NC software 24 comprises several programs, is used for the program 42 of motion of program 40, axle of control assembly processing and the program 44 that shows for the operator, and provides such as the program that data etc. are set of controlling motion of main shaft, timer, mathematical function and lathe.Lathe among Fig. 3 is provided with data (MSD) file 46 and has accurately listed some more so accurate lathe property data of using for system with formula, for example the instruction of rate of feed, storage circulation and part program.In addition, according to the present invention, six color assignment of the display mode information that occurs with literal and/or diagram form on CRT18 are also included within the MSD file 46.

With regard to the structure of file, control system is to recognize these files by the form of " file name ".Start three characters and marked the storer of storing this document, have the file name of six characters and the knowledge of one to three character not to mark Chi with heel.For example a typical file name can be MB2:MSGTXT.There is a character type information in the magnetic bubble memory No.2 in this example representative.

Lathe is provided with data (MSD) source file and comprises one group of independent record that sequences order; The length of each record can reach 80 characters.MSD records the statement form of making an appointment, and it has five master data compositions or data fields, i.e. MSD form identifier, MSD form index, access code identifier, parameter value and note.This MSD record is grouped into seven kinds of forms, shown in the table I.In addition, every kind of triliteral form identifier of form.

(the table I vides infra)

The table I
	Form types form identifier
1. desired data table RQD 2. axle Table A XS 3. integer table INT 4. floating-point table FLP 5. boolean show BLN 6. alphabet CHR 7. storage circular list CYC

In this form, the position of parameter is stipulated by index.Index is the entry position in the form that is identified.Index, promptly the position in the form is to discern with the specific function that will carry out.How the regulation of this function promptly carries out this function, is decided by the data type and the parameter value at place, form entry position.This access code provides the access protection level of appointment simply to record, to prevent from it is made the change of Non-Patent.The form parameter is five kinds of a kind of in dissimilar always, and these five kinds of data types are: (a) floating type-" floating-point " decimal value; (b) round values of mixed decimal point of integer type-not; (c) Boolean type-Zhen (T) or false (F) value; (d) the ASCII letter or the hyphen of alpha type-any lexicographic order; And (e) enumerate type-some parameter and have the value of specific names, typical as " adding ", " subtracting ", " linearity " or " rotation " etc.Note is selected for use, but when adopting it, note contains some significant data components in the MSD record, is usually included in the bracket, with data be what to be separated.

Referring now to Fig. 4,, for example a MSD file can be produced by system designer, he is input to the CNC system to a series of MSD records 48 by the keyboard 20 of numerical control platform 12, be input to common file editor 50 at there MSD record, they are transformed into the MSD source file and deposit in the storer 52 at edit routine 50, and this storer for example can be a magnetic bubble memory.The manufacturing plant of CNC can provide complete MSD file in the storer, and this file can intactly use.On the other hand, user (for example operator) also can utilize the MSD edit routine that separates shown in Figure 6 to revise this MSD file.

Suppose that after system's energising on its position, as shown in Figure 5, NC software 24 asks to carry out MCL program 28 to CNC software at first repeatedly.Whenever, be called run-down, and comprise MCL program 32 of " calling " fixing MCL program 30 and customization through a MCL program 28.Time cycle between each MCL scanning is decided by that the current treatment state of system and CNC receive situation about taking place the input from lathe 10 by MCL window 26.Depend mainly on required system the sweep time of CNC software inhouse.When in case the input that comes from lathe changes or when one of mark of MCL window 26 changes, the scanning of a MCL takes place just.In addition, if spent a period of time behind a MCL end of scan, then a new MCL scanning promptly begins.In other words, the MCL program is moved by the minimum speed limit that presets, if but the activity of lathe 10 quickening, program is also accelerated operation.

After being provided with above-mentioned working environment, can consider details of the present invention now.What the present invention was concerned about is the demonstration of information on CRT18 and the improvement of display color, particularly the machine operation person can on-the-fly modify (originally lacking) color allocation of setting up in advance, and utilizes " window calls " of 26 pairs of NC softwares 24 of MCL window to carry out on-the-fly modifying of color under the control of MCL program 28.

Referring to Fig. 6, contain MSD source file 54 that lathe is provided with data recording by the MSD handling procedure, at first be used to compile out a MSD binary file 56.This handling procedure is a conversion program that simply source code is become binary code.Scale-of-two MSD file 56 is that system operation is needed.Also comprise an interactively MSD edit routine 58 in the system, make the lathe user revise this scale-of-two MSD file 56 by input equipment 60 as required, input equipment 60 can comprise the keyboard 20 of Machine-Tool Control platform 12.According to the present invention, there are eight kinds to enroll color in the source file 54, and are positioned at above-mentioned integer form with MSD record format.These are recorded among Fig. 6 and mark with sequence number 62, and it comprises following classification: backcolor, counter-rotating video color, form (constant data) character color, data character color, the mistake and/or the color of reporting to the police, need the color that the operator replys and the color of " critical event ".Can give a classification according to following rule by any color in black, blue, green, blue or green, red, pink, amber and the eight kinds of colors that white is formed: (1) reverses video color can be identical with backcolor, but other are all kinds of all can not to have same color with backcolor, and (2) this counter-rotating video color must be different with data color.

In order to understand the relation between background, data and the counter-rotating video color, now do following explanation.When under normal circumstances showing alphanumeric, the grid at character place is a backcolor, and character is a data color.On the other hand, when character showed with the counter-rotating video color, the grid at character place was a data color, and character is the counter-rotating video color.Therefore, if backcolor is defined as black, data color is redness for the green video color that reverses, then character shows green word usually on black background.But during the counter-rotating video color, character will show The Scarlet Letter on green background.

In addition, for backcolor, counter-rotating video color, data color and critical event color, the distribution of an original color that lacks can be stipulated or pre-determine, the current original data color that lacks that is showing or " release " a kind of new color can be selected to overwhelm and format color, mistake and warning color and operator reply color.Cross after this, this original data color that lacks still can recover i.e. " rebound " to the original color that distributes.

As shown in Figure 6, the operator utilizes MSD edit routine 58 can change the color allocation of enrolling in the past in MSD source file 54.The operator can revise or change the distribution of color and the definition of original missing colors as required.In addition, the operator after 58 pairs of MSD color allocation of edit routine are made any modification, just has a handling procedure the display control program 62 of scale-of-two MSD assignment transfer to Fig. 7 by the MSDEDIT program.The display routine 64 of the NC software 24 that has kept then, produces literal and figure by known way on the CRT18 of numerical control platform 12.The production method of figure in above-mentioned relevant Application No. No._ (case number 21-NU-3402) open.

In addition, for example when MCL program 28 detects operating mistake or alert if, the present invention also provides and this is reacted and revises the method for background and data color, can cause the attention of operator to error situation like this, so that take adequate measures.As shown in Figure 7, MCL program 28 comprises two subroutines 66 and 68, and these two subroutines contain the routine in the MCL32 that is present in customization, are used for the display control program 62 of NC software 24 is done the window request, so that change backcolor and data color respectively.In this case, new color in fact is pulled to above the last color, and character is new color.When condition no longer existed, color originally can also its original state of rebound, showed with the colour that recovers former figure that pre-exists and literal.

The appendix I has comprised that is realized a colored program listing, and the appendix II is illustrated as the colour that improves relevant spindle of numerical control lathe rotating speed and shows the required program of writing out with the PCL language.Figure wherein is a bar chart, and the speed of mainshaft is expressed as the percentage of maximum (top) speed, and allows certain hypervelocity.Under the normal condition, the background of CRT is black and can comprises some written material.A blue look straight line is arranged, and its length is represented the maximum (top) speed of main shaft.When the speed of mainshaft is zero, so this straight line is blue entirely.When rotating speed increases by zero, represent that part of lines growth of actual speed and represent with cyan.When rotating speed continue to increase, the cyan of lines part was in growth and blue color part is shortening.This appearance is picture simulation colour band meter a bit.When in a single day rotating speed reaches controlling value or desirable value, represent that part of (cyan) of true rotating speed just changes green into.Under the overspeed situation, that part of lines of expression rotating speed can become pink and background CRT can become redness.So that cause operator's attention at once.

Therefore, more than show and narration be to make CNC software that several display modes are set up the ways and means of specific color, these display modes can be revised dynamically by the process equipment manufacturing plant of system or system user or with the MCL logic software again.

And the preferred embodiments of the invention of just considering at present of showing here and illustrating to those skilled in the art, can be done some modifications to this at once.Therefore, we do not wish that this part invention is only limited to this specific embodiment of showing and describing, and plan to comprise that all fall into by various modifications, replacement and variation in the defined the spirit and scope of the present invention of claims.
