In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0020] Figure 1 This is a flowchart illustrating a lathe machining control method in one embodiment.

[0021] In this embodiment, as Figure 1 As shown, the lathe machining control method includes steps 102 to 106.

[0022] Step 102: Acquire the digital signals of the handwheel pulses during multiple operating control cycles of the lathe.

[0023] The handwheel pulse digital signal can be a two-phase digital signal of the lathe handwheel pulse. The handwheel pulse digital signal includes the handwheel pulse A-phase digital signal and the handwheel pulse B-phase digital signal.

[0024] The scenario for obtaining the handwheel pulse digital signal within multiple operating control cycles of a lathe includes: using an unsigned integer counter with a certain value range to perform preliminary detection on the pulse input signal of the handwheel installed on the lathe, so as to obtain the handwheel pulse digital signal within multiple operating control cycles of the lathe.

[0025] Step 104: Determine the number of handwheel pulses within multiple operating control cycles of the lathe based on the handwheel pulse digital signal.

[0026] The handwheel pulse count can be the number of pulses obtained by counting the handwheel pulse digital signal based on the 16-bit unsigned integer counting rule.

[0027] Determining the number of handwheel pulses within multiple operating control cycles of a lathe based on the handwheel pulse digital signal includes: obtaining the pulse counting cycle boundary value of the lathe; and determining the number of handwheel pulses within multiple operating control cycles of the lathe based on the pulse digital signal and the pulse counting cycle boundary value.

[0028] The pulse counting cycle boundary value can be a value that allows adjustment of the pulse counting cycle direction of an unsigned integer counter. The pulse counting cycle boundary value can also be a boundary value within the range of values ​​that the unsigned integer counter can take.

[0029] Step 106: Determine the handwheel machining control command for the lathe based on the number of handwheel pulses within multiple operating control cycles.

[0030] Handwheel machining control commands can be formed based on the number of handwheel pulses within multiple operating control cycles, and can control the machining progress of the workpiece.

[0031] The lathe machining control method provided in this embodiment determines the number of handwheel pulses that reflect the changes in the input signal of the handwheel pulse generator based on the handwheel pulse digital signals within multiple operating control cycles of the lathe during workpiece machining. Based on the obtained handwheel pulse counts from multiple operating control cycles, the lathe handwheel machining control command for controlling the workpiece machining progress is determined. This method enables precise control of the workpiece machining progress, effectively improving the problem of large deviations in the pulse generator used to control the workpiece machining progress caused by manual operation of the lathe handwheel. It can improve machining control efficiency while ensuring machining control accuracy, thereby meeting higher requirements for CNC machining effects.

[0032] Figure 2 This is a schematic diagram of the specific process of step 106 in one embodiment.

[0033] In this embodiment, as Figure 2 As shown, step 106 includes sub-steps 202 to 206.

[0034] Step 202: Obtain the magnification constraint coefficient of the lathe.

[0035] The magnification constraint coefficient can be the range of magnification values ​​allowed during the machining of a workpiece on a lathe. The magnification constraint coefficient can be between 0 and 2.

[0036] Step 204: Determine the handwheel machining magnification value of the lathe based on the number of handwheel pulses and the magnification constraint coefficient within multiple operating control cycles.

[0037] The following scenarios determine the lathe's handwheel machining magnification value based on the number of handwheel pulses and magnification constraint coefficients within multiple operating control cycles: obtaining the lathe's pulse accumulation time window and operating control cycle duration; determining the number of pulse accumulation cycles based on the pulse accumulation time window and operating control cycle duration; and determining the lathe's handwheel machining magnification value based on the number of handwheel pulses, pulse accumulation cycles, and magnification constraint coefficients within multiple operating control cycles.

[0038] The pulse accumulation time window can be the time span set to generate a smooth, stable, and satisfactory pulse signal during normal continuous rotation of the handwheel. The operation control cycle duration can be the operation cycle of the control signal during workpiece processing. The pulse accumulation cycle count can be the number of operation control cycles between a single pulse signal input.

[0039] It should be noted that in CNC systems with short operating control cycles, due to the high refresh rate of the data signal, the pulse input frequency when rotating the handwheel pulse generator is much lower than the operating data refresh rate. For example, when the operating control cycle is 1ms, in practice, it may take 3 to 5 operating control cycles to record a single pulse signal input to form a smooth, stable, and ergonomic operating control signal.

[0040] Step 206: Determine the lathe's handwheel machining control command based on the handwheel machining magnification value and the number of handwheel pulses within multiple operating control cycles.

[0041] The scenarios for determining the lathe's handwheel machining control command based on the handwheel machining magnification value and the number of handwheel pulses within multiple operating control cycles include: determining the pulse accumulation direction within the pulse accumulation time window based on the number of handwheel pulses within multiple operating control cycles; and determining the lathe's handwheel machining control command based on the pulse accumulation direction and the handwheel machining magnification value.

[0042] Figure 3 This is a schematic diagram of the specific process of step 106 in one embodiment.

[0043] In this embodiment, as Figure 3 As shown, step 106 includes sub-steps 302 to 304.

[0044] Step 302: Determine the cumulative number of pulses within the pulse accumulation time window based on the number of handwheel pulses and the pulse accumulation time window within multiple operating control cycles.

[0045] The scenarios for determining the cumulative number of pulses within a pulse accumulation time window based on the number of handwheel pulses and the pulse accumulation time window within multiple operating control cycles include: determining the number of handwheel pulses within the first and last operating control cycles based on the number of handwheel pulses and the pulse accumulation time window within multiple operating control cycles; and determining the cumulative number of pulses within a pulse accumulation time window based on the number of handwheel pulses within the first and last operating control cycles.

[0046] Based on the handwheel pulse count and pulse accumulation time window within multiple operating control cycles, the following scenarios determine the handwheel pulse count within the first and last operating control cycles: The handwheel pulse count is... And denote its positive or negative sign as This indicates the direction of handwheel rotation, which is also the direction of pulse accumulation in the pulse generator.

[0047] Starting from the first cycle, until the... Between cycles, the cumulative number of pulses within the pulse accumulation time window is determined based on the number of handwheel pulses during the first and last operating control cycles, as follows:

[0048] In the formula, Indicates the duration of the operation control cycle. This indicates the pulse accumulation time window.

[0049] Step 304: Determine the handwheel machining magnification value of the lathe based on the cumulative pulse count, cumulative pulse cycle count, and magnification constraint coefficient.

[0050] Based on the number of handwheel pulses, the cumulative number of pulse cycles, and the magnification constraint coefficient within multiple operating control cycles, the following is the case where the handwheel machining magnification value of the lathe is determined:

[0051] In the formula, Indicates the cumulative number of pulse cycles. Indicates the number of handwheel pulses. This represents the ratio constraint coefficient.

[0052] During lathe workpiece machining, if the pulse and handwheel rotation directions are inconsistent, the handwheel stops rotating, the handwheel machining magnification value becomes 0, and the machine switches to pause mode; if the lathe handwheel machining magnification value is non-zero and the pulse accumulation direction of the pulse generator is... When the handwheel is in a positive position, automatic machining is initiated and the workpiece is machined according to the handwheel machining magnification value. If the handwheel machining magnification value changes to another positive value during the process, machining continues according to the updated handwheel machining magnification value. If the handwheel reverses direction during the process, the pulse accumulation direction of the pulse generator changes. If the value is negative, pause the process and then start the retraction machining by adjusting the machining magnification value of the handwheel converted by the pulse count.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
