Problems solved by technology

[0003] However, in the process of S-curve acceleration and deceleration control, when the initial algorithm requirements change, it is necessary to prepare a special set of formulas for this special situation, and it is necessary to continuously develop new formulas to adapt to algorithm changes , and spend a lot of time testing
Making a change requires changing the equations in many places, the probability of missing or making mistakes is high, and making mistakes is not easy to understand and difficult to correct. It will also consume a lot of time for new algorithm engineers to understand so many formulas when handing over work

Abstract

The invention provides an S-shaped curve speed planning method, an S-shaped curve speed planning device, an S-shaped curve speed planning numerical control method and a numerical control machine tool. The S-shaped curve speed planning method comprises the following steps: acquiring the expected values of preset motion status parameters; acquiring a status function Mootionstatus(i) corresponding to the starting time point of a time period Ti; calculating a status function Motionstatus(i+1) according to the expected values of the preset motion status parameters and the status function Mootionstatus(i); and cyclically executing the steps to obtain status functions Mootionstatus(i) to Mootionstatus(8) corresponding to the time periods Ti to T7 so as to obtain data of S-shaped curve speed planning. According to the invention, after a recycled equation or method is packaged, only a packaged function, rather than all places where the equation is used, needs to be changed. Therefore, time is saved for programmers, and the system reliability is enhanced.

Description

technical field [0001] The invention relates to the technical field of acceleration and deceleration processing of numerical control machining, in particular to an S-curve speed planning method and device, a numerical control method and a numerical control machine tool. Background technique [0002] In the CNC system, in order to ensure that the machine tool does not produce impact, out of step, overtravel or vibration when it starts and stops or transitions between two curve segments, it is necessary to use a special acceleration and deceleration control algorithm to make the input of the motor change according to certain rules. , can be positioned quickly and accurately in various processing situations. In the prior art, in the S-shaped curve acceleration and deceleration control, the S-shaped curve is divided into seven time periods, and the time length of each time period is calculated according to the parameters such as the maximum acceleration of the system to complete...
