during the further implementation of the joint development process benefit not only KMS Automation, but also all customers, as Bosch Rexroth supports the free download of all updates. With subsequent software releases, data storage will become faster, enabling customers to further reduce cycle times. Klaus Wurster said: "We are pleased to have a successful partnership with Bosch Rexroth and to be involved in the in-depth development of the subsystems. The cooperation with Bosch Rexroth is a future-oriented cooperation. Given the far-reaching implications of simplifying the design and saving time, we wanted to use modular subsystems and proven components from our automation partners whenever possible. ”
