Abstract

Production equipment, e.g. a lathe, has a numerical control system acting upon drives for a tool for forming or machining a part to a desired shape or profile. A part programming apparatus comprising a visual display 10 and selector keys 12-18 for selecting predetermined basic shapes (for example those shown on the keys) and displaying these in selected juxtaposition to each other on the visual display (for example 12', 14', 16', 15', 13', 12' as shown on display 10). The operator may then assign numerical co-ordinates to selected points e.g. P1 - P7 of the displayed image for writing this data into the program. <IMAGE>

Description

SPECIFICATION Prt rt pragramming for production equipment This invention relates to part programming for production equipment such as machining equip ment and especially lathes.
It is known to provide machining equipment such as lathes with a numerical control system, which system may be programmed according to the shape or profile of a part to be produced, and which can then be used to control drives ofthe equipment such that the part will be produced appropriately to that shape or profile. An important aspect is the formulation of the program, or part program, and hitherto available apparatus have not been wholly straightforward for the operator to use.
In accordance with this invention, there is pro ,vided a part programming apparatus, comprising a visual display, and selector key means for selecting predetermined basic shapes and displaying these in selected juxtaposition to each other on the visual display. In an embodiment to be described, the apparatus includes means for the operator to assign numerical co-ordinates to selected points of the displayed image and means whereby the image will be re-displayed to corresponding scale. Means may also be provided for writing, into the program, scan ning cycles for controlling movements of the machine tools. The program may be produced in any required form, whether tape or otherwise, and in any required code.The part programming apparatus may be associated directly with production equip menu to be controlled by the program, in which case it may display the actual shape of the part during formation of that part, or the apparatus may stand alone and serve simply for the formulation of the program.
The above-mentioned embodiment of this invention will now be described, by way of example only, with reference to the accompanying drawing, which is a diagrammatic view of a visual display and selector key means of the embodiment of part program ming apparatus.
The apparatus shown is intended for formulating a program in respect of a part to be turned on a lathe.
It comprises a visual display 10 and selector keys 12-18. Key 12 is operable to set up a cylindrical shape (e.g. 12') on the display, key 13 is operable to set up a conical shape (cone decreasing-e.g. 13'), key 14 a conical shape (cone increasing-14'), and keys 15-18 are each operable to set up respective curved sec tions (e.g. 15', 16') on the display. Any desired part profile can be approximately set-upon the display by selection of the appropriate ones of keys 12-18, and further keys 20,22 are selectively operable for building up the image from the left or the right. As each successive section of the image is built on to the existing image, the control system of the apparatus operates automatically to reduce the scale of the displayed image.
Once the image has been formulated in the above manner, the operator may key-in the numerical coordinates required for principal points of the profile (e.g. P1,P2...) and the arrangement is such that the assigned co-ordinates appear as a listing at 24 on the display. Once this co-ordinate-assignment is complete, a further key may be operated whereupon the image re-appears to the relative scales dictated by ihe assigned co-ordinates.
As mentioned previously, the apparatus may be arranged to write, into the program, scanning cycles for the lathe tool. Moreover, the program may be such that the lathe tool will automatically turn the partto its final required profile, orthe program may include a limit profile spaced slightly from the final required profile, enabling operation according to my patent application 81.03501.
1. In orfor production equipment, a part programming apparatusforforming a program according to the shape or profile of a part to be formed for a numerical control system to use that program in the control of drives of the equipment for forming a part to the desired shape or profile, said part programming apparatus comprising a visual display and selector key means for selecting predetermined basic shapes and displaying these in selected juxtaposition to each other on the visual display.
2. A part programming apparatus as claimed in claim 1, including means for the operator to assign numerical co-ordinates to selected points of the displayed image and writing this data into the program.
3. A part programming apparatus as clamed in claim 2, arranged to re-display the image scaled according to the assigned co-ordinates.
4. A part programming apparatus as claimed in any preceding claim, arranged to write instructions into the program as to required movements of a forming tool of said equipment.
5. A part programming apparatus as claimed in any preceding claim, arranged to respond to each successive said basic shape being selected to display the image (including that newly selected shape) at a scale correspondingly reduced relative to that of the image displayed immediately beforehand.
6. A part programming apparatus as claimed in any preceding claim, arranged to display the actual shape of a part during a machining operation, from the program data.
7. A part programming apparatus as claimed in any preceding claim, arranged to write data into the program defining a limit profile effective to provide an override limit on the permitted manual movement of a forming tool of the equipment.
8. A part programming apparatus in or for a lathe and substantially as herein described with reference to the accompanying drawings.
