For a more complete understanding of the present disclosure, and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, wherein like numbers designate like objects, and in which:
Typically, a CAM postprocessor developer creates a new postprocessor from scratch. It can be very difficult to reuse existing functionality from postprocessors developed by other people.
Disclosed embodiments include a library-based model that overcomes this problem. A disclosed postprocessor includes various levels. These levels can be protected against reading and modification, but functions of lower levels can be overridden to implement their own structures. This level concept allows exchanging underlying levels and therefore updating and re-using existing code.
Further, to make adaptions of a postprocessor easier and more comfortable, disclosed embodiments include a dynamic user interface (UI) and flag capability. This allows postprocessor developers and internal software development to make certain functionality of one layer accessible and editable to a higher level.
Through this, software development enables postprocessor developers and authors to select certain types of transformations to be used and the original postprocessor developers and authors can allow the end user to customize the output NC program. This enables postprocessors developers and/or end users to adjust the CAM postprocessor in a very comfortable manner to their needs.
Other peripherals, such as local area network (LAN)/Wide Area Network/Wireless (e.g. WiFi) adapter 112, may also be connected to local system bus 106. Expansion bus interface 114 connects local system bus 106 to input/output (I/O) bus 116. I/O bus 116 is connected to keyboard/mouse adapter 118, disk controller 120, and I/O adapter 122. Disk controller 120 can be connected to a storage 126, which can be any suitable machine usable or machine readable storage medium, including but not limited to nonvolatile, hard-coded type mediums such as read only memories (ROMs) or erasable, electrically programmable read only memories (EEPROMs), magnetic tape storage, and user-recordable type mediums such as floppy disks, hard disk drives and compact disk read only memories (CD-ROMs) or digital versatile disks (DVDs), and other known optical, electrical, or magnetic storage devices.
Also connected to I/O bus 116 in the example shown is audio adapter 124, to which speakers (not shown) may be connected for playing sounds. Keyboard/mouse adapter 118 provides a connection for a pointing device (not shown), such as a mouse, trackball, trackpointer, touchscreen, etc.
Those of ordinary skill in the art will appreciate that the hardware depicted in
A data processing system in accordance with an embodiment of the present disclosure includes an operating system employing a graphical user interface. The operating system permits multiple display windows to be presented in the graphical user interface simultaneously, with each display window providing an interface to a different application or to a different instance of the same application. A cursor in the graphical user interface may be manipulated by a user through the pointing device. The position of the cursor may be changed and/or an event, such as clicking a mouse button, generated to actuate a desired response.
One of various commercial operating systems, such as a version of Microsoft Windows™, a product of Microsoft Corporation located in Redmond, Wash. may be employed if suitably modified. The operating system is modified or created in accordance with the present disclosure as described.
LAN/WAN/Wireless adapter 112 can be connected to a network 130 (not a part of data processing system 100), which can be any public or private data processing system network or combination of networks, as known to those of skill in the art, including the Internet. Data processing system 100 can communicate over network 130 with server system 140, which is also not part of data processing system 100, but can be implemented, for example, as a separate data processing system 100.
According to disclosed embodiments, a base level is the “library level” 202, containing basic functionality like file access (I/O functions) or mathematical functions (e.g. transformations) and can be shared across each and every individual postprocessor. Library level 202 can be supplied as a protected level to prevent it from being modified by postprocessor developers, and can be locked as illustrated by lock 220.
On top of the library level is the controller level 204, containing functionality specific to the machine tool controller, such as the Sinumerik automation systems from Siemens, the products of Dr. Johannes Heidenhain GmbH, the automation products of FANUC America, and others. Functions of the library level 202 can be overridden here, in some embodiments, but as this level can be supplied by software development and protected for the users and developers, this will only be rare cases. This level contains specific functions which are unique for a controller type, but they are not specific for a certain machine type.
Optionally, this is followed by the machine level 210 implementing functionality specific to a certain machine. This can be developed, for example, by advanced postprocessor developers or machine tool manufacturers and encrypted against reading through end users.
The kinematics structure of the machine tool model is implemented in the machine tool builder (MTB) layer 206. This can contain information such position, direction and other axis data, e.g. limits, dynamic properties, etc., and other data. This level can be derived from tools such as the NX CAM Machine Tool Builder by Siemens Product Lifecycle Management Software, Inc. (Plano, Tex.).
An original equipment manufacturer (OEM) level 208 can optionally be included. OEM level 208 is similar to the service layer 212 described below, but in this layer all OEM series specific code and settings are defined. Functionality that is the same for a given machine manufacturer can be abstracted here and be reused by sourcing this level.
The main level for adding customer specific functionality is the service layer 212, which can be developed by advanced postprocessor developers and can be protected against reading by end users.
The top level, in various embodiments, is the only level modifiable by end users and is referred to as the customer level 214. In that level, the end customer may adjust the postprocessor according to his needs. This is dependent on the settings of the postprocessor, which functionality is accessible to the user there.
Disclosed embodiments enable built-in support for sharing knowledge and effort. The layer concept allows the re-use of existing technology, protected against wanted and unwanted modifications and without the possibility to copy it illegally, but includes options to override implementations if necessary. This enables existing solutions to be shared with other partners.
Instead of having one monolithic postprocessor with all the functionality in it, disclosed embodiments can split the functionality into different layers that are interchangeable and protectable. This gives post developers a better way to reuse existing technology by reusing layers from various sources.
As discussed above, disclosed embodiments can contain multiple layers, each of which can append functionality to the level before. In various embodiments, the first and last layer are fixed (lib and customer), and there can be a flexible number of layers in between these.
In various embodiments, the layers can include:
For every property item in each layer, the postprocessor author may decide which type of license is necessary to see the value for the property or to do some modifications to it. This allows the developer of each layer to make flags available either to the developer of the next layer or even end customers. For example, a postprocessor author can allow the end user to modify a certain subset of the flags they created in the Service Level. Based on the license, the available flags can be made invisible, read only or read/write.
Configurable postprocessors as disclosed herein enable developers to easily adapt an existing postprocessor or even allow the end users to modify parts of the postprocessor, but only in the defined range which was allowed by the postprocessor developer.
Disclosed embodiments can use an automatic or semi-automatic approach with a self-generating user interface, based on a modified version of original libraries to emphasize to reusability and supportability of “off-the-shelf” post processor components.
It is possible to dynamically define the post processor UI. Each object 402, property 404, and their current value 406 can be made readable or writeable for the UI or completely suppressed by the postprocessor author. This includes objects and properties defined within each level whether it is provided by software development or postprocessor development. End users and less advanced post writers can easily configure the disclosed postprocessors or post configurator while advanced post writers have the full flexibility to introduce their own code and to programmatically make use of existing objects, properties and their access flags.
The following non-limiting code example adds a new object to the user interface:
Disclosed embodiments give developers means to customize the UI presented to their end customer. There are different object types that can be predefined and documented.
Access levels can be as follows:
where 0 indicates no access, 1 indicates read access, and 2 indicates read/write/full access.
For example:
In this example, an advanced user 604, such as a post processor developer, has advanced level access 614. This level of access, in this example, comes with an additional license, access to public properties, access to protected properties, no external TCL code or configuration files, and the ability to create custom TCL code and post processors.
In this example, a full-access user 606, such as an OEM or service user, has full level access 616. This level of access, in this example, comes with an additional license, access to public properties, access to protected properties, its own TCL editor, the ability to create custom TCL code and post processors, an encryption tool, the ability to execute plain TCL, and the ability add layers or modify the sourcing order.
According to various embodiments, the entire integration of the post configurator libraries with the CAM system can be designed and developed on top of the existing libraries. Disclosed embodiments can include clear separation of functionality on top of base layers: custom, service, machine, OEM, machine tool builder (MTB), as opposed to unstructured or monolithic postprocessors.
Various embodiments include extraction of kinematics and numerically-controlled (NC) related data from a machine tool model, and the dynamic UI disclosed herein. Access codes for objects and properties can be used for three or more different license levels.
The system can generate a machine tool post processor having a plurality of levels including a library level, a controller level, and at least one other level (705). The at least one other level can include one or more of a customer level, a service level, a machine level, an OEM level, and a machine tool builder (MTB) level. The plurality of levels can include at least one of a controller level or a library level. Each of the plurality of levels can be associated with an access level defined by properties of the levels.
The system can interact with a user in a dynamic user interface corresponding to the machine tool post processor (710). The dynamic user interface can selectively display the plurality of levels based on corresponding access levels. The dynamic user interface can be dynamically generated from the machine tool post processor. The dynamic user interface can include a plurality of objects, each with associated properties and values.
The system can store the machine tool post processor (715). This can include storing kinematics and NC data.
Of course, those of skill in the art will recognize that, unless specifically indicated or required by the sequence of operations, certain steps in the processes described above may be omitted, performed concurrently or sequentially, or performed in a different order.
Those skilled in the art will recognize that, for simplicity and clarity, the full structure and operation of all data processing systems suitable for use with the present disclosure is not being depicted or described herein. Instead, only so much of a data processing system as is unique to the present disclosure or necessary for an understanding of the present disclosure is depicted and described. The remainder of the construction and operation of data processing system 100 may conform to any of the various current implementations and practices known in the art.
It is important to note that while the disclosure includes a description in the context of a fully functional system, those skilled in the art will appreciate that at least portions of the mechanism of the present disclosure are capable of being distributed in the form of instructions contained within a machine-usable, computer-usable, or computer-readable medium in any of a variety of forms, and that the present disclosure applies equally regardless of the particular type of instruction or signal bearing medium or storage medium utilized to actually carry out the distribution. Examples of machine usable/readable or computer usable/readable mediums include: nonvolatile, hard-coded type mediums such as read only memories (ROMs) or erasable, electrically programmable read only memories (EEPROMs), and user-recordable type mediums such as floppy disks, hard disk drives and compact disk read only memories (CD-ROMs) or digital versatile disks (DVDs).
Although an exemplary embodiment of the present disclosure has been described in detail, those skilled in the art will understand that various changes, substitutions, variations, and improvements disclosed herein may be made without departing from the spirit and scope of the disclosure in its broadest form.
None of the description in the present application should be read as implying that any particular element, step, or function is an essential element which must be included in the claim scope: the scope of patented subject matter is defined only by the allowed claims. Moreover, none of these claims are intended to invoke 35 USC §112(f) unless the exact words “means for” are followed by a participle.
