A sheet material machining system includes a sheet material machining machine which is configured to machine a workpiece to produce a machined workpiece that includes a plurality of products and a residual material. The machined workpiece is configured to be placed on a sorting table. The plurality of products are configured to be placed on a temporary placement table. At least one product among the plurality of products are configured to be placed on a discharge table. A carrier includes an attracting actuator and a mobile actuator. The order management processor is configured to control the carrier and includes a storage configured to memorize a layout of the plurality of products in the workpiece. The plurality of products are associated with an attracting order.

Sheet material machining system and method for processing workpiece

A turning tool is arranged at a tool spindle () of a composite working lathe () to improve working efficiency. A composite working lathe () includes a first workpiece headstock () placed on a bed (). A chuck () of a workpiece spindle () is rotated as holding a workpiece (K.sub.). A tool headstock () arranged at a carriage () is rotated about B-axis while being linearly moved in the directions of X-axis, Y-axis and Z-axis. The tool headstock () operates a mill tool () and includes a comb-shaped cutting tool rest () having turning tools attached at the opposite side of a housing in a comb-shaped manner, so that turning processing can be performed with tool indexing in a short time.

The object of the invention is to provide an inverted vertical lathe comprising a device for replacing collets automatically, and having a detector for detecting that the collet has been gripped correctly. A chuckmounted on a headstockgrips a colletin a replaceable manner via a tapered boreprovided to the end thereof. A collet end face eccentricity detectorcomprises a detecting member (sensor)fixed to the end of an arm. The detecting memberdetects the eccentricity of the end faceof the colletin a contactless manner. A variation pattern of the eccentricity occurring when each colletis gripped correctly by the chuckon the main spindle is detected in advance, and this pattern is compared with the variation pattern of the eccentricity detected by the present detection, and thus, whether or not the collet has been gripped correctly is detected.
