A secondary distribution pulse calculator calculates, for each movement direction, secondary distribution pulses obtained by distributing the primary distribution pulses of each calculation cycle calculated by the primary distribution pulse calculator, before and after corresponding calculation cycles within ranges of distribution sections across the corresponding calculation cycles and having an acceleration-deceleration time constant of the corresponding movement direction as a section width, and then accumulating the primary distribution pulses for each calculation cycle. A drive controller drives at least one of a tool moving device and a work moving device on the basis of the secondary distribution pulses calculated by the secondary distribution pulse calculator unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Numerical control device for tool machine","description":"A numerical control device includes a primary distribution pulse calculator that calculates primary distribution pulses obtained by distributing movement amounts in first and second directions include","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8478439","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
