以下、図面を参照して、本開示の第1実施形態に係る数値制御システムについて説明する。
第1の優先度算出アルゴリズムの下では、優先度算出部54bは、位置姿勢算出部35から送信される各制御軸の軸移動量に基づいて複数のチェック対象組に対する優先度を算出する。より具体的には、優先度算出部54bは、軸移動量が大きい制御軸から降順で、各制御軸と機械要素-制御軸紐付け情報によって関連付けられる各機械要素に対する機械要素順位を算出する。次に優先度算出部54bは、算出した機械要素順位が高い機械要素から降順で、各機械要素を含むチェック対象組に対する優先度を算出する。すなわち第1の優先度算出アルゴリズムの下では、優先度算出部54bは、単位時間当たりの軸移動量が大きな制御軸と関連付けられている機械要素を含むチェック対象組において干渉する可能性が高いと判断し、このような機械要素を含むチェック対象組の優先度を高くする。
第2の優先度算出アルゴリズムの下では、優先度算出部54bは、位置姿勢算出部35から送信される各制御軸の軸移動量ベクトルに基づいて複数のチェック対象組に対する優先度を算出する。より具体的には、優先度算出部54bは、制御軸毎に算出された軸移動量ベクトルを用いることによって、複数の制御軸のうち2つを組み合わせて構成される軸対に対する相対軸移動量ベクトルを算出する。ここで制御軸の総数がMである場合、軸対の総数はM(M-1)/2である。また例えば第n制御軸の軸移動量ベクトルをvnとし、第m制御軸の軸移動量ベクトルをvmとした場合、第n制御軸及び第m制御軸によって構成される軸対に対する相対軸移動量ベクトルdnmは、vn-vmとなる。
第3の優先度算出アルゴリズムの下では、優先度算出部54bは、位置姿勢算出部35から送信される各制御軸の軸移動量ベクトル及び各機械要素の移動前位置ベクトルに基づいて複数のチェック対象組に対する優先度を算出する。より具体的には、優先度算出部54bは、各制御軸の軸移動量ベクトルと、各機械要素の移動前位置ベクトルと、機械要素-制御軸紐付け情報と、に基づいて、各チェック対象組を構成する2つの機械要素の間の距離の減少率に比例する減少率パラメータを算出し、これら減少率パラメータに基づいて各チェック対象組に対する優先度を算出する。
チェック対象組抽出部54aは、数値制御装置3における移動パルスと、工作機械2における各制御軸と複数の機械要素のうちこの制御軸に沿って移動する機械要素とを関連付ける機械要素-制御軸紐付け情報と、工作機械2における各制御軸の間の従属関係を規定する各軸従属関係情報と、に基づいて、工作機械2を構成する複数の機械要素の全ての組み合わせの中から1組以上のチェック対象組を抽出する。これにより、複数の機械要素の全ての組み合わせの中から、干渉しないことが自明な機械要素の組み合わせ(例えば、移動パルスに基づく制御軸に沿って一緒に移動する機械要素の組み合わせ)を除いてチェック対象組を抽出することができる。また数値制御装置3は、移動パルスに基づいて複数の機械要素を複数の制御軸に沿って移動させるとともに、チェック対象組抽出部54aによって抽出されたチェック対象組について干渉チェック演算を行う。本実施形態によれば、干渉チェック演算を行うチェック対象組を、干渉しないことが非自明な機械要素の組み合わせのみに絞り込むことができるので、数値制御装置3における干渉チェック演算を全ての組み合わせについて行う場合よりも短時間で終えることができる。
