概要: The study deals with a development of an electric power chuck system for CNC lathe. Today, almost power chuck system for CNC lathes are used with hydraulic system included with hydraulic fluid which causes the environment pollution. Besides, not only the hydraulic pump always wastes energy, but also its heat transfer causes thermal deformation and deteriorates machining accuracy. In the study, in order to remove the hydraulic pump system from CNC lathe, the electric power chuck system which is able to adopt to the general CNC lathe and to have enough capability as general hydraulic power chuck system are developed. The electric power chuck system adopt to alternate general hydraulic pump system. From the experimental result, the developed electric power chuck system is found to have enough abilities. In addition, the electric power chuck system aims to improve machining accuracy by intercepting heat transfer and environmental pollution as well as removing the hydraulic system from machine tools. 続きを見る

概要: Many researches about cutting temperature have been reported, because of the great influence of a tool face temperature on a tool wear. However, there is few report about cutting heat. The cutting conditions (cutting speed, feed, etc.) and accuracy of temperature measurement in recent cutting are quite different from those in the past. In case of cutting a material like aluminum, for instance, the cutting speed is usually adopted as 1000m/min much higher than that in the past. The behavior of cutting heat (heat into chip, work and tool) in high speed cutting has been investigated applying theory and experiment methods in the present study. The heat generated in the cutting process is distributed to three parts such as main shear plane, rake face and clearance face. In this experiment, the work materials are AISI 1045 steeland Aluminum alloy A5052, and each cutting speed is up to 400m/min and 850m/min. The cutting heat are measured by accurate thermometers at different depths of cut and flank contact lengths. In addition, the heat ratio of chip, work and tool is calculated from theory. Experimental data are similar to theoretical results. Results of this research show that higher the cutting speed, higher the percentage of heat into the chip and lower the percentage of heat in the tool and work.

概要: (1) 生産性評価指数として有効送り速度比を導出し, 生産性の良否には, 位置決め制御系の時定数, 工具の1ブロック当たり平均移動距離, 工具移動ベクトルの向きの変化が影響を及ぼすことを示した. (2) 斜面加工で同じ加工精度を目標に, 同 じ半径方向の切込み条件で加工時間を比較すると, 斜面の勾配が0°または90°に近くない限り, スクウェアエンドミルよりもボールエンドミルを用いた方が生産性が良くなる.また, 工具径が大きいほどボールエンドミルがスクウェアエンドミルより効率的である. (3) 典型的な加工形状に対して, 生産性評価指数eを用いて工具経路パターンの違いによる生産性評価を行い, 等高線パターンによるeが, Zigzagパターンによるeよりも大きいことを示した. (4) 加工時間の比較でも, 一般に等高線パターンはZigzagパターンに比べて加工時間が短い.例外は, 波状スプライン面をZigzagパターンで波状に沿って加工する場合であった. (5) 等動力, 中高送りでの加工では, 一般に小径工具の方が加工時間が短い.例外は, 島があるポケット加工の場合であった. The productivity of machining centers is affected not only by the effective feed rates and average tool travel per block studied in the first report, but also by the generated tool paths, especially the variation of moving vectors of the tool. In this paper, first of all, the factor of productivity evaluation is defined extensively to the case of multi-F code, and furthermore expressed as a function of the time constants, feed, average travel per block and the moving vectors of the tool. The expression of the factor shows that the smaller the time constants and the average variation per block of moving vectors, the higher the productivity is, and the longer the average travel per block, the higher the productivity is. Then with feature-based work models, namely, spline plane, slope, boss, island and pocket, being exemplified, the productivity of those NC programs generated by I-DEAS CAM tool is analyzed by the self-developed NC program simulator in two patterns of tool paths, namely the contour line and zigzag. The results show that in most cases, the productivity of the tool path in contour line pattern is higher, and the productivity of machining with a tool of smaller diameter is higher when the cutting power is kept constant. The theoretic and simulative studies on the tool path will contribute to the development of new CAM tools. 続きを見る

概要: Instantaneous force with static deflection feedback model is applied to predict cutting force and dimensional surface error generation in peripheral milling with irregular tooth pitch end mills. It is demonstrated that the irregular tooth pitch end mill reduces the dimensional surface errors according to the chip regeneration mechanism. Unlike in case of uniform tooth pitch cutters, chip loads on each flute are different in milling with irregular tooth pitch cutters. The excess surface error generated by the flutes which have larger chip loads is removed by the following flutes which have smaller chip load due to the irregular tooth pitch. In order to predict precise cutting force and dimensional surface error for the irregular tooth pitch end mill, the chip regeneration mechanism or the static tool deflection has to be considered to derive the accurate chip loads. Predicted cutting force and dimensional sur face error show good agreement with experimental results. Up to 20% reduction in surface errors is achieved by using the irregular tooth pitch end mills tested. 続きを見る
