Numerical controller and numerical control program

A non-transitory storage medium which non-transitorily stores a numerical control program for controlling, in accordance with a machining program containing a plurality of command blocks that each specify a designated speed of a target, a machining device having a plurality of driving axes for driving the target, the numerical control program comprising:

• a synthetic speed calculation control unit configured to, for at least a curve block that designates a curve movement among the plurality of command blocks, calculate a synthetic speed that is revised so that the designated speed is initially accelerated from zero by a prior revision time constant and finally decelerated to zero by the prior revision time constant;
• a prior revision speed calculation control unit configured to calculate a prior revision speed of each driving axis for each time to realize the synthetic speed;
• a block identifying control unit configured to identify whether each of the command blocks is the curve block or a linear block that designates a linear movement;
• a reference speed calculation control unit configured to calculate, for each linear block, a reference speed of each driving axis for each time to realize the designated speed;
• a posterior revision speed calculation control unit configured to calculate a posterior revision speed that is revised so that the reference speed is initially accelerated from zero by a posterior revision time constant and finally decelerated to zero by the posterior revision time constant;
• and
• an output speed calculation control unit configured to calculate an output speed by adding the prior revision speed and the posterior revision speed.
