Basic functional principles of machine tool operations Machine Tools produce desired geometrical surfaces on solid bodies (preformed blanks) and for that they are basically comprised of; • Devices for firmly holding the tool and work • Drives for providing power and motions to the tool and work • Kinematic system to transmit motion and power from the sources to the tool-work • Automation and control systems • Structural body to support and accommodate those systems with sufficient strength and rigidity. For material removal by machining, the work and the tool need relative movements and those motions and required power are derived from the power source(s) and transmitted through the kinematic system(s) comprised of a number and type of mechanisms. (i) Concept of Generatrix and Directrix • Generation of flat surface The principle is shown in Fig. 2.1 where on a flat plain a straight line called Generatrix (G) is traversed in a perpendicular direction called Directrix (D) resulting a flat surface. • Generation of cylindrical surfaces The principles of production of various cylindrical surfaces (of revolution) are shown in Fig.

  • Validation of Thermal Errors Compensation Models for Different Machine Tool Structures Via Test Pieces
    Validation of thermal errors compensation models for different machine tool structures via test pieces Otakar Horejš, Martin Mareš, Lukáš Havlík 1. Introduction 3. Six-spindle automatic lathe Although real-time software compensations of thermal errors exist, The test pieces can be also employed for the evaluation of the majority of these models are not sufficiently validated in real machine tool thermal errors. This application is illustrated on a six- finishing operations using a test piece. The accuracy and spindle automatic lathe. The basic scheme of the test piece, robustness of the developed models are mostly examined using manufactured by a specific technology, is depicted in Figure below. non-cutting measurements. In contrast, machining tests can be more intuitively understood to evaluate the machine’s accuracy for typical machine tool users. Moreover, the machined test piece represents a suitable method to verify thoroughly the industrial applicability of the developed thermal errors compensation model for machine tool builders. The paper presents the authors’ recent research on these issues. Specific test pieces for different machine tool structures are illustrated (test pieces for a gantry-type 5-axis milling centre with a rotary table, a six-spindle automatic lathe and a vertical turning lathe). 2.

  • M32 Sliding Headstock Type CNC Automatic Lathe
    M32 Sliding Headstock Type CNC Automatic Lathe M32-VIII Ultimate Gang + Turret: The M32 is Reborn While inheriting the basic configuration of “gang tool post + turret”, the new M32 has pursued the optimal balance of strength and weight through structural analysis, and greatly improves the rigidity that is the cornerstone of machining. In addition, a single drive mechanism is introduced for rotary tools on the turret tool post, together with updated tooling. The rotary tool drive motor on each tool post has also been enhanced. 5.5/7.5 kW high-power spindle motors are adopted for both front and back spindles, achieving powerful machining and high acceleration/deceleration. The gang tool post features a B-axis spindle (Type VIII) that supports contouring through 5-axis control. The back tool post is equipped with an adjustable angular spindle (Type VII/VIII) for more complex machining in combination with the Y axis. Enhanced back machining capability is also increased due to the flexibilty of the machining process. In addition, a 38mm oversized specification option is available, and it is possible to switch between guide bush and guide bushless operation. 4 M32 Citizen Basic Structure The image shows the type VIII Rear tool post X1 Type V: 5 stations Main spindle Type VII: Max. of 9 stations (including 3 adjustable angle tools) Y1 Main spindle speed: 8,000 min-1 Type VIII: Max. of 9 stations (including 3 adjustable angle tools) Motor: 5.5/7.5 kW Y3 Max. machining length: 320 mm/1 chucking (GB) B1 X3 Z1 Opposed spindle Main spindle speed:

INTRODUCTION Manufacture of discrete parts or assemblies using a continuous process are called Quantity production. This production system is justified by very large volume of production. The machines are arranged in a line or product layout. Product and process standardization exists and all outputs follow the same path. Helical Gear produced in Quantity CHARACTERISTICS OF QP Standardization of product and process sequence. Large volume of products. Shorter cycle time of production. Lower in process inventory. Perfectly balanced production lines. Production planning and control is easy. Material handling can be completely automatic. PROPERTIES OF QP ECONOMIC ORDER QUANTITY Economic order quantity (EOQ) is the ideal order quantity a company should purchase to minimize inventory costs such as holding costs, shortage costs, and order costs. This production-scheduling model was developed in 1913 by Ford W. Harris and has been refined over time. The formula assumes that demand, ordering, and holding costs all remain constant. Production cost curve and Economic Order Quantity FORMULA AND CALCULATION OF ECONOMIC ORDER QUANTITY The formula for EOQ is: where: Q = EOQ units D = Demand in units (typically on an annual basic) S = Order cost (per purchase order) H = Holding costs (per unit, per year)​ ADVANTAGES OF QP Higher rate of production with reduced cycle time.
