Techniques are described for receiving manufacturing data and events over real time and non-real time interfaces and associating the data with one another. In one example, real time data is received, the real time data associated with a counter value assigned by a precision counter. The received real time data is stored in a storage buffer, and non-real time data is received, where the non-real time data associated with a counter value assigned by the precision counter. In response to receiving the non-real time data, the buffer is searched for real time data having a matching counter value and, in response to identifying stored real time data associated with a matching counter value, the non-real time data is associated with the real time data based on the match. Data packages are generated including related real time and non-real time data associated with matching counter values.

A processing executing unit of a control device is configured to set the number of blocks to be read indicating the number of blocks to be read from a storage unit per unit time and a fan rotational speed of a fan motor in accordance with the amount of allowable machining error or a feed rate of a table that is inputted by an operator, and further configured to read a machining program from the storage unit block by block at the set number of blocks to be read and cause a fan control unit to perform a process to drive the fan motor at the set fan rotational speed.

To provide a numerical controller that can detect the position at which the look-ahead blocks used to determine an acceleration/deceleration operation is insufficient in a machining program in order to stabilize feed rate, cutting speed and other factors. A numerical controller includes a program execution unit that executes a machining program, a program look-ahead unit that looks ahead at the machining program in parallel with execution of the machining program, a look-ahead blocks calculation unit that calculates a look-ahead blocks, which is the difference between a first sequence number that is the number of a block being executed by the program execution unit and a second sequence number that is the number of a block that is looked ahead by the program look-ahead unit while the machining program is being executed, and an exhaustion block detection unit that detects an exhaustion block, which is a block at which the look-ahead blocks falls below a prescribed value.

Techniques for comparing two or more sessions of a manufacturing process are described. In one example, a particular metric associated with execution of a manufacturing process is identified, the particular metric evaluated in a plurality of manufacturing process sessions for at least one manufacturing process. A particular session particular session from the plurality of manufacturing process sessions is selected as a baseline session, wherein at least a portion of the remaining plurality of manufacturing process sessions are to be compared to the baseline session. In a primary portion of a presentation area, a visualization of the values of the identified metric associated with the particular session are presented. In a secondary portion of the presentation area, visualizations of the values of the identified metric associated with at least a portion of the other manufacturing process sessions from the plurality of sessions is presented.

A connection between values of the 2D metric set and the machine-related data of the 3D visualization is determined and, based on the connection, the selected 2D metric set is incorporated into the 3D visualization of the machine-related data.

A numerical controller sequentially reads blocks contained in a machining program, analyzes the read blocks to identify a block that causes an alarm based on mismatch criterion information stored in advance, and generates alarm cause data. The numerical controller then generates, based on the generated alarm cause data, at least one set of proposal patch data for correcting the machining program in such a way that the cause of the alarm is solved and generates a corrected machining program that is the machining program to which the generated proposal patch data is applied.
