    摘要： The invention regards a method for co-ordinating and synchronizing the movement of servo-assisted axes in machines and apparatuses which execute various industrial applications. The method in object is applied in the programming of electronic control systems using specific commands collected in a particular table subdivided into sectors and known as a “CAM TABLE”, according to a programming technique known as “CAMMING”. The fundamental characteristic of the devised method is given by the fact that inside the aforementioned sectors of the CAM TABLE are described, through the use of a special operating code comprising a plurality of operating instructions, both the position relationships and the virtual laws of motion which bind a first reference axis known as the “MASTER axis”, and each of the other axes known as “SLAVE axes” together.

    摘要： A method for controlling an automatically operated lathe, provided with at least one spindle and at least one tool rest, includes the following steps. First, each of a plurality of transfer position data required in a sequence of machining programs in connection with at least one spindle and at least one tool rest is provided in a form of a cam-reference data directing a transfer position as a function of a cam rotation quantity. A plurality of pulse-train generating sources, each of which generates any pulse train, is also provided. Next, with regard to each of the plural transfer position data, a pulse-train generating source for generating a pulse train defining the cam rotation quantity as one component of the cam-reference data is designated, with the pulse-train generating source being selected from the plural pulse-train generating sources. Then, each of the plural transfer position data provided in the form of the cam-reference data is processed by using the pulse train generated through the pulse-train generating source as designated, so as to control a relative feed motion between at least one spindle and at least one tool rest in the sequence of machining programs.

    摘要： Every time the cumulative number of revolutions of a spindle rotating motor reaches a cumulative number of revolutions set in a data table, a CPU reads out, from a data memory section, moving positions of a workpiece and tool at the reached cumulative number of revolutions and the next cumulative number of revolutions, and a spindle rotational speed instruction value at the reached cumulative number of revolutions. The CPU sets the reached cumulative number of revolutions as a start point and the next cumulative number of revolutions as an end point, and divides the interval between the start and end points at predetermined timings. The CPU determines moving positions of the workpiece and tool at divided timings on the basis of the readout moving positions of the workpiece and tool. The CPU outputs the spindle rotational speed instruction value as a spindle rotational speed instruction signal to a reference spindle rotational speed setting circuit to control the rotational speed of the spindle rotating motor.

    摘要： Each time the number of cumulative rotations of a spindle rotating motor 11 reaches the number of cumulative rotations set in a position data table T, a CPU 22 reads out the mobile positions of a work piece and tool at thus reached number of cumulative rotations and the next number of cumulative rotations to reach from a position data storage section 25, and reads out a moving speed characteristic between the reached number of cumulative rotations and the next number of cumulative rotations to reach from a moving speed characteristic storage section 27 according to an auxiliary operation designation in the position data table T. Thereafter, assuming the reached number of cumulative rotations to be a start point and the next number of cumulative rotations to reach to be an end point, the CPU 22 divides the part between the start and end points into predetermined timings, and defines the mobile positions of the workpiece and tool at each of the divided timings according to the read-out mobile positions of the workpiece and tool and moving speed characteristic.

    摘要： A numeric array of move command data Qi constituting a reference cam diagram F (.theta.) is stored in advance in a data table of a CMOS memory. Alternatively, a shift position of a cam corresponding to a rotational angle .theta. of the cam is stored in advance so that move command data can be generated by obtaining the shift position of the cam from the rotational angle of the cam based on the rotational angle value. In response to the input of a shift Ka in the lift direction, shift Kb in the pitch-circle direction, maximum lift Kc, and data number n as a criterion for extension or compression in the pitch-circle direction, the move command data can be corrected by automatic processing by means of a motion controller. Thus, final move command data Pk can be generated and outputted as position commands.

    摘要： It is possible to easily change CAM tables, which are used for executing an electronic CAM operation. A CAM computation program performs an electronic CAM operation, using a CAM table that is an array in which displacements of a slave axis of an electronic CAM are associated with phases of a master axis of the electronic CAM. A CAM table generating program receives input of a CAM definition variable that defines an electronic CAM operation to be realized by a motion control, and generates a CAM table in which a CAM curve is stored as an array corresponding to the inputted CAM definition variable. A microprocessor performs a CAM computation program using the CAM table. If the microprocessor receives the input of the CAM definition variable, the microprocessor performs the CAM table generating program to generate the CAM table, and stores the generated CAM table into the main memory.
