摘要： PURPOSE:To securely retreat tool to a position for tool change without generating interference with a work even when any type of the work is executed by storing an executed tool moving command as a custom macro-variable per block in plural numbers and setting a retreating sequence based on those commands. CONSTITUTION:When the operating command of one block is outputted from a data memory 15 and the operation of the command is completed, a tool present position A is transferred from a machine tool 18 side to a prescribed system variable area R of a RAM16. Namely, the tool position to correspond to the respective block ends of a program is successively stored in the RAM16 as information for the retreating of the tool. After that, when a tool change command is generated or the damage of the tool is generated and an alarm is generated from the machine tool 18, the moving of the tool is stopped and this macro-program is executed as the program to specify the retreating sequence by the data of the accessable system variable area R. Thus, a retreating route can be always determined freely as the optimum route.

摘要： PURPOSE:To efficiently carry out the editing of programs by providing the step for changing the working speed after the working order, etc. on each tool rest are determined and the step for setting again the working order. CONSTITUTION:In Step 1, the shapes of material and parts are inputted in dialogue form by using symbolic keys, and in Step 2, a working process is defined by calling out the picture of the working definition. Then in Step 3, the editing of the working process such as editing of S-code is executed. In Steps 4, all the NC programs are prepared, and registered into an NC memory. In Step 5, the program check such as tool interference check is carried out by selecting the picture moving functions, and in step 6, it is examined if a trouble exists in the machining by the prepared program or not. If an alarm operates in this time, the editing for the process is carried out again in Step 3.

摘要： PURPOSE:To check an interference and enable a selection of the most suitable tool, by drawing a tool configuration as well as a raw material configuration and a machining configuration in a tool selection by a tool file when an NC command data is created by use of an automatic schedule determining function. CONSTITUTION:An NC equipment comprises a CPU 1, a data input/output unit 3, a program memory 5, a data memory 6 for storing tool data and the like, and a control unit 8 for controlling drive axes of a machine tool 7. In an automatic programming, first a coordinate system is selected, then a raw material configuration is entered, a machining configuration and dimensions are entered, and then a tool is selected. In an example of a drawn cutting tool, when a parameter l as well as a cutting edge angle alpha, a lip angle beta and a mounting angle gamma are designated when the cutting edge is set to an origin of coordinates, a tool configuration as well as a raw material configuration and a machining configuration are automatically drawn, whereby an operator can find out an interference of a designated tool and the like readily.

摘要： PURPOSE:To simultaneously command scaling and mirror image with the same block by changing the command position to a position symmetrical to the position for a positive scale magnification in case of a negative scale magnification. CONSTITUTION:An NC device main body 1 refers to parameters stored in a non-volatile memory 1d through a CPU 10 to execute the program in a ROM 1b and performs scaling to expand or reduce a designated shape with a scaling center as the center in accordance with designation of the scaling center and the scale magnification. In this case, when the scale magnification designated from a keyboard 1e is negative, the designated shape is subjected to scaling so that it is symmetrical to the shape subjected to scaling for a positive scale magnification, and scaling and mirror image are simultaneously commanded with the same block to not only facilitate programming but also shorten an NC tape.

摘要： PURPOSE:To enable machining data to be correctly created, by calling the optimum file from a file classified by the material quality registering plural cutting condition data in accordance with the material quality of a work and determining a cutting condition by the material quality and a machining process. CONSTITUTION:If a machining data is input from a data input device 3 in accordance with a machining program commanding a fixed machining process to a machine 6, an NC unit prepares plural cutting data in accordance with the material quality from a file classified by the material quality stored in a memory 5. Next the unit, assigning a machining kind and deciding a machining process from data containing shape, accuracy and roughness of a finishing surface of said machining kind, selects a file of the optimum cutting condition from the prepared cutting condition data. Machining data created on the basis of this cutting condition file can be confirmed as necessary by a display device 4 of CRT or the like. In this way, a machining command is given from the NC unit to the machine 6.

摘要： PURPOSE:To fix the rotational speed of a spindle by measuring and storing the instantaneous variation value of the rotational speed of the spindle and adding a correction command value to the speed command value of the spindle. CONSTITUTION:A position coder 5 generates pulses in proportion to the rotation of a spindle motor 3. In a numerical controller 10, a synchronizing pulse generating means 111 converts the pulse string into a prescribed value to drive a motor 44 through a servo amplifier 34 and a speed variation correcting means 112 detects the rotational speed of the spindle 3, finds out a variation value, operates a correction value DELTAS, and stores the value DELTAS in a memory 114 and an adder 113 adds the value DELTAS to a practical speed command S. Consequently, the rotational speed of the spindle motor 53 is fixed, the rotational speed of the spindle 3 is accurately synchronized with that of the C-axis 8 of a work 1 and highly accurate hob working can be attained.

摘要： PURPOSE:To enable a user to easily produce the high-speed distribution data which controls a tool machine as necessary, by producing previously the execution type data needed for a specific function like a read working, etc., by the custom macro. CONSTITUTION:The execution type data is divided into two parts for cycles 1 and 2. In a read working process a header HDR is selected out of an area for cycle 2 by a designated data number dp2. Said execution type data is previously the custom macro based on the data set by an operator. Thus it is possible to perform the read working with high accuracy during the high-speed revolutions of a work by changing the distributing cycle of the working data in accordance with the designated bit value of the data type contained in the header HDR.

摘要： PURPOSE:To attain protection of the program secrecy and at the same time to quickly execute a numerical control NC program, by converting the numerical control program written in a high standard language into machine words by a compiler to store them in a ROM cassette. CONSTITUTION:At the outset, the contents of an NC program written in a high standard language like FAPT, etc., and stored in a storage medium are converted into such a format that can be easily carried out by a numerical controller by means of a compiler attached externally to the numerical control ler. The converted contents of the NC program are stored temporarily in a RAM12 and then read out to be written to a ROM in a ROM cassette 18 by a ROM writer. Then the cassette 18 is connected the numerical controller as shown by a dotted line and the contents of the cassette 18 are read out and stored in the RAM12. Then an NC action is carried out according to the NC program stored in the RAM12.
