The invention relates to a dental milling machine which has a closed milling chamber (12). Said milling chamber has an air inlet opening and an outlet which are substantially opposite each other relative to the milling chamber and generate an air stream. Said air stream sweeps over a machining area in which a milling tool subjects the workpiece to a milling machining step. One end of the milling chamber (12), in particular the front end, has a door that can be opened. The base (42) of the milling space (12) runs at least partially at an angle and in particular is rounded off and the outlet (40) is connected to the lowest region of the base (42).

Methods and devices are provided for detecting connecting elements, in particular friction drilling screws, in mechanical joining and forming processes in which an error event in the process was identified. The method includes moving a carrier component for the connecting element toward a workpiece to determine a contact point of the connecting element on the workpiece. This feeding step is carried out as a next method step after the error event is detected and ascertains whether the contact point is detected within a predefined permissible tolerance in order to determine whether the connecting element is still located in a feed head.

A method to set up the parameters of solder paste screen printer while in a new product introduction (NPI). The method includes establishing a solder-printing database of a predetermined product and a database of different specifications of products, and training a first prediction model by reference to a solder paste screen printer (SPSP) and a solder paste inspection (SPI) based on the solder-printing database. A second prediction model is trained by reference to the SPI based on the database of different products. The method further includes predicting parameters for products with different specifications under multiple sets of printing parameters based on the first and second prediction models. An objective function based on the predicted measurements is established, and a specification of a product and a printing expectation parameters are input to the objective function for outputting many sets of printing-suggestion parameters of the new product.

The present disclosure relates to systems and processes for controlling the relative positions or phasing of advancing substrates and/or components in absorbent article converting lines. The systems and methods may utilize feedback from technologies, such as vision systems, sensors, remote input and output stations, and controllers with synchronized embedded clocks to accurately correlate component placement detections and placement control on an absorbent article converting process. The systems and methods may accurately apply the use of precision clock synchronization for both instrumentation and control system devices on a non-deterministic communications network. In turn, the clock synchronized control and instrumentation network may be used to control the substrate position. As such, the controller may be programmed to the relative positions of substrates and components along the converting line without having to account for undeterminable delays.

The present invention teaches a process of measuring and grinding tools in can/cylindrical body production, allowing reduced production downtime, reduced cost and a predictive tool wear capability, which process allows more accurate stocking of tool inventory by means of tracking individual tools in use and providing advanced diagnostics to the tool room. This includes not just out-of-spec alarms from QA but also predictive alarms regarding cans produced by each tool, in-spec can weights and wall thicknesses, information on tool sizes being used in production, tools in inventory, pulled from inventory and other stock balancing information. The invention further teaches a system of equations for prioritizing grinding to maintain optimum tool inventory levels.

A technique is capable of preventing particles from adhering onto a wafer when a lid is attached or detached from a pod. A substrate processing apparatus includes: a placement part whereon a substrate container is placed; a guide part constituting a lid opening/closing space; a gate part separating the lid opening/closing space from a transfer chamber; a lid opening/closing mechanism provided in the lid opening/closing space and configured to attach or detach a lid of the substrate container; a gas introduction mechanism configured to supply a gas into the substrate container; a monitor part configured to monitor and adjust an inner pressure of the substrate container; and a controller configured to: (i) control the lid opening/closing mechanism; and (ii) control the monitor part to maintain the inner pressure of the substrate container higher than an inner pressure of the lid opening/closing space while the lid opening/closing mechanism detaches the lid.

The shapeable hot scoop is required to remove material by cutting and scooping. It is necessary to change the shape of the scooping tool automatically. This invention proposes several mechanisms for changing shape of the scooping tool automatically. Method of detection & correction of cutting wire lag is also proposed in this invention.
